ALFA BBML74228 Blitz Bits Premium HSS, 31/64", 3-1/4" Flute Length, 4-7/8" OAL, Mechanics Length, Black & Gold Finish
Engineered for heavy duty work, BLITZ BITS® are high performance drills for production as well as tough maintenance applicationsMade 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 frictionThe strong web construction provides greater strength and rigidity to drill in hard-to-drill materials like stainless steel and titanium alloysThe buttressed cutting edge, with an acute rake, makes the BLITZ BIT® cut cleanly and accurately with less effortThe extra clearance behind the side margin reduces friction, enabling balanced cutting action with closer hole tolerances, at higher speedsThe extra clearance behind the side margin reduces friction, enabling balanced cutting action with closer hole tolerances at higher speedsPrecision ground 135° split point is self-centering and reduces thrustDesigned for drilling the widest range of materials like mild steel, stainless steel and non-ferrous materialsThe special 3-flat shank design provides a positive no-slip grip – ideal for cordless, keyless chuck and conventional power toolsShorter overall length increases rigidity.
