About this item

• PREMIUM M35 COBALT STEEL: Engineered from top-tier High-Speed Steel blended with 5% Cobalt. This premium composition provides superior heat resistance and lasting durability, easily powering through tough metals like stainless steel, cast iron, and titanium.
• OPTIMIZED SIZE ASSORTMENT (69 PCS): Never run out of your most essential sizes again. We packed this set with extras of the most fragile bits: 10x each of 1/16", 5/64", 3/32", 1/8"; 5x each of 7/64" to 3/16"; plus larger heavy-duty sizes (2x 7/32", 1x 5/16").
• PRECISION 135° SPLIT POINT: Designed for immediate, dead-center penetration. The aggressive 135-degree tip prevents skating on flat or curved surfaces and completely eliminates the need for a center punch or pilot hole, ensuring accurate starts.
• EFFICIENT & STABLE DRILLING: The fully ground dual twist flute design forces rapid chip removal to prevent overheating and friction. A straight shank with a chamfered end ensures a slip-free, secure grip in all standard chucks during heavy applications.
• ORGANIZED & PORTABLE: All 69 pieces are securely housed in an impact-resistant PP plastic case. The labeled layout keeps every size neatly organized for instant identification, making it the perfect companion for mobile repairs, mechanics, and DIYers.
