The BSC PREFERRED QJDIB-PTASET-002B is a 13-piece black oxide drill bit set built for general-purpose drilling across a range of materials. The black oxide finish reduces heat buildup during use and adds a layer of corrosion resistance, extending bit life in demanding conditions. Each bit features a 135-degree split-point tip that bites into the work surface immediately, preventing the bit from walking on contact. The set ships with a storage case to keep bits organized and protected between jobs. Weighing approximately 0.64 pounds, the case is compact enough for a tool bag or service van.
This set is suited for trade professionals who need a reliable general-purpose set on the job site. HVAC techs, plumbers, electricians, and general contractors can use these bits for sheet metal, wood, and light-gauge steel drilling tasks that come up during equipment installation, rough-in work, and service calls. The range of sizes from 1/16 inch through 1/4 inch covers the most common pilot holes and clearance holes encountered in residential and light commercial work.
Designed as a general-purpose drill bit set compatible with standard 3/8-inch and 1/2-inch keyed or keyless drill chucks used in cordless and corded drills.
Select the correct bit size for the application before drilling. Secure the workpiece before starting and operate the drill at a speed appropriate for the material being drilled. Inspect bits for wear or damage before each use and replace any bit that shows signs of cracking or excessive dullness. Store bits in the provided case when not in use to prevent damage to cutting edges.
