Hertel 84578186 Jobber Drill Bit Wire 63 Hss 118

Product Description

The HERTEL 84578186 is a jobber-length drill bit sized to wire gauge 63, equivalent to 0.0370 inches in decimal. Built from high speed steel with a bright, uncoated finish, it is designed for general-purpose drilling in metal, wood, and plastic. The standard 118-degree split point promotes accurate entry and reduces walking on flat surfaces. At 1.5 inches overall length with a 0.625-inch flute, this bit suits compact drilling applications where clearance is tight. A two-flute spiral design with regular helix and web-thinned, tapered web construction helps clear chips efficiently without recutting. Straight-cylindrical shank fits standard drill chucks. This bit is sold individually but must be ordered in multiples of 12.

This jobber-length drill bit is suited for light-duty production drilling, maintenance and repair operations, and precision pilot hole applications across metalworking, HVAC sheet metal fabrication, plumbing rough-in, and electrical trade work. The wire gauge 63 size is commonly used when a closely toleranced small-diameter hole is required before tapping or reaming. Its compact overall length makes it practical for use in tight workspaces encountered in field service and panel work.

Key Features

• Wire gauge 63 size — 0.0370-inch decimal diameter for close-tolerance small-hole work
• 118-degree standard point angle with web-thinned, tapered web for clean entry
• High speed steel construction rated for general-purpose use across common workpiece materials
• Two-flute regular spiral design promotes chip evacuation in short, blind, and through holes
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Bright uncoated finish — no coating to chip or flake during regrinding

Compatibility

Designed as an OEM-style general-purpose jobber drill bit compatible with any standard drill chuck or collet accepting a 0.0370-inch straight-cylindrical shank.

Installation Notes

This bit is installed by a machinist, HVAC fabricator, electrician, or plumber using a standard handheld, bench, or drill press chuck. Secure the straight shank firmly before applying feed pressure to prevent slippage and bit breakage at this small diameter. Use appropriate cutting fluid or lubricant when drilling steel or stainless to extend bit life. At 0.0370-inch diameter, excessive lateral force will snap the bit — maintain consistent, controlled feed rate.
