Hertel 2386415 Screw Machine Drill Bit Size 34 Hss

Product Description

The HERTEL 2386415 is a screw machine length drill bit designed for high-speed, close-tolerance drilling in metal fabrication, machining, and production environments. Built from high-speed steel with an oxide coating, it features a 135-degree split point that reduces walking and requires no center punch on most materials. The web-thinned, parallel web construction reduces thrust and improves chip evacuation. At 1.875 inches overall length with a 0.875-inch flute, this stub-length geometry provides added rigidity over jobber-length bits, making it well suited for CNC turrets, drill presses, and hand-held power tools in production runs. Machinists, tool-and-die technicians, and maintenance mechanics are the typical end users.

This bit is intended for drilling in ferrous and non-ferrous metals, plastics, and composite materials where a compact cutting tool is required. The Size 34 wire gauge corresponds to a decimal diameter of 0.1110 inches, placing it in the 0.1000 to 0.1500 inch drill bit size range. It is well matched to tapping operations requiring a close pilot hole, sheet metal work, and production drilling where consistent hole quality and bit rigidity matter. The straight-cylindrical shank seats in standard drill chucks and collet holders without modification.

Key Features

• 135-degree split point reduces bit walking and cutting thrust
• Web-thinned, parallel web construction improves chip flow and reduces heat buildup
• High-speed steel construction with oxide finish for corrosion resistance and lubricity
• Screw machine (stub) length provides greater rigidity than jobber-length bits
• Right-hand, regular spiral flute for standard drilling applications
• Straight-cylindrical shank compatible with standard drill chucks and collet systems

Compatibility

Designed as an OEM-style replacement or standard tooling option for any drill press, CNC turret, or hand-held power tool accepting a straight-cylindrical shank bit with a 0.1110-inch diameter.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians. Secure the shank fully in the chuck or collet and verify concentricity before drilling. Power down and de-energize the machine spindle completely before changing bits. Do not exceed the recommended feed and speed range for the workpiece material, and use appropriate cutting fluid when drilling ferrous metals to prolong tool life.
