thanks alot for all the info guys. i think ill try some of the ideas here. ill post some more photos of the drills that didnt cut properly later today when i get back.

this might all be my fault all together. i think ive been a bit quick when getting to drill bit nr 50 for the day. below 3 drills with explanation.
question: Is there any reason for the secondary bevel to be there on drill bits from 3 - 6 mm? what good does it do? i know its suppost to keep it from wobling about, and to make you drill without that much preassure. but besides that should it not cut about the same?

the way i see it. the more you grind in the secondary facet the more you remove from the cutting edge near the center of the drill. witch i think again makes the center cut alot worse than it needs to.

For some reason 5 of the 80 bits i sharpened seem to be sharpened the "wrong" way around. the cutting bevels wont even touch the material one is trying to drill. i have no idea what so ever why this happened or how its even possible. kinda hard to explain but see pictures. this one obv didnt cut at all.

Here is one that didnt cut. i did not bother to cut the seccodary bevel on this one just as an experiment

Here i can tell the secondary bevel was not ground far enough. that is my bad, but is there any reason for this one not to cut properly. The primary cutting bevel is the only one that is touching whatever you are drilling anways. should kinda think it would work just as well as a perfectly 4 faceded one.

sorry for all the stupid questions. but i apreciate all the help :)

Howdy folks. I have recently aquired myself a DBS-22 that im going to use for metalwork. i have sharpened about 60 drill bits so far. and everything was looking perfect. most of the drill bits are made of HSS steel and around 5-12mm in diameter. after sharpening them all i tried drilling with them in both aluminum and mild steel. but they wont cut at all. not even the smmaller ones. i am using the correct angles and everything. but it seems to me that the "center of the drill" wont cut comparet to a "new" one the primary facets dont cut the center. is there anything i can do to fix this issue? or is it just one "flaw" of the 4 faced sharpening method? if i predrill with say a 3mm for a 6mm hole everything works like a charm. but i dont think that should be needed for a 6mm drill. Thoughts?
