Blitz Bits® - Mechanic’s Length

Premium High-Speed Steel

Heavy Duty 3-Flat Shank Design (On 3/16" and Larger) 135 O Split Point Black Oxide & Gold Finish

Features:

• Engineered for heavy duty work, BLITZ 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, which has a special black and gold 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 BIT ® 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 like mild steel, stainless steel and non-ferrous materials • The special 3-flat shank design provides a positive no-slip grip – ideal for cordless, keyless chuck and conventional power tools • Shorter overall length increases rigidity.
