Bsc Preferred QJDIB-DB-036A Cobalt Drill Bit 11/64 Inch

Product Description

The BSC PREFERRED QJDIB-DB-036A is an 11/64-inch cobalt drill bit engineered for industrial and trade use in hard, abrasive materials. The 135-degree split point tip penetrates quickly and prevents the bit from walking on smooth or curved surfaces, producing accurate hole starts without a center punch. A reinforced core resists torsional stress and breakage under heavy drilling loads. This bit is suited for machinists, maintenance techs, fabricators, and trade professionals working with demanding materials on a regular basis.

The QJDIB-DB-036A is designed for drilling stainless steel, titanium, hardened alloys, and similarly abrasive metals. It also performs reliably in wood and PVC, making it a versatile option for multi-trade shops and service vans. The cobalt steel construction provides a significant service life advantage over standard black oxide bits, with up to 9 times the lifespan under comparable conditions. It is well suited to hand-held drill applications as well as drill press setups.

Key Features

• 135-degree split point prevents walking and enables accurate, self-starting hole placement
• Cobalt steel construction rated for stainless steel, titanium, and other hard abrasive materials
• Reinforced core resists breakage under high-torque or heavy-feed drilling conditions
• Up to 9 times the service life of standard black oxide drill bits
• Compatible with wood and PVC in addition to metals, supporting multi-material use

Compatibility

Designed as an OEM-style replacement and general-purpose cobalt drill bit for 11/64-inch applications across industrial, HVAC, plumbing, electrical, and general trade work where hard-material drilling is required.

Installation Notes

Use in a drill press or hand-held drill with appropriate RPM for the material being drilled — lower speeds are recommended for hard metals such as stainless steel to prevent overheating. Apply cutting oil or coolant when drilling ferrous metals to extend bit life and maintain dimensional accuracy. Secure the workpiece firmly before drilling to reduce vibration and bit deflection. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed.
