Bsc Preferred QJDIB-DB-020 Black Oxide Drill Bit 7/64

Product Description

The BSC PREFERRED QJDIB-DB-020 is a 7/64 inch black oxide drill bit precision-ground from high-speed steel and sold in a 2-pack. The black oxide coating provides corrosion resistance and helps reduce friction during drilling operations. A 135-degree split point eliminates bit walking for accurate hole starts without center-punching. The reinforced core increases resistance to breakage under load, making this bit a reliable choice for general-purpose drilling tasks across metal, wood, and plastic substrates. Licensed tradespeople and skilled DIYers will find this bit suited for everyday jobsite and workshop use.

This drill bit is designed for general-purpose drilling applications including angle iron, wood, and PVC. The 7/64 inch diameter is commonly used for pilot holes, light metalwork, and fastener preparation. Packaged as a 2-pack on a card, this format is practical for field technicians and service professionals who need a reliable spare on hand. The high-speed steel construction holds an edge through repeated use across a variety of common materials encountered in HVAC, plumbing, and electrical rough-in work.

Installation Notes

Installation is performed by any trade professional or skilled DIYer using a standard corded or cordless drill. Secure the bit firmly in the chuck before drilling and confirm the workpiece is clamped or otherwise stabilized. For metal substrates, use appropriate cutting fluid to extend bit life and reduce heat buildup. Disconnect power to any electrical components in the work area before drilling near live circuits per NEC guidelines.
