Hertel 89321632 Screw Machine Drill Bit Wire 13 Hss

Product Description

The HERTEL 89321632 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and plastic. Manufactured from high-speed steel, it carries a wire gauge size of 13, which corresponds to a decimal diameter of 0.185 inches. The 118-degree split-point angle suits standard materials and common shop applications. At 2-3/16 inches overall length, this stub-length bit fits short-stroke drill presses, hand drills, and CNC drilling operations where rigidity and reduced runout matter. The bright, uncoated finish is suitable for use with cutting fluids or dry. Licensed machinists, tool-and-die workers, and maintenance technicians are the typical end users.

This bit is suited for light to medium stock removal in ferrous and non-ferrous materials. The screw machine length format — shorter than a jobber bit — reduces deflection and improves hole accuracy in tightly toleranced applications. Typical install scenarios include production drilling, fixture work, and maintenance drilling in industrial or commercial shop environments where a compact, rigid bit is preferred over a standard jobber-length drill.

Key Features

• Wire gauge size 13, equivalent to 0.185 inches decimal diameter
• High-speed steel construction for durability across general-purpose drilling tasks
• 118-degree point angle compatible with standard drill press and hand-drill use
• Screw machine (stub) length at 2-3/16 inches OAL reduces deflection and improves rigidity
• 1-1/8 inch flute length provides adequate chip clearance for the bit diameter
• Bright uncoated finish compatible with dry cutting or coolant-assisted drilling

Compatibility

Designed as a general-purpose screw machine length drill bit for use in standard drill chucks accepting shank sizes in the 0.150 to 0.200 inch decimal inch range.

Installation Notes

Install in a drill press, hand drill, or CNC spindle using a properly sized chuck; confirm chuck capacity before seating the shank. Secure the workpiece before drilling and use appropriate cutting fluid for ferrous materials to extend tool life. Right-hand cut geometry requires standard forward spindle rotation. Inspect the cutting edges for wear or chipping before each use and replace when point geometry is degraded to avoid oversize holes.
