Industrial Length 9/64" Super Primalloy Cobalt Drill Bit

Durable Super Primalloy construction, matching our fractional Cobalt Drills. M-42 Cobalt alloy, with 8% Cobalt, outperforms standard M-35 alloy. Enhanced heat resistance, extending tool life when cutting tough alloys and hard materials like stainless steel, iron, and titanium. 135° split point design eliminates center punching, penetrates high tensile materials easily, and increases tool life. Gold surface treatment offers excellent lubricity, boosts drill life, and prevents corrosion. Proudly made in the U.S.A.
