Hertel 2386209 Screw Machine Drill Bit Size 13 Hss

Product Description

The HERTEL 2386209 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 finish, this bit measures 0.185 inches in diameter (wire size 13) with an overall length of 2.1875 inches. The 135-degree split point reduces walking and cutting pressure at entry, making it well suited for drilling into steel, aluminum, and other ferrous and non-ferrous metals. The web-thinned, parallel web construction further reduces thrust load. Right-hand spiral flutes evacuate chips efficiently during drilling operations. Licensed machinists, tool-and-die makers, and maintenance mechanics are the primary users.

The HERTEL 2386209 is used in screw machine shops, production machining cells, and maintenance repair operations where a shorter, stiffer bit is needed to minimize deflection. The stubby screw machine length geometry provides added rigidity compared to jobber-length bits, making it a preferred choice for high-speed CNC drilling, turret lathes, and automatic screw machines. It is appropriate for drilling through mild steel, cast iron, aluminum, brass, and similar materials at standard production feeds and speeds.

Key Features

• Wire size 13 diameter at 0.185 inches for precision sizing
• 135-degree split point reduces entry walking and lowers required thrust
• Web-thinned parallel web for reduced cutting resistance
• High-speed steel construction with oxide coating for corrosion resistance and lubricity
• Screw machine length at 2.1875 inches overall for improved rigidity over jobber-length bits
• Right-hand spiral flute for efficient chip evacuation

Compatibility

Designed as a screw machine length replacement drill bit suitable for wire size 13 applications falling within the 0.150 to 0.200 inch decimal range, compatible with standard straight-cylindrical shank tool holders and drill chucks accepting a 0.185-inch shank.

Installation Notes

Installation is performed by machinists and maintenance mechanics using a standard drill chuck or collet holder that accepts a straight-cylindrical shank. Secure the shank fully and verify runout before beginning a production run. Power down and lock out the machine before changing or inspecting bits. Do not exceed the recommended speeds and feeds for the workpiece material and bit diameter to avoid premature dulling or breakage.
