Key Features

• PREMIUM M35 COBALT STEEL – Crafted from High-Speed Steel containing 5% Cobalt (M35 Grade). This hardened alloy ensures superior heat resistance and durability compared to standard HSS bits, measuring up to 67 Rockwell Hardness. Ideal for drilling through tough, high-tensile materials like stainless steel, cast iron, and titanium alloys. PRECISION 135° SPLIT POINT – Features a fully ground 135-degree split point geometry that self-centers immediately upon contact. This active cutting tip penetrates faster with less pressure and eliminates "walking" or wandering across the work surface, removing the need for a pre-punch. 13-PIECE METRIC SELECTION – Includes a carefully selected range of metric sizes for precision work: 1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.5, 4.8, 5, 5.5, 6, and 6.5mm. Note: Includes useful intermediate sizes 3.2mm (approx. 1/8") and 4.8mm (approx. 3/16") for specialized fitting requirements. EFFICIENT & CLEAN DRILLING – The fully ground dual twist flute design ejects chips rapidly, reducing friction and heat accumulation. This preserves the drill bit's life and ensures smooth, accurate holes without burrs, even during heavy-duty continuous use. ORGANIZED STORAGE – Comes packed in a labeled, durable plastic index case (marked with HSS-drills). The inner holder tilts out for easy access and keeps bits organized by size, making it perfect for transport to job sites or keeping your workbench tidy.
