Product Features
- PREMIUM M35 COBALT STEEL: Constructed from high-quality M35 Cobalt steel with a specialized bronze finish, offering superior heat resistance, durability, and a significantly longer lifespan than standard HSS bits, especially when drilling through tough materials.
- COMPREHENSIVE METRIC RANGE: This 19-piece set covers all essential metric sizes from 1mm to 10mm in precise 0.5mm increments (1.0, 1.5, 2.0... up to 10.0mm). All bits are neatly organized in a durable iron index box with clear size markings for quick identification and safe storage.
- ADVANCED PILOT POINT (5mm & ABOVE): Sizes 5mm to 10mm feature an innovative Pilot Point design. This stepped tip acts as a built-in guide, delivering extreme centering accuracy with zero walking, eliminating the need for a center punch, and producing perfectly round, burr-free holes on breakthrough.
- 135 SPLIT POINT (UNDER 5mm): For delicate and precise smaller holes, sizes 1mm to 4.5mm utilize a 135-degree Split Point. This self-centering design ensures rapid, frictionless penetration into the material surface without slipping or skating.
- ANTI-SLIP SHANK DESIGN: Engineered for maximum power transfer. Drill bits 5mm and larger are equipped with a Three-Flat Shank to securely lock into the drill chuck and eliminate spinning under high torque. Sizes under 5mm feature a standard Straight Shank for broad compatibility.
