Purpose-Built 6 Counts Metalworking Ldeal For

These metalworking drill bits are made from high-speed steel with a sharp serrated center tip, allowing stable horizontal drilling after initial positioning for reliable continuous performance. The 135° split point design prevents bit wandering, so you can drill accurately without a pre-center punch.

The bits feature an electrophoretic coating and fully ground anti-rust treatment, ensuring burr-free, long-lasting sharp cutting edges. Fully ground spiral flutes reduce friction and heat buildup for faster, cooler drilling. Suitable for stainless steel, cast iron, aluminum alloy, wood, plastic, glass, tile, brick, concrete, and masonry.

This set includes 6 different sizes and fits most common drilling tools, including hand electric drills and bench drills with a chuck clamping range of 10mm or above.
