Hertel 53384269 Threaded Shank Drill Bit 0.246 in Cobalt

Product Description

The HERTEL 53384269 is a threaded shank drill bit designed for precision drilling in metal and hard materials. Built from cobalt with an oxide coating, this bit delivers heat resistance and extended wear life in demanding drilling applications. It features a 135-degree standard point angle that reduces walking on entry and requires less thrust than a 118-degree point. The 1/4-28 threaded shank provides secure, positive engagement in compatible toolholders. The overall length is 2.125 inches with a flute length of 1.25 inches. This bit is typically installed by machinists, maintenance technicians, and trade professionals working in metal fabrication, HVAC equipment assembly, or mechanical service environments.

This drill bit is suited for use in ferrous metals, stainless steel, and other hard materials where cobalt-grade tooling is required. The 0.246-inch diameter and threaded 1/4-28 shank make it appropriate for close-tolerance drilling tasks in both production and field repair settings. The spiral flute geometry promotes chip evacuation during through-hole and blind-hole operations. It ships individually and is sold as a single unit.

Key Features

• Cobalt construction with oxide coating for heat resistance and extended tool life
• 135-degree standard point angle reduces bit walking and lowers required drilling thrust
• 1/4-28 threaded shank for positive, repeatable engagement in compatible holders
• Regular spiral flute promotes efficient chip evacuation
• 0.246-inch diameter suitable for close-tolerance hole applications
• No coolant-through design — standard dry or cutting-fluid-assisted drilling

Compatibility

Designed for use with toolholders and drill chucks accepting a 1/4-28 threaded shank. Consult your toolholder manufacturer specifications to confirm thread engagement compatibility before use.

Installation Notes

Installation and use should be performed by qualified machinists or trade technicians familiar with rotating cutting tools. Secure the bit fully into the threaded holder to the manufacturer-specified engagement depth before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Do not exceed the recommended RPM range for cobalt tooling in the material being drilled.
