Hertel 89320618 Screw Machine Drill Bit 32 Hss 118

Product Description

The HERTEL 89320618 is a screw machine length drill bit designed for general-purpose metal drilling in production and maintenance applications. Built from high-speed steel with a bright, uncoated finish, it features a 118-degree split point angle suited for drilling into mild steel, aluminum, brass, and similar materials. The shorter-than-jobber-length body reduces deflection and improves hole accuracy in tight setups. At a wire gauge size of 32, it produces a 0.116-inch diameter hole. Overall length is 1.875 inches with a 0.875-inch flute length. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the typical users of this size class.

Screw machine length drill bits are standard in CNC lathes, drill presses, automatic screw machines, and turret setups where rigidity and short overhang matter. The 32 wire gauge size is commonly specified for close-tolerance hole work, tapping pre-drill operations, and light production runs across metalworking, fabrication, and mechanical maintenance environments. The right-hand cutting direction is compatible with standard spindle rotation on all conventional machine tools.

Key Features

• Wire gauge size 32, equivalent to 0.116-inch diameter
• 118-degree conventional point angle for general-purpose drilling
• High-speed steel construction for durability across a range of workpiece materials
• Bright, uncoated finish — no coating to chip or peel
• Screw machine length body reduces deflection in short-overhang setups
• Right-hand cut, compatible with standard machine spindle rotation

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for use in drill presses, CNC lathes, turret lathes, and automatic screw machines accepting standard straight-shank tooling at the 0.116-inch diameter range.

Installation Notes

Install this bit into a compatible chuck or collet and verify runout before cutting. Secure the workpiece firmly before drilling to prevent walking at point contact. Use appropriate cutting fluid for ferrous materials to extend tool life. Always wear eye protection and follow applicable machine shop safety practices when operating drilling equipment.
