Hertel 2387256 Screw Machine Drill Bit Size 6 Tin Hss

Product Description

The HERTEL 2387256 is a screw machine length drill bit designed for high-speed drilling in metal fabrication, machining, and general shop applications. It is manufactured from high-speed steel (HSS) with a titanium nitride (TiN) coating that extends tool life and reduces friction during cutting. The bit features a 135-degree split point for reduced walking on entry and faster penetration without a center punch. At 2.375 inches overall length, the stub-length body provides added rigidity in tight clearance situations, making it a practical choice for production drilling and repair work.

This bit is suited for use in screw machine operations, drill presses, CNC machining centers, and hand-held power drills where a compact, rigid drill is required. The 0.2040 inch decimal diameter corresponds to a Number 6 wire gauge size, placing it in the 0.2000 to 0.2500 inch diameter range. It is commonly used by machinists and maintenance mechanics drilling mild steel, aluminum, and similar materials where a TiN-coated HSS tool is appropriate. Right-hand cutting direction is standard for conventional drill press and machine spindle rotation.

Key Features

• 135-degree split point reduces drill walking and lowers thrust required at entry
• TiN coating improves surface hardness and extends cutting edge life compared to uncoated HSS
• Screw machine (stub) length body at 2.375 inches OAL increases rigidity in close-clearance setups
• Web-thinned parallel web construction reduces cutting resistance through the chisel edge
• Straight-cylindrical shank fits standard drill chucks without adapters
• Regular spiral flute with 1.25 inch flute length for efficient chip evacuation at this diameter

Compatibility

Designed as a standard Number 6 wire gauge screw machine length drill bit compatible with any drill press, CNC spindle, or hand drill chuck accepting a 0.2040 inch straight-cylindrical shank.

Installation Notes

Installation and use of this bit is performed by machinists or maintenance mechanics operating drill presses or power tools. Ensure the drill chuck is fully tightened and the workpiece is securely clamped or fixtured before beginning the cut. Use appropriate cutting fluid or coolant for the material being drilled to preserve the TiN coating and extend tool life. Inspect the cutting edges for wear before each use and replace the bit if chipping or excessive dulling is observed.
