3/32" Titanium Nitride HSS SAE Straight Shank Right Hand Drill Bits (2 Pieces) (63906) by IRWIN. Titanium nitride coating extends the life of the bit; lasts up to six times longer than standard high speed steel drill bits. Heavy-duty web design provides extreme rigidity when drilling in metal applications. Shorter cutting lips reduce torque when drilling in high tensile strength materials.
