Long-Lasting, Tough Drill Bits at Competitive Price
Mibro Cobalt Metal Master Drill Bit Set offers 17 pieces ranging from 1/6in. to 3/8in., manufactured with a cobalt alloy blended into high-speed steel for exceptional toughness. These bits are designed to cut through very hard or abrasive materials such as stainless steel and space alloys, making them ideal for professional and DIY use in India. The bits feature a 135-degree split tip that eliminates the need for a center punch and prevents skating, ensuring precise drilling. Larger sizes have 3 flats for a stronger grip in impact drills, enhancing durability and performance. The set's extra thick drill core provides rigidity and strength, offering excellent longevity and value over standard HSS bits, especially in demanding applications. Imported from USA, these drill bits arrive factory-sealed, with all duties included, in 11-13 days.

Suitable for Professional and DIY Use in India
Designed for hard materials, these bits are perfect for Indian workshops, construction, and home projects involving stainless steel and space alloys. Skip if working with softer materials or seeking budget HSS bits; impact driver compatibility enhances performance.
