The BSC PREFERRED QJDIB-DB-005 is a 1/8-inch titanium-coated twist drill bit sold in a two-pack. The titanium coating reduces heat buildup during drilling, extending cutting life up to three times longer than standard black oxide bits. A 135-degree split point tip allows the bit to start on contact without walking, eliminating the need for a center punch on most materials. The stronger core design resists breakage under load. These bits are suited for use by HVAC technicians, electricians, plumbers, and general tradespeople who drill frequently into mixed materials on the job.
The QJDIB-DB-005 is a multipurpose bit appropriate for drilling into steel, wood, and PVC. Common applications include mounting brackets, running conduit, installing pipe hangers, and general fabrication tasks. The 1/8-inch diameter is a standard pilot hole and clearance hole size used across plumbing, electrical, and HVAC rough-in work. Sold as a two-pack, making it practical to keep a spare on hand during active service calls.
Designed for use in standard 3-jaw keyed or keyless drill chucks accepting 1/8-inch round shanks, compatible with corded and cordless drills commonly used in trade applications.
Secure the workpiece before drilling to prevent movement. Use appropriate drill speed for the material being drilled - lower speeds for steel, higher speeds for wood and PVC. Wear eye protection per standard job site safety requirements. Inspect the bit tip before each use and replace if the cutting edges show signs of wear or chipping.
