Hertel 2386456 Screw Machine Drill Bit Size 38 Hss

Product Description

The HERTEL 2386456 is a screw machine length drill bit designed for high-speed drilling in metal, plastic, and other common shop materials. Built from high-speed steel with an oxide coating for added lubricity and wear resistance, this bit carries a wire gauge size of 38, equivalent to 0.1015 inch decimal diameter. The 135-degree split point reduces walking on entry and minimizes the need for a center punch, improving hole placement accuracy. At 1-13/16 inches overall length, the screw machine format provides added rigidity over jobber-length bits, making it well suited for close-quarter drilling in CNC machines, screw machines, and manual drill presses.

This bit is intended for production machining environments and general metalworking applications where a shorter, stiffer bit is required to maintain accuracy and reduce chatter. The straight-cylindrical shank fits standard drill chucks without modification. The regular spiral flute design promotes efficient chip evacuation during drilling. Licensed machinists, tool-and-die technicians, and general maintenance tradespeople will find this bit appropriate for repetitive, precision drilling tasks in production or maintenance settings.

Key Features

• Wire gauge size 38, 0.1015 inch decimal diameter for precise hole sizing
• 135-degree split point reduces walking and decreases entry force required
• High-speed steel construction withstands elevated cutting temperatures
• Oxide coating improves lubricity and extends tool life in ferrous materials
• Screw machine length body provides greater rigidity than jobber-length bits
• Web-thinned, parallel web configuration reduces thrust load during drilling

Compatibility

Designed as an OEM-style replacement or production consumable for standard drill chucks accepting a 0.1015 inch straight-cylindrical shank, compatible with CNC drilling stations, screw machines, and benchtop drill presses configured for wire gauge tooling.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Ensure the drilling machine is fully powered down and the chuck is fully released before inserting or removing the bit. Secure the shank firmly in the chuck to the full depth of the chuck jaws to minimize runout and prevent slippage during cutting. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed selection based on material and bit diameter.
