Woodworking Square Hole Drill Bit Sharpener Mortise Chisel Bit Sharpening Tool Up to 1/2" Bit Grit #220/600-2Pack

Just received them. Works like they should. Don't know how they'll last. But good right up front.

These are not exactly what I was looking for but, they get the job done!.. I have no complaints it was worth the price and I saw what they were before I bought them. Thanks!!

Good product

All good

One reviewer stated that the foreign made square hole mortising bits are usually either 55 or 60 degrees & the sharpening cones are the opposite degree. I can't remember now what that guy said. When I received my cones the 1st thing I did was check the angle of degree on both. The course cone is a solid 60 degrees & the fine cone is a solid 55 degrees. Go figure. So now what the hell am I supposed to do? I've been so busy I haven't had time to check the angle on my square hole bits yet. Another couple of reviewers said that the fine cone shed the diamond coating when used in a drill & suggested using them by hand & just spining them that way. If the fine cone fits I think I may be able to use it to sharpen my bits. The course cone seemed to rough to put a fine edge on the bits. I'll update after I actually put them to use.

THIS TOOL WORKS GREAT.

I haven't used them yet but they are a great idea. I don't know how I would have sharpened my chisels without it.

These are quite easy to use even for a novice. The price is great and the quality is fantastic. Using them as a sharpening tool has tightened up some of my artwork on wooden stands I make for gemstones. Definitely would purchase again and recommend.
