Has a bit more power than the 1/4 inch Makita GD0601 above, at 4.2 Amps (but has the same 25,000rpm max), and you can use it for many of the same tasks.
It still maintains the 1/4 inch collet cone piece so can take a wide range of attachments and bits – and has the option to buy an additional 1/8 inch reducing size sleeve.
The collet nut and collet itself are actually a single piece which reduces bit changing time

It can do alot – from cutting, to grinding, polishing, sanding, sharpening and more. The long shaft gives you extra reach when working with
Aside from the power, it comes with plenty of features like the SJS technology, variable speed control, side handle.
One small design negative we did identify is the collet design. Some bits can get stuck/jammed in the collet cone and can take some effort to remove. Although this doesn’t happen frequently, it is something to be aware of if you are constantly changing a range of bits and attachments.

7. Ampro A3028 Gearless Angle Head Die Grinder and 2-Inch Angle Sander – Best Right Angle Die Grinder & Best Air Die Grinder For Grinding
We rated the Ampro as the Best Angle Die Grinder and the Best Air Die Grinder.
It is perfect for grinding, polishing/smoothing, sanding, finishing – but, it not so much a cutting die grinder.
It will suit either an amateur or a workshop/production type user and environment.
The first major positive is the price. Secondly, its powerful, smooth, and very easy in terms of vibration on the hands. The gearless design makes for a near faultless construction for longevity of the tool.
It’s very hard to find a negative review about this die grinder other than the fact that it is slightly noisy.
It is worth nothing that Ingersoll Rand do a similarly high air die grinder to this one which made of metal and intended for automotive and light maintenance applications – the Ingersoll Rand 301B Air Angle Die Grinder.
We would recommend this Ingersoll model almost as highly as the Ampro. Just be aware some of the accessories for this Ingersoll can be expensive so look at that before buying. The link for the Ingersoll we’ve included below under the Ampro.
- Very affordable (only slightly more than the Ingersoll Rand 3107G)
- Tops out at 25,000 rpm
- Gearless mechanism for operation
- Comes with a 2 inch angle sander attachment
- Lightweight
- Throttle lever doesn’t have any ‘sticky’ problems
- A little loud – make sure you have hearing protection
- Mainly for grinding and sanding/touch ups
- Uses a little more air than some air die grinder at 4 – 6 Cfm (170 L/Min).
Final Word
If grinding, sanding and finish are your main priorities – you probably can’t do better than the Ampro for its price.
If you want to cut, there are better air and electric die grinders out there for you.

As mentioned above, the Ingersoll is also right up there with the Ampro as a terrific right angle die grinder:

8. Ingersoll Rand 5102MAX Air Die Grinder – Second Best Angle Die Grinder
There is not much wrong with the Ingersoll Rand 5102MAX – there’s a reason we rated it the second Best Pneumatic Angle Die Grinder.
It’s lightweight, has an all ball bearing construction, has the safe release throttle, is comfortable to use and has a HEAP of power at 0.4HP and 20,000 to 25,000rpm.
So, you won’t have any issues with the quality, performance or longevity of this tool.
Like the Ampro, it is mainly for grinding, polishing/smoothing, sanding, finishing. Get a straight die grinder if you want to cut.
To be 100% honest, we couldn’t find any negatives other than the fact it is a little pricey.
Great for either a workshop, or backyard use.
- Good power and speed
- Quality performance and construction (for long life)
- Comfortable operation and grip
- Throttle lever and safety is well constructed
- Seems to be quieter than the Ampro

