Hertel 2386332 Screw Machine Drill Bit Size 26 Hss

Product Description

The HERTEL 2386332 is a screw machine length drill bit designed for high-production drilling in metal, plastic, and similar materials. Built from high-speed steel with an oxide coating, this bit runs in right-hand rotation with a regular spiral flute and a 135-degree split point. The split point geometry reduces walking at entry and lowers the thrust needed to initiate the cut, making it well-suited for use in drill presses, CNC machines, turret lathes, and automatic screw machines. The straight-cylindrical shank measures 0.147 inches in diameter, compatible with standard drill chucks. Overall length is 2-1/16 inches with a 1-inch flute length.

This bit is sized to wire gauge No. 26, equivalent to 0.147 inches decimal, placing it in the 0.100 to 0.150 inch diameter range. The screw machine length body is shorter than jobber-length bits, which increases rigidity and reduces deflection in tight setups or gang-drilling fixtures. It is a common choice for machinists, tool-and-die workers, and production shop technicians working with small-diameter through-holes on metal components. The oxide finish provides light corrosion resistance and modest lubrication retention during cutting.

Key Features

• 135-degree split point reduces bit walking and lowers entry thrust
• High-speed steel construction handles standard metal cutting applications
• Oxide coating adds corrosion resistance and helps retain cutting fluid
• Screw machine length body increases rigidity versus jobber-length bits
• Web-thinned parallel web supports clean chip evacuation in spiral flute
• Right-hand cutting, straight-cylindrical shank fits standard chucks

Compatibility

Designed as a direct-fit replacement for standard wire gauge No. 26 screw machine length drill bits used in drill presses, CNC lathes, turret machines, and automatic screw machine setups requiring a straight-cylindrical shank.

Installation Notes

This bit is installed and serviced by machinists and production tooling technicians. Secure the shank fully in the chuck and verify runout before beginning a drilling cycle. Power down and lock out the machine before changing bits. Do not exceed the material and speed ratings appropriate for high-speed steel tooling in the material being cut.
