Nitrided Premium High-Speed Steel For Extra Tough Performance

Extra Heavy Duty 135 O Split Point Black Oxide & Silver Finish

Features:

Blitz Nitride ® - Jobber Drills

• Engineered for heavy duty work, BLITZ NITRIDE ® bits are high performance drills for production as well as tough maintenance applications • Made from a premium grade of M-7 molybdenum high-speed steel, with a special nitride treatment, giving additional hardness to the cutting edge for tougher applications, and with a black and silver surface treatment to increase lubricity and reduce friction • The strong web construction provides greater strength and rigidity to drill in hard to drill materials like stainless steel and titanium alloys

• The buttressed cutting edge, with an acute rake, makes the BLITZ NITRIDE ® bits cut cleanly and accurately with less effort The extra clearance behind the side margin reduces friction, enabling balanced cutting action with closer hole tolerances, at higher speeds • Precision ground 135 O split point is self-centering and reduces thrust • Designed for drilling the widest range of materials including mild steel, stainless steel, titanium and nickel alloy steels and non-ferrous materials
