Titan Usa CD42850 Jobber Drill Bit 8.50mm Hss

Product Description

The TITAN USA CD42850 is a high speed steel jobber-length drill bit sized at 8.50mm (0.3346 inches) diameter. It features a 118-degree standard point angle and a black oxide coating that reduces friction and provides basic corrosion resistance during cutting operations. The spiral flute geometry promotes chip evacuation in a right-hand cutting direction. With an overall length of 121mm (4.7674 inches) and a flute length of 87mm (3.4278 inches), this bit handles general-purpose through-hole and deep drilling applications. It is sold individually and suited for use in drill presses, hand drills, and CNC setups by machinists, maintenance technicians, and trade professionals.

The CD42850 is designed for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard straight-shank drill chucks with a shank diameter of 0.3346 inches. The regular spiral type and two-flute configuration make it a practical choice for production and maintenance drilling tasks across metal fabrication, HVAC equipment repair, plumbing rough-in work, and general mechanical service where consistent hole quality in metal workpieces is required.

• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style replacement and general-use jobber drill bit for straight-shank drill chucks compatible with 0.3346-inch shank diameter tooling across drill presses, hand drills, and CNC equipment.

Installation Notes

This bit is installed by licensed machinists and trade technicians using standard drill chuck equipment. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to manage heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
