Hertel 2385888 Screw Machine Drill Bit 3/16 in Hss

Product Description

The HERTEL 2385888 is a screw machine length drill bit designed for high-speed drilling in metal fabrication, maintenance, and light industrial applications. 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. At 2-3/16 inches overall length with a 1-1/8 inch flute length, the stub-length profile provides added rigidity and control in drill press and hand-held power tool use. Right-hand cutting with a regular spiral flute suits standard clockwise chuck operation.

This drill bit is sized at 3/16 inch (0.1875 inch decimal) and falls within the heavy-duty grade category. It is suited for residential and commercial maintenance work, HVAC sheet metal drilling, electrical rough-in, plumbing bracket mounting, and general trade fabrication tasks. The straight-cylindrical shank fits standard drill chucks without adapters. The web-thinned, parallel web configuration reduces cutting resistance and improves chip clearance in ferrous and non-ferrous materials.

Key Features

• 135-degree split point reduces bit walking and eliminates the need for center punching on most surfaces
• High-speed steel construction with oxide coating for improved lubricity and surface hardness
• Screw machine (stub) length at 2-3/16 inches OAL for enhanced rigidity compared to jobber-length bits
• Web-thinned parallel web lowers thrust requirements and improves chip evacuation
• Right-hand regular spiral flute compatible with standard clockwise drill operation
• Heavy-duty grade rated for repeated use in ferrous and non-ferrous materials

Compatibility

Designed as an OEM-style replacement or direct-use screw machine length drill bit for any standard drill chuck accepting a straight-cylindrical shank in the 3/16 inch size range.

Installation Notes

Installation of this drill bit is performed by HVAC technicians, electricians, plumbers, and general maintenance trades using standard corded or cordless drills and drill presses. Ensure the chuck is fully tightened before operation and that the workpiece is secured to prevent movement. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
