Hertel 89321210 Drill Bit 27/32 Inch 118 Degree Hss

Product Description

The HERTEL 89321210 is a screw machine length drill bit designed for high-volume drilling applications where a shorter, more rigid tool body improves accuracy and reduces deflection. Ground from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 118-degree split-point angle that centers on contact and works well across a wide range of metals, plastics, and general-purpose materials. The 27/32-inch (0.8438 inch decimal) diameter and 5-3/8-inch overall length make it a compact alternative to jobber-length bits, favoring use in drill presses, screw machines, and CNC turret setups where stub rigidity is preferred.

Screw machine length drill bits are standard tooling in production machining environments, metal fabrication shops, and maintenance operations. This bit is suited for drilling through mild steel, aluminum, brass, and similar materials at moderate cutting speeds. Right-hand cutting direction is compatible with standard drill press chucks and CNC spindles. General-purpose grade construction makes it appropriate for everyday throughhole drilling without specialized coatings or geometries.

Key Features

• 27/32 inch diameter (0.8438 inch decimal) for precise hole sizing
• 118-degree point angle for general-purpose metal and plastic drilling
• High-speed steel construction provides durability across a broad material range
• Screw machine length body improves rigidity and reduces deflection versus jobber-length bits
• Bright, uncoated finish allows easy visual inspection of tool wear
• Right-hand cut compatible with standard drill presses, turret lathes, and CNC machines

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill press chucks, CNC turret heads, and screw machine spindles accepting 27/32-inch shank tooling.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool operators familiar with cutting tool safety. Secure the bit firmly in the chuck and verify concentricity before beginning a cut. Always power down and de-energize the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
