Hertel 2386001 Screw Machine Drill Bit 3/8 in Hss

Product Description

The HERTEL 2386001 is a screw machine length drill bit designed for high-production drilling in metal, steel, and similar materials. Built from heavy-duty high-speed steel with an oxide finish, it runs a 135-degree split point that reduces walking and cutting pressure at startup. The straight-cylindrical shank seats securely in standard drill chucks. At 3-1/8 inches overall length with a 1-13/16 inch flute length, it fits short-chuck setups and turret lathes common in screw machine and CNC lathe work. Web thinning further reduces thrust load, making it a practical choice for production environments where cycle time and tool life matter.

This bit is suited for screw machine work, turret lathe setups, and general production drilling where a shorter overall length gives better rigidity and reduces deflection. The right-hand spiral flute clears chips efficiently in through-hole and blind-hole applications. It is typically installed by machinists, tool-and-die workers, and maintenance technicians working on metalworking equipment. The oxide coating provides a moderate level of lubricity and corrosion resistance during storage and use.

Key Features

• 135-degree split point reduces drill walking and lowers cutting pressure at entry
• Heavy-duty high-speed steel construction rated for production drilling cycles
• Web-thinned parallel web reduces axial thrust load
• Oxide coating adds surface lubricity and corrosion resistance
• Screw machine length at 3-1/8 inches overall for improved rigidity in short-chuck setups
• Straight-cylindrical shank fits standard drill chucks and collets

Compatibility

Designed as a screw machine length replacement drill bit for use in standard drill chucks, turret lathes, screw machines, and CNC lathes accepting a 3/8 inch straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians. Secure the shank fully in the chuck or collet and verify runout before engaging the workpiece. Power down and lock out the machine before changing or inspecting the bit. Follow shop safety standards for eye protection and chip clearance when drilling ferrous materials.
