I'm having trouble drilling 80crv2. First I tried heating it to blue in my forge. Didn't work of course. Then I tried bringing it up to non magnetic and letting it cool down with the forge. Still no luck. I'm using a titanium bit. It gets just through the surface and makes the terrible screech. Anyone have any ideas?
 
Look around, online is great, and get you a total carbide bit--I've found the carbide tipped ones don't last worth a toot.
 
Get new bits
Lube lube lube

Pilot holes are your friend much easier for the bits to bore through

Double check annealing temps?
 
Also drill slow
the screech is because the bit is dull and it's not cutting

Also remember if you drill fast your likely to toast your bit due to heat

Heat is the bits worst enemy.

Sorry if this doesn't help I don't know the limits of your skills
 
Thanks for the replies. I'll try the above mentioned. The bit I used was not carbide so that might be it. Also not sure what temp to anneal at but will keep at it. Thanks
 
Anyone else used Aero Pro Tech carbide bits? They're considerably cheaper than others I've seen and they have a very large range.

Anyone have any advice on how to sharpen carbide bits?

Used one bit on several K390 blades at about 63 RC and it's time to sharpen it. Wondering if normal Alox sanding disks would work.
 
fully annealed should drill like mild steel with a new bit slow and oily, if I run into a hard spot I switch to a solid carbide bit, I basically only use three bit sizes so keeping a carbide bit for back up is affordable
 
Thanks for that info. I must have sorry bits cause I can cut it with a file lol. It should drill plum through fine with slow speed and lube. I'll get some new bits and try.
 
Try cobalt bits and oil. Run the drill press slow.
