Why the Expert?
Abracs HSS Cobalt Drill Bits (Packs) – High-performance 5% cobalt alloy drill bits that stay sharper longer for tough drilling tasks. Thanks to the M35 cobalt-enriched HSS, these bits offer increased strength, heat resistance, and wear life compared to standard HSS – meaning they drill more holes before dulling, even in hard metals and stainless steel. They’re precision-ground and feature a 135° split-point tip for easy starting with no center punch needed, providing accurate, fast drilling and less bit wander. Sold in convenient packs of popular sizes, Abracs cobalt bits are ideal for professionals who demand long-lasting, high-speed drilling through metal (while also handling wood and plastic) with minimal downtime for bit changes.
