Bsc Preferred QJDIB-DB-013 Titanium Drill Bit 5/16 Inch

Product Description

The BSC PREFERRED QJDIB-DB-013 is a 5/16-inch titanium-coated twist drill bit designed for fast, accurate drilling across a range of common trade materials. The titanium nitride coating reduces heat buildup during use, which helps the cutting edge stay sharper longer compared to standard black oxide bits. A 135-degree split point tip allows the bit to engage the workpiece immediately without walking or requiring a center punch. The stronger core construction resists bit breakage under load, making this a reliable choice for repetitive drilling tasks on the job.

This drill bit is suited for use in metal fabrication, plumbing rough-in, electrical work, and general construction applications. It performs in steel, wood, and PVC, covering the materials most commonly encountered by HVAC technicians, plumbers, electricians, and general contractors. The 5/16-inch diameter is a frequently used size for conduit anchors, pipe hangers, and structural fastener clearance holes.

Key Features

• Titanium nitride coating reduces heat buildup and extends cutting life up to 3x longer than black oxide bits
• 135-degree split point tip prevents walking for accurate hole placement without a center punch
• Reinforced core resists breakage under drilling load
• 5/16-inch diameter suits common trade fastener and anchor applications
• Compatible with standard 3-jaw drill chucks found on corded and cordless drills

Compatibility

Designed as a general-purpose replacement or supplemental drill bit for use in standard 3-jaw drill chucks. Suitable for drilling steel, wood, and PVC in residential and light commercial trade applications.

Installation Notes

Install in a standard drill chuck and tighten securely with a chuck key or by hand-tightening a keyless chuck before use. Reduce feed pressure when breaking through the back side of the material to avoid grabbing or bit deflection. Wear appropriate eye protection when drilling metal. Follow applicable safety codes and employer guidelines when working with power tools on the jobsite.
