【What is M35 Cobalt?】
–ºThe addition of 5% cobalt increases drill bit's heat and wear resistance, which makes it perfectly suitable for Stainless Steel and Cast Iron. M35 Cobalt steel drill bits can penetrate a 5mm-thick 304 stainless steel plate in 5 seconds.
–ºWhile the 5% cobalt makes the bits much more durable,it also makes them more brittle than ordinary HSS bits under improper usage.

【How to use this Drill Bit? Here are some warm tips】
–ºKeep the bit vertical and fixation while drilling.
–ºTo avoid drill bit break, 1/16" or smaller bits are suggested used with pin vise.
–ºPay attention to the cooling of the bit, adding water or coolant when drilling can increase the life of the bit.
