- Industrial-Grade M35 Cobalt Steel: Engineered with high-speed steel containing 5% cobalt (HSS-CO), these bits offer superior heat and abrasion resistance. Specifically designed to cut through tough, high-tensile materials like stainless steel, cast iron, and titanium alloy with ease.
- Precision 135° Split Point: The fully ground 135-degree split point tip centers immediately upon contact, preventing "walking" or skating across the work surface. This design requires less pressure to penetrate and ensures clean, accurate holes every time.
- 74-Piece Metric Workshop Stock: A comprehensive assortment ranging from 1mm to 8mm, providing an abundant supply of the most commonly used sizes. Perfect for professional workshops, machinists, and contractors who need reliable replacements on hand for continuous drilling tasks.
- Fully Ground for Efficiency: Manufactured to strict DIN338 standards with a fully ground body and dual twist flutes. This geometry maximizes chip removal and coolant flow, reducing heat buildup and extending the lifespan of the bit during heavy-duty use.
- High-Value Bulk Packaging: Note: These bits are packed in a sealed plastic bag (no index case included). This bulk packaging offers maximum value, allowing you to pay for premium tool quality rather than expensive storage, ideal for replenishing your tool chest or inventory.
