Hertel 2386068 Screw Machine Drill Bit 15/32 in Hss

Product Description

The HERTEL 2386068 is a screw machine length drill bit designed for high-production drilling in metal fabrication, maintenance, and mechanical trade work. Built from high-speed steel with an oxide coating, it features a 135-degree split point and web-thinned geometry that reduces thrust and improves chip evacuation on entry. The 15/32-inch diameter (0.4688 inches decimal) and shortened overall length of 3-5/8 inches make it well suited for use in drill presses, lathes, and CNC equipment where rigid, close-tolerance drilling is required. Right-hand spiral flutes and a straight cylindrical shank round out the design for reliable performance in heavy-duty applications.

This bit fits into workflows where a standard jobber-length drill would be too flexible or prone to deflection. The screw machine format provides added rigidity in tight setups. Typical applications include repetitive hole drilling in steel, cast iron, aluminum, and similar materials on production floors, in machine shops, and during mechanical service work. The heavy-duty grade designation indicates suitability for higher feed rates and more demanding cycle times than general-purpose bits.

Key Features

• 15/32-inch diameter (0.4688 inches decimal) with screw machine length for added rigidity
• 135-degree split point reduces walking and decreases entry thrust
• Web-thinned, parallel web construction improves chip flow and cutting efficiency
• High-speed steel construction with oxide coating for heat and wear resistance
• Right-hand spiral flute, straight cylindrical shank for standard chuck compatibility
• Heavy-duty grade rated for higher feed rates and production drilling cycles

Compatibility

Designed as a direct-fit screw machine length drill bit for any standard drill press, lathe tailstock, or CNC spindle accepting a straight cylindrical shank in the 15/32-inch size range.

Installation Notes

Installation and operation should be performed by a qualified machinist or mechanical trade professional. Secure the shank fully in the chuck or collet and verify runout before drilling. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before starting the spindle. Do not exceed the recommended feed and speed range for the workpiece material to avoid premature tool wear or bit breakage.
