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

I requested a replacement and got it in a few days. I have yet to send the incomplete one back, because Kohls and any other non-essential businesses have been shut down due to Covid-19 outbreak again. It takes a little doing to set this up. I first tried it on the face of my 8" grinder with poor results. Problem with setting up on the face are: If to high, you will grind the heel too much. If too low you will grind the point too much. If you are going to grind different sizes of drill bits you will be constantly trying to adjust the height to be exactly at the center of the wheel. I then tried mounting this tool to the side of the 8" grinding wheel and got really good results. Just be careful to grind very small amounts so you are not putting much pressure on the side of the grinding wheel and this will also keep the temperature of the drill bit low so you do not change the temper. I have had no noticeable grooves in the side of my wheel and I am getting nice sharp drill bits. Always, Always wear a face shield and protecting eye glasses just incase.

This thing is awesome. Getting it set up right the first time is a tiny bit challenging but not too bad. Works great once it is set up

When aligned does a fairly good job. Much better than drill doctor. Take a little time to get bit and guide to engage correctly. I use mine with a diamond wheel.

This drill bit sharpening tool is intended for the hobbyist who has the need to sharpen a few bits occasionally. One major problem is you have to use a bench grinder and mount both to a solid surface at different heights. It functions pretty well but takes some experimenting to get it right. It will sharpen a bit correctly. It's not recommended for very small bits.

I'm very happy with this attachment. For the price it works great! If I had any criticism it would be the setup directions. What helped me was when I realized that for it to work correctly for me, the installed drills grinding position (where the drill tip will contact the wheel) must be intersect with the grinding wheels vertical position (90 degreeses from the attachnents mounting surface) And the guide for the drill tip possition be exactly as noted in the provided instructions. I did have some issues with the attachment when I first unpacked it, but was very pleased with the responce from the Generial Tools technical support team. Unless your willing to spent a lot more money, this is a great tool addition for a hobby work shop.

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.

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.

Works good. However you must attach this to a bench grinder that is on a bench-top with the grinder set back a bit from the edge of the bench top. Could not mount it when the grinder was on a post stand

Does a good job, but bit fiddly to set up. Replaced couple of the adjustment screws with hand screw adjusters, as this makes setting different drill size bits much quicker and more accurate. Once set up properly to grindstone it works very well. Take your time getting the angles right and practice with a couple of old drills and results will be good. Did a lot of blunt drills, which now cut really well, set the cut angle to shallow cut for hard metals, excellent results through thick steel.

Muito bom, chegou rápido e tem um bom acabamento!
