Produktbeschreibung

Fast Chip Removal - Twist drill bit features spiral flute design that clears debris efficiently, achieving 30% improved drilling speed compared to standard bits. Ideal for high-volume metalworking projects. Accurate Engineering - 118° point angle and 25.5mm working end maintain ±0.1mm drilling accuracy, ideal for automotive repairs and metal fabrication where exact measurements matter. Industrial-Grade HSS - High speed steel construction withstands 600°F heat without losing hardness, outlasting carbon steel bits by 5x lifespan in demanding applications. Multi-Material Versatility - Specially hardened working ends work on 8+ materials including manganese steel and quenched alloys, eliminating the need for multiple specialty bits. Secure Grip Design - 1/2in straight shank prevents slippage in chucks, while the 97mm working end length provides optimal balance for both handheld and bench drill use.
