Last year I picked up a Vevor MR-13A drill bit sharpener and I gotta say it is hands down better than the Drill Dr I had. I have salvaged so many bits and they are near perfect after sharpening. Dull bits, snapped bits - no problem, just shorter than before I started.
i’m on the fence as to what to buy first… a D-bit grinder? or a drill sharpener?… i can sharpen big twist drills ok by hand. have a snap-on swinging jig thingy for the bench grinder for smaller ones… i could sharpen my end mills on the surface grinder… if i had one of those fancy 5C collet blocks with the angles and index built in. why cant there be a one size fits all machine???
i have literally a hundred pounds of twist drills I’ve rescued from the scrap bin at my work. and piles of used end mills that just need a touch up.
That Vevor drill bit sharpener is good for up to 5/8" drill bits.
The Endmill sharpener (the yellow one) is good for up to 5/8 endmills, HSS or carbide, 2, 3, 4 flute.
Both are stupid simple to use.
The Dbit grinder does both, but they are finicky in setting up, knowing all the different angles… Unless it is an authentic Deckel, they need disassembled and fixed. The 3 different angle locking is inconsistent and slips easy. I would not have bought it if I had got the yellow one first.
Having said that, I have used the Dbit for sharpening annular cutters, but again finicky setting up.
i doubt i would ever find a dekel or justify the cost. theres not much used machine shop equipment in the PNW (the dry PNW, not the whiney wet PNW) and when it does show up its stupid expensive
