Irwin HSS PRO TiN – 3mm

These IRWIN HSS Pro Titanium NitrideDrill Bits are designed specifically for drilling into metal and tougher alloys. TiN is a terrible conductor of heat which sounds like a bad thing but its actually very good because the heat generated from drilling will be transfered into the chips instead of your bit. A cooler bit means a longer life. The body of these drill bits is made from the highest quality HSS and coated in Titanium Nitride to up the strength, lower the friction, and keep you working as efficiently as possible.
