Bsc Preferred QJDIB-DB-035A Cobalt Drill Bit 9/64 Inch

Product Description

The BSC PREFERRED QJDIB-DB-035A is a 9/64-inch cobalt drill bit built for industrial-grade performance in hard and abrasive materials. The 135-degree split point design allows fast penetration and prevents bit walking, giving technicians and tradespeople accurate, clean starts without center-punching. The stronger core construction resists breakage under load. Compared to standard black oxide bits, this cobalt bit is rated for up to nine times the service life, making it a cost-effective choice for high-volume or demanding drilling applications. It is suitable for use on metals including stainless steel and titanium, as well as wood and PVC.

This bit fits standard drilling applications across mechanical, plumbing, electrical, and general trade work. Its durability makes it well suited for repetitive drilling in fabrication shops, field service, and maintenance environments where hard or abrasive materials are encountered regularly. The 9/64-inch diameter is a common size for pilot holes, clearance holes, and tap-prep work in light to medium gauge metal.

Key Features

• 135-degree split point prevents walking and enables self-starting entry
• Cobalt construction handles stainless steel, titanium, and other hard abrasive materials
• Stronger core resists breakage during high-load drilling
• Rated for up to nine times the lifespan of standard black oxide bits
• Multi-material capable: metals, wood, and PVC

Compatibility

Designed for use in standard 3/8-inch or 1/2-inch keyed and keyless drill chucks compatible with round-shank drill bits at 9/64-inch diameter.

Installation Notes

Secure the workpiece before drilling to prevent movement. Use cutting fluid or lubricant when drilling stainless steel or titanium to reduce heat buildup and extend bit life. Start at a lower RPM on hard metals and increase speed as needed. Inspect the bit regularly for signs of wear or heat damage and replace before the cutting edge degrades.
