- PREMIUM M35 COBALT STEEL: Engineered with High-Speed Steel containing 5% Cobalt (M35 Grade). These bits offer superior heat resistance and durability compared to standard HSS bits, making them essential for drilling through hard metals like stainless steel, cast iron, and titanium without dulling quickly.
- OPTIMIZED SIZE ASSORTMENT (69 PCS): Stop running out of the sizes you use most. We specifically included higher quantities of the fragile, commonly used sizes: 10x each of 1/16", 5/64", 3/32", 1/8"; 5x each of 7/64" to 3/16"; plus essential larger sizes (2x 7/32", 1x 5/16").
- PRECISION 135° SPLIT POINT: Designed for immediate penetration. The 135-degree split point tip prevents "walking" or skating on the material surface and eliminates the need for a center punch or pilot hole, ensuring clean, accurate starts every time.
- EFFICIENT & STABLE DRILLING: Features a fully ground dual twist flute design for rapid chip removal, preventing overheating. The straight shank fits all standard drill chucks securely, while the chamfered end ensures a firm grip to reduce slippage during heavy-duty applications.
- ORGANIZED & PORTABLE: All 69 bits are housed in a labeled, impact-resistant PP plastic case. The layout keeps bits organized by size for quick selection, making it perfect for professional mechanics, workshops, DIYers, and mobile repairs.
