Bsc Preferred QJDIB-DB-039B Cobalt Drill Bit 9/32 Inch

Product Description

The BSC PREFERRED QJDIB-DB-039B is a cobalt drill bit sized at 9/32 inches, engineered for drilling into hard and abrasive materials where standard high-speed steel bits fail prematurely. The 135-degree split point geometry initiates contact quickly and eliminates bit walking, allowing for accurate hole placement without a center punch. A reinforced core resists torsional stress and breakage under load. This bit is rated for up to nine times the service life of standard black oxide bits, making it a cost-effective choice for fabricators, maintenance mechanics, and trade professionals who regularly work with difficult metals.

The QJDIB-DB-039B is suited for drilling stainless steel, titanium, hardened alloys, and other abrasive ferrous and non-ferrous metals in industrial, commercial, and shop environments. It also performs reliably in wood and PVC, giving it practical utility across mixed-material work. Typical applications include metal fabrication shops, mechanical contractors, and field technicians drilling through structural or schedule pipe components.

Key Features

• 135-degree split point prevents bit walking and enables accurate starts
• Cobalt construction handles hard abrasive materials including stainless steel and titanium
• Reinforced core resists breakage under torsional load
• Up to nine times the lifespan of standard black oxide drill bits
• Compatible with wood and PVC in addition to metal applications
• Sold individually, 9/32 inch diameter

Compatibility

Designed as an OEM-style replacement or direct upgrade for standard 9/32 inch twist drill bit applications in any drill press, handheld power drill, or drill driver accepting round-shank bits of this diameter.

Installation Notes

Use in a drill press or handheld power drill with appropriate RPM for the target material — lower speeds are recommended for harder metals to avoid overheating the cutting edge. Apply cutting fluid or lubricant when drilling stainless steel or titanium to extend bit life and improve cut quality. Secure the workpiece firmly before drilling to prevent movement and ensure accurate hole placement.
