Vevor drill sharpener

[ltlvt]

If you search on drill doctor and rjsakowski, you will come up with my comments on the tool. I didn't do a specific writeup on the Drill Doctor. I bought the 750X. I sharpened over 100 drills with it.

The Drill Doctor will sharpen two equal edges and create a clean and sharp cutting edge. However, unless particular care is used, you can end up with a negative relief for the cutting edge and a drill that won't drill. Also, it indexes off the flute on the drill and all flutes aren't the same. A different flute width or helix pitch will change the indexing on the grind. It works, but it is finicky. I have tried making split points with it but they aren't right so I mostly grind a 118º point.

Doing it over, I would opt for the Vevor instead. It costs more but the aggravation of grinding a drill that won't cut doesn't justify the lower cost of the Drill Doctor.

I bought the Drill Doctor first and have had the same results as you. Watch Wes Work did an in-depth review of both. After watching his videos I now know why the Drill Doctor is hit and miss. i thought I was just too stupid to use it the same every time. His videos finally tied the knot for me and I spent the money on the Vevor. Not all of Vevor's stuff is good but the items that are good are terrific.

I purchased the Vevor unit a while back and finally got around to trying it out on a few different sized bits. Seems to work really well. I got the one that went up to 15mm, and purchased a set pf ER20 collets to cover a few of the smaller sizes that weren't covered with the included set. I have several boxes of used bits I inherited from my dad so hopefully I'll find some time this winter to get them all sharpened up. Mike

The Vevor sharpener is handy I've sharpened many drills on the D-bit Grinder but it's a little complicated to do a 4-facet grind. Well, not difficult, just lots of steps. A dedicated drill sharpener is quick and easy. Small screw machine drills are somewhat difficult to align in the fixture.

There have been discussions of the Vevor drill sharpener, here are a couple, probably others if a search were done.

Are drill bits consumables?

Bought the Vevor as well, but do keep the older original version of the DD for doing the bits that are larger than 1/2" up to 3/4"
