General Tools Drill Grinding Attachment #825 - Drill Accessories - For use with ANSI, OSHA, and UL

Work well for what I need it for.

yes, the instructions are a bit cryptic, and I needed a few reads to understand fully, but it does sharpen drill bits very well. I have a fairly good grinder wheel (120 Grit Silicon Carbide) and with some practice, I now have drills that do well using my hand drill and drill press. And after some more practice with this attachment, using the sharpened drills in my bench metal lathe now makes holes that are not larger than the size of the drill.I recommend this drill bit sharpening attachment to anyone who uses drills often and is willing to invest a little time to master it.

Quality is not amazing but price is right.

says general brand. came in a blister pack. If you have never used one of the old ones, good luck. The instructions with this one are a joke. These fixtures take time to set-up correctly. once set-up they work very well for general purpose sharpening. I use an old bench grinder, set-up on a solid base and keep it under the bench.Use a good trued wheel and you can learn to split point. Why did i buy a new one? Gave the set up to a friend. This one looks like made in china, I hope Taiwan.

does a great job with drills 1/8 thru 3/4. You get the same sharpness every time and it is quick. Look at some youtube videos for better instructions.

This sharpener works great! You have to spend a little time working on aligning the cutting edge of the bit against the sharpener but once you figure out how to get the indexing right on that aspect you can quickly mount and sharpen your bits. The handle and wing nut in the photo are purchased off Amazon M-12 bolt and handle with M-12 wing nut. The slot is a little smaller than 12mm but I just filed it out a bit to accept the 12mm bolt a 10 mm prob fit a little loose but no filing. Make sure your mount is solid and squared up to your sharpener.

Greek product, but not for some.I used this for the first time and fixed some of my dull bits and brought them back to factory or possibly even better. I sat there with a friend and lent it to him and told him how to do it, but he messed up all of his bits even more. I guess it depends on the person.

I set mine up on a belt grinder. Throw away the included instructions which are useless and incorrect. This grinding attachment was originally sold by Snap-On Tools and you would be well advised to find those instructions for proper set up. I found them from pictures of the inside of the box. Or look up a few online videos. Works great all the way down to 3/16" bits. I wouldn't bother with smaller sizes as they are inexpensive to replace.
