HSS Drill Bit, 28 mm Cutter Diameter, 1/2 in Straight Shank, Spiral Flute Design for Metal Drilling on Steel, Aluminum, Copper

Produktbeschreibung

Rapid Chip Evacuation: Engineered with helical flutes to streamline debris removal during quick drilling; Minimises heat generation and bit clogging for uninterrupted operation on thick steel plates or alloy surfaces; Maintains consistent drilling speed even in deep-hole applications Material Integrity: Forged from hardened HSS for edges retention under extreme friction; Withstands prolonged use on hardened steels like manganese or quenched components; Resists deformation during torsion tasks in industrial workshops Accurate Edges Geometry: Features a 118-degree split point tip for reduced walking and immediate bite initiation; Micro-ground cutting edges ensure clean boreholes with ±0.1 mm tolerance in metals for accurate tasks requiring repeatable accuracy in fabrication or automotive repairs Multi Metal Compatibility: Optimised for drilling iron castings, aluminium extrusions, copper pipes, and stainless steel sheets up to 12 mm thickness; Performs reliably on annealed steels and tempered alloys without premature dulling Ergonomic Shank Design: 1/2-inch straight shank ensures firm chuck grip across drill presses and handheld drivers; Balanced weight distribution reduces operator fatigue during extended drilling sessions
