135 Deg Split Point Drill Bit w/ 3 flats, 1/2 Dia, 3-3/8 Flute, 5 Length, Alfa Tools BBML74229

These 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 135O 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.
