Ansblue Diamond Drill Bit Sharpening Tool,Portable Drill Bit Grinder, Iron-based Bit for Grinding- Blue

This has to be the worst piece of crap I ever bought. It's an absolute toy. First, the mandrel was bent so the device wobbled badly when spun. The first drill bit I attempted to sharpen clogged the abrasive so there's little chance it would "sharpen" anything else in that size slot. Then the cut - if you can call it that - was symmetrical. Anyone who uses drill bits knows there has to be a back cut so the leading edge of the bit can dig into the material. No way will the geometry of this toy allow that. It's in the trash, not worth the hassle of sending it back.

Do NOT waste your money on this garbage!!!! The thing is flimsy plastic that flexes; from the torque of the drill, from the presssure of your grip, and from any other force applied. You might find it useful as a template to make a real bit sharpener, but this thing will not do anything but screw up good drill bits.

The item was great, easy to use and worked great. Had a minor problem holding the grinder, but work great....

I'm happy with this purchase. It took a little practice but my bits are sharp. I install aluminum doors for a living and this sharpening jig will save me time and money.

...but it is. I tried it once and threw it away.

Very good tool. Sharpened my bits, even the bigger ones, no problem.

Keeping drill shop is in the sesa tea for my hobby. Using the tool helps to keep that job done. Perfect for a hobbyist.

Simple yet efficient drill sharper!! Used it for first time & works really well
