Hertel 85704294 Jobber Drill Bit Wire 52 Hss 118 Degree

Product Description

The HERTEL 85704294 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high-speed steel with a bright uncoated finish, it holds up well in standard shop and field drilling applications. The 118-degree standard point angle is the workhorse geometry used across most general-purpose materials. At wire size 52 (0.0635 inches decimal), this bit fits precision hole requirements where fractional sizes are too coarse. A tapered web with web-thinning reduces thrust and improves chip evacuation on entry. The straight-cylindrical shank seats securely in standard keyless or keyed drill chucks. Overall length is 1-7/8 inches with a 7/8-inch flute length.

This bit suits light-duty production drilling, maintenance and repair work, and precision layout tasks in fabrication shops, HVAC field work, and electrical rough-in where small-diameter pilot or tap-clearance holes are required. The wire gauge sizing is common in tap-drill charts for small-thread fasteners. It is typically used in handheld drills, drill presses, and CNC drilling fixtures that accept a straight-cylindrical shank. The right-hand spiral flute clears chips upward during through-drilling in thin stock and sheet materials.

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in any standard drill chuck or collet accepting a 0.0635-inch straight-cylindrical shank.

Installation Notes

Install in a keyed or keyless drill chuck and tighten fully before operation. Secure workpieces before drilling to prevent movement on breakthrough. Use cutting fluid when drilling hardened steel or stainless to extend bit life. Inspect the cutting edges before each use and replace any bit showing chipping or significant wear to avoid off-size holes.
