Hertel 84023852 Stub Drill Bit No. 10 135 Split Point

Product Description

The HERTEL 84023852 is a stub-length threaded shank drill bit designed for precision drilling in low-tensile strength materials. Built from high speed steel with an oxide coating, this bit features a 135-degree split point that reduces walking and requires no center punch on most surfaces. The No. 10 wire size corresponds to a 0.1935-inch decimal diameter. The 1/4-28 threaded hex shank provides a secure, concentric connection in compatible tooling systems. At 0.5625 inches overall length, this stub-length bit maximizes rigidity and minimizes deflection in tight-clearance applications. Licensed HVAC techs, plumbers, electricians, and general trade professionals use stub drill bits where standard-length bits would flex or lack clearance.

This bit is suited for drilling in aluminum, soft steel, plastic, and other low-tensile strength materials common in light fabrication, panel work, and equipment installation. The 5/16-inch flute length and tapered web configuration support efficient chip evacuation in short-stroke drilling. The right-hand spiral flute and web-thinned point reduce cutting resistance and heat buildup. The 1/4-28 threaded shank is designed for use with threaded-shank toolholders and compatible quick-change systems that accept this shank standard.

Key Features

• 135-degree split point reduces walking and improves entry accuracy without a center punch

• Stub-length body at 0.5625 inches OAL maximizes rigidity in confined spaces
• 1/4-28 threaded hex shank for secure, concentric seating in compatible toolholders
• Web-thinned, tapered web design reduces thrust and cutting load
• Right-hand spiral flute with regular helix for consistent chip removal

Compatibility

Designed for use with threaded-shank toolholders accepting a 1/4-28 thread. Meets NAS 965 Type B specification. Intended for low-tensile strength material applications in general-purpose trade use.

Installation Notes

Installation and use of this bit should be performed by qualified trade professionals familiar with drill press, hand drill, or air tool operation. Ensure the threaded shank is fully seated and torqued into the toolholder before operation. Always verify the workpiece is secured before drilling. Use appropriate eye protection and follow applicable shop safety standards.
