Hertel 66694134 Jobber Drill Bit Wire 14 Hss Tin 135 Deg

Product Description

The HERTEL 66694134 is a wire size 14 jobber-length drill bit designed for precision holemaking in metal, plastic, and composite materials. Built from heavy-duty high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during drilling. The 135-degree split point starts on contact without center-punching and reduces walking on hard or smooth surfaces. At 3-3/8 inches overall length with a 2-3/16-inch flute length, it fits standard drill chucks and drill presses used in machine shops, fabrication, and maintenance work. Right-hand spiral flutes clear chips efficiently during through-hole and blind-hole operations.

This drill bit suits a wide range of holemaking applications in metal fabrication, general machining, HVAC sheet metal work, electrical rough-in, and plumbing rough-in where wire gauge sized holes are required. The 0.1820-inch decimal diameter corresponds to wire size 14 and is commonly used when precise hole sizing is needed for tapping, reaming, or clearance fits. The straight-cylindrical shank seats securely in keyless and keyed chucks alike, making it compatible with handheld drills, drill presses, and CNC machining centers.

Key Features

• 135-degree split point reduces thrust and eliminates walking on startup
• TiN coating extends surface hardness and reduces heat buildup at the cutting edge
• Heavy-duty high speed steel construction rated for demanding production use
• Web-thinned, tapered web design lowers cutting resistance in harder materials
• Right-hand, regular spiral flutes with 2-flute configuration for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a jobber-length replacement drill bit for applications requiring a 0.1820-inch (wire size 14) hole diameter, compatible with any drill press, hand drill, or CNC spindle accepting a straight-cylindrical 0.1820-inch shank.

Installation Notes

Install in a properly sized chuck and tighten securely before operation. Use cutting fluid or coolant appropriate to the workpiece material to maximize tool life, particularly when drilling steel or stainless. Secure the workpiece firmly before drilling to prevent rotation. Follow applicable shop safety standards and wear appropriate eye protection at all times.
