I would love to know if anyone can recommend a drill bit sharpener that is easy to use. Of particular interest is sharpening 135deg split point cobalt.
I have not tried any but seems users reviews are so varied when it comes to ease of use.
 
I have had good results with the drill doctor units and I doubt you could burn a bit with one. I probably use an angle guide attached to a small slow speed grinder the most as it is quicker for a touch up. I don't even try to sharpen the small bits anymore, just replace them. I use the standard black oxide bits the most and save the cobalt for tougher alloys.
 
I have only ever used the drill doctor. I would highly recommend it, it will eventually pay for itself when you stop buying new bits so often
 
I know this is kinda old but I saw it going through pages. The drill doctor is bullshit and not needed but if it works for someone then go for it. If you want to see how to sharpen a twist drill. And it's very easy.
Btw his channel is one of the best on YouTube if your into that stuff. I would guess if your burning up bits you possibly might just be.
 
^^^This! Learn how to do it!........... Your are a knife maker, tool guy & sharpener now! Drill bits aren't that tough to sharpen

I dont know If you watched that video but it doesn't matter. If you are a guy and into cool stuff and man tools his channel is amazing. Not to mention he is super smart and knows a bunch of stuff about tools materials ect. It is very educational and I have learned a bunch while watching great videos.
 
We used a Drill Doctor and a clone at the office with mixed success. With the cost of bits these days, it is easy to find M2,M42 or M35 bits up to 1/4" for less than $1, it doesn't make sense trying to sharpen them. Hi alloy bits over 1/2" do justify the time. Most of the drilling I do is 3/8" or less. your money would be better spent on screw machine bits(extra short so you drill a better hole with less runout), a variable speed(even one that uses pulleys) drill press, a basic drill press vise, cutting fluid, and technique practice. with proper use, even inexpensive M2 bits can last for 100s of holes in non hardened material.
research the material you are drilling for best rotation and feed speeds. here is a link for Arne/01 http://www.uddeholm.com/files/PB_Uddeholm_arne_english.pdf which should work for most oil/water hardening steels

Elmax which should work for most stainless and CPM steels http://www.uddeholm.com/app/uploads/sites/10/2017/05/elmax-eng_p_15_R1601_e7.pdf
