- PREMIUM M35 COBALT STEEL: Crafted from High-Speed Steel containing 5% Cobalt (HSS-CO), these bits offer superior heat resistance and wear durability compared to standard HSS. Ideal for drilling through tough, high-tensile materials like stainless steel, cast iron, and titanium alloys.
- PRECISION 135° SPLIT POINT: Features a self-centering 135-degree split point tip that cuts immediately upon contact. This design prevents "walking" or wandering across the work surface, eliminating the need for a pre-drilled pilot hole.
- FULLY GROUND FOR ACCURACY: Unlike cheaper rolled bits, our 9.5mm bits are fully ground from solid hardened steel. This ensures strict adherence to DIN338 diameter tolerances, precise concentricity, and a smoother flute for faster chip ejection.
- EFFICIENT PERFORMANCE: The heavy-duty dual twist flute design and amber/bronze finish reduce friction and heat buildup during continuous drilling. The straight shank with a chamfered end ensures a secure, non-slip grip in standard drill chucks.
- SPECIFICATIONS & STORAGE: Includes 5 pieces of 9.5mm metric drill bits. Working Length: 83mm; Total Length: 125mm. Comes in a durable, transparent PP storage case for easy organization and protection in your toolbox.