6. Types of Die Grinder Attachments, Wheels and Discs
Generally, right angle die grinders are used more for grinding, sanding and polishing, whilst straight die grinders are used more for cutting, burring, contouring and the more precise tasks – and this should be taken into account when choosing a die grinder and attachments.
Die grinder attachments usually come with the bit attached to a spindle/shank (1/4 inch is the most common) that screws into the collet cone and is tightened into the grinder with the collet nut. Some models of larger die grinders allow reducer sleeves to allow smaller attachments.
Die grinder attachments fit into the following main categories:
- Die Grinder Grinding Discs and wheels
Come in different sizes, materials, grits and usually with mandrels – generally 1 to 3 inches in diameter, and common types are standard metal cutting and diamond cutting discs for use on wood and metal/steel.
- Die Grinder Cutoff Discs and Wheels
Thicker than cutoff discs at around 2 to 4 inches, and are made of reinforced material, but generally have a similar setup. For use on metal, stainless steel and alloys.
- Die Grinder Sanding Discs and Backing Pads
Discs come in different sizes and grits.
- Die Grinder Flap Wheels and Discs
Come in different sizes and materials such as woven flap wheels and zirconium roll on flap discs.
- Die Grinder Mounted Points
Mounted points are small abrasive bits that come in a range of shaped and are used to produce sharp, consistent cutting action in almost every industry, but primarily in tool and die shops, and foundries. Ideal for deburring, tool sharpening, finishing cavities, and removing mould marks and parting lines.
- Die Grinder Roll On Discs
Roll on surface prep discs and buffing discs are common.
- Die Grinder Rotary Burrs and Rasps
Rasps and burrs are generally made of carbide, stone or heavy duty materials, and come in all types of shapes such as cones, pear-shaped, round end, flat end, drum-shaped.
- Die Grinder Wire Wheels and Brushes
Generally come in crimped and knotted forms, and can be made with brass wire, nylon bristle and steel knot.
- Miscellaneous Attachments
Buffers, eraser pads, etc.
7. Die Grinder Guards
Die grinders may or may not come with a wheel guard. They are generally referred to as protection shields.
You want to check if a protection shield is available particularly when working with the shorter die grinders and cutoff wheels.
8. Die Grinder vs Dremel Tool
Die grinders and Dremel tools are both rotary tools, and have the same basic function or use which is to cut, grind, sand, polish etc. via rotational force of the associated bit you attach to the tool.
However, there are some key differences when comparing a die grinder vs dremel tool that set these two tools apart:
1.Dremel is an actual brand! – Dremel is a brand that manufactures their own range of rotary tool, and have established themselves to the point that the brand is what is generally used to describe that type and range of tool.
Die grinders on the other hand are made by many different brands, and there are several types and variations of die grinders.
2. Die Grinders are generally much more powerful – the common way to describe a die grinder is as a Dremel on steroids. When comparing Amps, Horsepower and the main power specs, die grinders win out.
This extra power makes a die grinder generally alot more suitable for working on metals and performing the more demanding tasks and bigger jobs, like in workshops and industrial environments for example. Dremels are more commonly used for finishing activities, hobby and home environments, and smaller jobs.
However, you can definitely perform smaller and finer jobs with a die grinder too – get the right die grinder, get the right bits, and if necessary – vary the speed to match the activity.
3. Dremels spin faster – In terms of rpm of the bits and attachments, Dremels can max out on average at around 35,000rpm. Die grinders on the other hand top out at around 20,000 to 25,000 rpm for most models.
The smaller the discs or wheel or bit, the less distance it has to spin in diameter, and hence the extra speed.
4. Die Grinders are bigger in most ways – Generally everything is bigger when it comes to a die grinder, especially when talking about electric die grinders.
You can get small die grinders, but even the small die grinders are powerful and tend to have larger attachments, bits and discs than most Dremels – in terms of dimensions.
For example, a shank on a die grinder is generally 1/4 inch, and Dremel tool bit shanks are generally 1/8 inch.
5. Dremels are mainly electric powered – the standard Dremel is electric powered. Die grinders on the other hand can be either electric or pneumatic/air powered.
It generally takes more power to run a die grinder.
9. Die Grinder Safety Checklist, Rules and Tips
Here is a list of just some of the angle grinder hazards to watch out for, and some precautions you can take:
Kickback on the grinder if there is no soft start – consider a soft start grinder
Speed control – a feature that maintains the motor speed if the disc stalls or gets stuck and protects you against the tool jerking or kicking back on you
Grinder stays running if there is no quick release switch – paddle switches and trigger switches can work well if you drop the grinder
Disc or attachment breaking – get a disc or attachment/bit which can take the rpms and the tasks e.g. use a diamond blade for tough metal, and check disc/bit condition regularly.
No presence of a guard or shield – generally you can be ok to use a die grinder without a guard, but if you are using a short type die grinder, you want to consider a protection shield as your hands can be close to the cutoff wheel
Not wearing gloves, eye protection and safety clothing like an apron – especially if grinding for long periods
Inhaling dust or fumes – wear a dust mask for dust heavy tasks
General shards, offcuts and grinding material hitting you – wear PPE
Motor overheating – get a quality die grinder and wear gloves when using for extended periods
The level at which sustained exposure might result in hearing loss is 90 to 95 decibels – check the decibel rating of any tool you buy and wear hearing protection if necessary.
10. Other Die Grinder Features and Accessories To Look For
Do you want a variable speed die grinder, or single speed die grinder?
Do you need an electric grinder, or will an air die grinder better suit you?
What rpm, or speed and torque, do you want out of the wheel?
How much amperage and horsepower do you require for your task?
What are the parts that come with the grinder you want to buy? Can you get grinding AND cutting parts – wheels and attachments? Will the collet cone size fit the bits you want to use?
Will a straight die grinder or right angle die grinder suit your needs better?
What is the motor and gear protection like, as this contributes to longevity of the tool
Is there a level of vibration and noise control on the grinder?
Do you need a longer or shorter die grinder, and do you perhaps need a micro/mini/pencil type die grinder?
Will a standard 1/4 inch die grinder suit your needs, or is a 1.5 inch die grinder or 2 inch die grinder better?
Consider the size of the air compressor you need if purchasing an air die grinder…generally for most quality air die grinders you don’t want an air compressor with any less tank capacity that 25 gallons.
Check the air intake requirements of the air die grinder you purchase – intake per minute, cfm, psi?
11. Advice And Tips For Buying Die Grinders Online and In Store
For first time buyers, or even for seasoned tool users, here are a few tips and things to look out for when buying the best angle grinder for you in store or online:
Know the difference between consumer and commercial/industrial tools – commercial tools are built to last longer!
Sold and shipped by – check who the tool is actually sold and shipped by online if its not the actual manufacturer or Amazon. If it’s a 3rd party tool store or tool seller, make sure you research them and their commitment to quality and honouring warranties (you don’t want to buy defective equipment or buy through a seller that doesn’t honor warranties). On the right hand side of the page it says ‘sold by’ in Amazon – research that company.
Check the Seller’s Warranties on their site – the good warranties usually give you a) money back period (30-90 days), b) full 1 year warranty or similar, and c) multiple year part warranty. Check the manufacturer/sellers site for details.
Be careful of buying reconditioned tools!
Always read what is included in your purchase – discs, guards, batteries, chargers, disc changing tools, cases and other accessories can be sold separately.
Unfortunately a lot of tools are made in Asia these days. Check where the tools have been made, and assembled for quality.
Double check the tool manufacturer site for your country’s tool specifications and policies – tools parts can vary slightly country to country and have different company policies by country.
