Bsc Preferred QJDIB-BODB-048 Aircraft Drill Bit 3/8 in

Product Description

The BSC PREFERRED QJDIB-BODB-048 is an aircraft-length black oxide drill bit designed for deep-hole drilling applications that require extended reach. At 3/8 inch in diameter and 12 inches in length, this bit handles tough materials including metal, wood, fiberglass, and stainless steel. The 135-degree split point tip self-centers on contact, reducing the need for a center punch and minimizing bit walking. Black oxide coating helps reduce friction and provides moderate corrosion resistance during use. Licensed tradespeople and skilled tradespeople working in tight or deep drilling scenarios will find this bit suited to demanding jobsite conditions.

This aircraft-length drill bit is well suited to applications where standard-length bits cannot reach — including drilling through wall cavities, deep structural members, electrical and plumbing rough-in work, HVAC equipment panels, and fiberglass enclosures. The extended 12-inch shank provides clearance in confined spaces without sacrificing cutting performance. It is sold individually and fits standard 3/8-inch chuck drill drivers and right-angle drills commonly used across electrical, plumbing, HVAC, and general construction trades.

Installation Notes

This bit is installed by trade professionals including electricians, plumbers, HVAC technicians, and general contractors. Secure the bit fully into the chuck before operation and verify chuck tightness. When drilling metal or stainless steel, use appropriate cutting fluid to extend bit life and reduce heat buildup. Always wear eye protection and follow applicable jobsite safety requirements.
