The BSC PREFERRED QJDIB-DB-041 is a 3/8-inch cobalt drill bit engineered for industrial-grade performance in hard and abrasive materials. It features a 135-degree split point that initiates contact quickly and eliminates walking for accurate hole placement without a center punch. A reinforced core design resists bit breakage under high-torque drilling conditions. This bit is rated for up to nine times the service life of standard black oxide bits, making it a cost-effective choice for shops and field technicians who drill frequently into tough substrates like stainless steel, titanium, and hardened alloys. It can also be used in wood and PVC when needed.
This cobalt drill bit is suited for use in fabrication, mechanical, plumbing, electrical, and HVAC service environments where drilling into hard materials is routine. Its durability makes it appropriate for both bench drill press use and handheld electric drill applications. Trade professionals who regularly work with stainless steel fastener holes, conduit knockouts, or structural metal will find this bit handles repeated use without the premature dulling common with standard high-speed steel alternatives.
Designed for use in standard 3/8-inch or larger keyed and keyless drill chucks, including handheld electric drills and bench-mounted drill presses commonly used in mechanical, fabrication, and trade service work.
A licensed or experienced tradesperson should match drill speed to material hardness — slower RPM with steady feed pressure is recommended for hard metals like stainless steel. Always secure the workpiece before drilling to prevent movement. Use cutting fluid on hard metals to reduce heat buildup and extend bit life. Inspect the bit for wear or chipping before each use and replace if the cutting edges are damaged.
