Hertel 2385805 Screw Machine Drill Bit Size 10 Hss Tin

Product Description

The HERTEL 2385805 is a screw machine length drill bit designed for high-speed steel cutting applications where a shorter, more rigid tool is preferred over a jobber-length bit. Sized to wire gauge #10 (0.1935 inches decimal equivalent), it features a 135-degree split point that reduces walking and requires no center punch on most materials. The titanium nitride (TiN) coating increases surface hardness and extends tool life in production drilling environments. With an overall length of 2.25 inches and a flute length of 1.1875 inches, this bit fits standard drill chucks and CNC toolholders via its straight-cylindrical shank. Right-hand cut with a regular spiral flute configuration. Installed by machinists, maintenance technicians, and fabricators.

Screw machine length drill bits are used in close-quarters drilling, drill press work, turret lathes, and CNC machining centers where reduced overhang improves rigidity and accuracy. The shorter body minimizes deflection when drilling through steel, aluminum, plastics, and similar materials at production rates. The web-thinned, parallel-web construction reduces thrust and improves chip evacuation. This bit is appropriate for both manual and CNC-driven applications in light manufacturing, maintenance, and repair operations.

Key Features

• Wire gauge #10 size, 0.1935 inches decimal equivalent
• 135-degree split point reduces bit walking and lowers required thrust
• TiN coating increases surface hardness and extends service life
• Screw machine length body (2.25 inches OAL) provides greater rigidity than jobber-length bits
• Web-thinned parallel web improves chip evacuation and reduces heat buildup
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed for use in standard drill chucks, collet holders, and CNC toolholders accepting a straight-cylindrical shank within the 0.1500 to 0.2000 inch drill bit size range.

Installation Notes

Secure the shank fully in the chuck or collet before use and confirm runout is within acceptable limits for the application. Always power down and de-energize the machine spindle before changing tooling. Use appropriate cutting fluid or coolant for the workpiece material to preserve coating life, noting this bit does not support through-coolant. Follow applicable shop safety and machine guarding procedures during setup and operation.
