12.2mm Titanium Coated M42 High Speed Steel 8% Cobalt HSS Twist Drill Bit 100x10x3mm Dowel pins length: mmM42 steel is a super hard cobalt high speed tool steel containing 8% cobalt, with good toughness, high wear resistance, high cutting efficiency, and good hot hardness (Retains hardness even at high temperatures of the cutting edge.). Nanoscale gold titanium coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant. Can greatly improves hardness, wear resistance, and reduces the coefficient of friction. Sharp
