Hertel C.40W.1508 Taper Length Drill 19/32 Hss

Product Description

The HERTEL C.40W.1508 is a taper length high-speed steel drill bit with a 19/32 inch (0.5938 inch) diameter and a standard 118-degree split point. Built from HSS with a black oxide finish, it is designed for drilling through ferrous metals, structural steel, and general fabrication materials. The taper length body provides greater reach than a jobber-length bit without sacrificing rigidity, making it a practical choice for deep-hole work in metal fabrication shops, mechanical contractors, and industrial maintenance settings. Web thinning reduces entry force and improves chip clearing in harder materials.

This bit is suited for use with floor-mounted drill presses, magnetic base drills, and heavy-duty hand drills in industrial and commercial applications. The straight cylindrical shank fits standard drill chucks without adapters. Typical install scenarios include structural steel fabrication, pipe fitting layout work, HVAC bracket drilling, and general mechanical maintenance where a longer reach is needed beyond what a standard jobber bit provides.

Key Features

• 19/32 inch (0.5938 inch) diameter with matching straight cylindrical shank for secure chuck grip
• 118-degree standard point angle suited for general-purpose metal drilling
• Taper length body at 8.75 inches overall for extended reach applications
• HSS construction with black oxide finish for improved lubricity and basic corrosion resistance
• Right-hand spiral flute with regular helix for efficient chip evacuation
• Web-thinned tapered web reduces thrust force at entry

Compatibility

Designed as a standard taper length drill bit for use in any drill press or hand drill equipped with a chuck that accepts a straight cylindrical shank up to 19/32 inch diameter.

Installation Notes

Install and removal should be performed with the drill press or tool fully powered down and the chuck key removed before changing bits. Secure the workpiece with a vise or clamps before drilling to prevent rotation. Use appropriate cutting fluid for ferrous metals to extend bit life and improve hole quality. A licensed machinist or qualified tradesperson should verify feed rate and speed settings appropriate for the material being drilled.
