Triumph Twist Drill 011504 Cobalt Drill Bit 1/16 in

Product Description

The TRIUMPH TWIST DRILL 011504 is a cobalt jobber length drill bit designed for high-performance drilling in tough materials. Built from cobalt with a gold oxide coating, it delivers increased heat and wear resistance compared to standard high-speed steel bits. The 135-degree split point promotes self-centering on contact, reducing the need for a center punch and minimizing walking on hard surfaces. With a straight-cylindrical shank and right-hand spiral flute, it is suited for use in standard drill chucks across a range of stationary and handheld equipment. This bit is rated for heavy-duty use by trade professionals working with alloy and alloy steel workpieces.

The 011504 is intended for drilling alloy and alloy steel in demanding trade applications including mechanical, HVAC fabrication, plumbing rough-in, and electrical panel work where harder fastener materials and structural steel are common. The 1/16 inch diameter and 1-7/8 inch overall length make it appropriate for tight-clearance work and small-diameter hole requirements. The web-thinned, tapered web configuration reduces thrust and improves chip evacuation during regular spiral drilling operations. This bit ships individually but carries a minimum order quantity of 12 units.

Key Features

• Cobalt construction with gold oxide coating for heat resistance and extended tool life in hard metals
• 135-degree split point for self-centering entry without a center punch
• Web-thinned tapered web reduces cutting thrust and improves chip clearance
• Right-hand cut with regular spiral flute for efficient material removal
• Straight-cylindrical shank fits standard drill chucks without modification
• Heavy-duty grade rated for alloy and alloy steel workpiece materials

Compatibility

Designed for use with alloy and alloy steel workpiece materials; fits standard straight-shank drill chucks accepting a 1/16 inch shank diameter. Series T1C jobber length format.

Installation Notes

This bit is installed and operated by machinists, pipefitters, electricians, and HVAC sheet metal technicians using standard drill presses or handheld power drills. Ensure the workpiece is secured before drilling and that the chuck is fully tightened on the straight-cylindrical shank. Coolant-through operation is not supported on this bit; use appropriate cutting fluid applied externally when drilling hard alloy steels to manage heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or wear is observed.
