NEIKO 10649A Micro Air Die Grinder | 1/8" (3mm) Capacity | Pencil Type | 54,000 RPM | For Cleaning Dies, Rotors, Backing Plates, Brake Pads, Mounts, Etc.

I picked this up as a more affordable alternative to some of the higher-end butterfly impact wrenches, and I've been very happy with it. It has plenty of power for the jobs I use it for, and the compact design makes it easy to reach fasteners in tight spaces where a standard impact wrench won't fit. The butterfly throttle is easy to control, and switching between forward and reverse is quick and intuitive. It feels solid in the hand and has performed reliably every time I've used it. If you're a home mechanic or just need a compact air impact without spending a lot of money, this is an excellent value. It does exactly what it's supposed to do, and I'd definitely recommend it as a budget-friendly alternative.

Works good,saved money by not buying or needing anything more expensive for DIY repairs. Take it easy while tooling is extended out too far,they will bend or break but usually always user error.definitely a 7/10 product! Will buy Neil products again .

Got to use this today and decided to see what 50,000 rpm looked like. While just holding it without touching anything my Dremel wire brush immediately went pear-shaped . Good thing it stayed in the chuck otherwise it may have gone suborbital. I don’t think I’ll try anything other than burr tips from now on. Other than that it appears to be good quality and runs great. No instructions on how to oil it except to put it at the inlet port which is at the end of the 3 foot hose. I suppose you could disassemble the housing and put oil directly into the turbine inlets but that seems like a hassle.

So far so good

Out of the box worked great, after about two hours of use it didn't want to start moving. Tool was oiled and not abused until after the issues. After the grinder wouldn't start moving, striking the grinder while the was air running let it start moving and working great. Still works just needs to be jolted for it to start. Very compact tool

I picked up the NEIKO 10649A Micro Air Die Grinder (1/8" capacity, 54,000 RPM) for fine deburring and cleanup work in the shop, and it’s quickly become one of those tools you wonder how you worked without. What I like: Slim pencil design — super easy to control for precise work Runs very smooth at speed — minimal vibration, even at 50k+ RPM Perfect for carbide burrs and small abrasive tools Lightweight and comfortable for longer use Great power for its size — it doesn’t bog down on light metal work I’ve used it for cleaning up edges, removing tiny burrs, smoothing pockets, and general detail work where a full-size die grinder would be overkill. As long as your air system is clean and regulated, this thing runs beautifully. Shop tip: Use a fine-mist oiler and keep your air dry — these high-speed pencil grinders like clean lubrication. If you need a precision air grinder for delicate cleanup, polishing, or light detail machining, this one is a great value for the money. I’d definitely buy it again.

First u have to oil it! Every day you use it! It is not a turbine grinder it is a pencil grinder! Turbine grinders run dry oil will slow them.. pencil grinders will get hot in hand if not oiled from friction. They will gal and loose rpm permenatly! Dont use a moisture trap u have to oil it! Second if tool or burr runout is so paramount u cant have a .001" runout u need to have as little bit sticking out as possible if it is not solid carbide or the bit itself can bend and cause vibrations from the speeds. For $40 u will not find a better option. In fact under $175 u wont! This one is better than the blue astro brand because if the hose is cut or burned it can be cut and re installed. The astro is crimped and much more difficult to repair. We use these on hardened die steel daily. Very good but our mind carbide bits spin tru. If u have issues try to re install in the collet at a proper amount of torque. Alternatives are $600 dynabride turbine grinders that run even faster but when u add pressure to the cut they lose speed. Not only that they break doen easy i could see buying one but our shop has about 10 in parts all broke over time. We reused parts from old ones as long as we could. These little pencil grinders can do 98% of yhe jobs. They are really amazing. So often we have to weld and rework the hardened steel in very confined areas no angle grinder could fit. These do the job and do it great. At about 3 hours use per week they last 12-18 months. They still work but are slower. They could be takem apart and renewed with new parts but for $40 why.. the parts will cost over half that alone..

Worked well with Walnut blast media. Would recommend getting the extension for it.

Not used but at looking it's good i will write my detail review after using it.

This is identical to the Astro which costs more. Made in Taiwan. Works very well so far. Smooth and speed control is very good. The other reviews of the Astro lead me to believe it will last a long time. Excellent product for the money. With good Burrs it trims metal with great control. Much more versatile than a Dremel.

it does not do what its supossed to do waste of my money.

Justo lo que necesitaba

... An EXCELLENT little tool .... to be used carefully .... very lightweight ... particularly good for very light/delicate polishing and or modelling work ... very well made ... but be careful its not abused ... I use it for work that the 'Dremel' is too brutal for ... I am VERY happy with it.
