hey guys
long story short sometimes when i drill holes they harden when i cool with oil, so far i had no means of annealing but i bought an HT oven so few days ago i tried annealing O1 and k100 together
set to 1460F for an hour and let them cool inside the oven overnight
i already had all the holes established with smaller bit (5mm), one the O1 blade i had very thin bit of steel remaining from the larger (8mm) bit, and on the k100 most of the steel was intact, anyway after annealing the drill bit still didn't go through and kept squeaking (tried several bits)
any ideas?
