Bsc Preferred QJDIB-BODB-045 Aircraft Drill Bit 3/16 in

Product Description

The BSC PREFERRED QJDIB-BODB-045 is an aircraft-length black oxide drill bit built for deep hole drilling applications that demand extra reach. At 3/16 inch in diameter and 12 inches in overall length, this bit handles tough materials including metal, wood, fiberglass, and stainless steel. The 135-degree split point tip promotes accurate self-starting penetration and reduces bit walking at the point of entry. Black oxide finish provides mild corrosion resistance and reduces friction during drilling. Licensed tradespeople and experienced DIYers working on structural, mechanical, or fabrication tasks will find this bit suited for hard-to-reach bore locations where standard-length bits fall short.

Aircraft-length drill bits are used across HVAC, electrical, plumbing, and general fabrication trades wherever deep or extended-reach holes are required. Common applications include drilling through deep wall cavities, structural members, stacked panels, and equipment enclosures. The 3/16 inch diameter is a standard size for pilot holes, conduit anchor points, sheet metal work, and through-hole fastener applications. This bit is sold individually and is compatible with any standard drill chuck accepting 3/16 inch shank tooling.

Key Features

• 135-degree split point tip reduces walking and improves hole accuracy on hard surfaces
• 12 inch aircraft length provides extended reach into deep cavities and structural assemblies
• 3/16 inch diameter suits pilot holes, sheet metal, and light structural applications
• Black oxide finish reduces friction and provides mild corrosion resistance
• Compatible with metal, wood, fiberglass, and stainless steel workpieces

Compatibility

Designed for use with any standard drill or drill press accepting a 3/16 inch round shank bit. Suitable for hand drills, right-angle drills, and drill presses commonly used in HVAC, plumbing, electrical, and fabrication applications.

Installation Notes

Aircraft-length bits are more susceptible to deflection than jobber-length bits; use moderate feed pressure and reduce speed when drilling harder materials to maintain accuracy. Secure the workpiece firmly before drilling to prevent movement. When drilling stainless steel or hardened metals, use cutting fluid to extend bit life and reduce heat buildup. Inspect the bit tip for wear before each use and replace if the cutting edges are chipped or dulled.
