- TRUE M35 COBALT STEEL (5% Co): Unlike standard HSS bits that dull quickly, our bits are engineered with Premium High-Speed Steel containing 5% Cobalt. This creates extreme heat and abrasion resistance, making them the ultimate choice for drilling through tough materials like Stainless Steel, Cast Iron, High-Temperature Alloys, Titanium, and Hard Plastics.
- SMART QUANTITY ALLOCATION (High-Breakage Sizes): Small bits break easily—we know the frustration. This 69-piece set is strategically packed with extras of the most frequently used (and broken) sizes: 10x each of 1.0mm/1.5mm/2.0mm/2.5mm/3.0mm, 5x each of 3.5mm-5.0mm, and essential larger sizes up to 8.0mm. You will always have a sharp backup ready.
- PRECISION 135° SPLIT POINT: Designed with a self-centering 135-degree split point tip that cuts immediately upon contact. This prevents "walking" or skating across the metal surface, eliminates the need for a center punch, and requires less pressure to penetrate hard metals compared to standard 118° points.
- PROFESSIONAL PERFORMANCE & GEOMETRY: Manufactured to DIN 338 standards. The fully ground dual twist flute design ensures rapid chip removal, reducing friction and heat buildup. The straight shank fits securely into all standard cordless drills, drill presses, and impact drivers (standard chuck).
- ORGANIZED STORAGE CASE: Comes in a durable, labeled PP plastic index case. Each compartment is clearly marked with metric sizes for easy selection and organization. Compact and lightweight, it fits perfectly in your toolbox, garage drawer, or workshop bench, keeping your bits sorted and protected from rust.
