Hertel 89320857 11/32 in Hss Screw Machine Drill Bit

Product Description

The HERTEL 89320857 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high-speed steel with a bright, uncoated finish, this bit measures 11/32 inches (0.3438 inches decimal) in diameter with a 3-inch overall length and a 1-11/16-inch flute length. The shortened screw machine length profile provides added rigidity over jobber-length bits, reducing deflection in drill press and turret lathe applications. The 118-degree split-point angle is the standard geometry for general-purpose work across a wide range of materials. Machinists, tool room technicians, and maintenance professionals use this bit for production and repair drilling tasks.

This bit is suited for use in drill presses, CNC turret lathes, screw machines, and hand-held power drills where a stubby, rigid bit is preferred. The right-hand cutting direction is standard for conventional drilling operations. Its general-purpose grade makes it appropriate for light-to-moderate production environments, maintenance shops, and trade applications where a reliable, uncoated HSS bit is specified. The compact overall length makes it a common choice when clearance is limited or when maximum bit stiffness is required for accurate hole location.

Key Features

• 11/32-inch (0.3438 inches) diameter for precise sizing within the 0.3000 to 0.3500 inches drill bit size range
• Screw machine length body provides greater rigidity and reduced deflection versus jobber-length bits
• High-speed steel construction handles general-purpose drilling across metal, wood, and plastic
• 118-degree point angle is standard geometry for versatile, everyday drilling applications
• Bright, uncoated finish allows easy visual inspection for wear and re-sharpening
• Right-hand cut, compatible with standard drill chucks and screw machine spindles

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill press chucks, turret lathe spindles, and hand-held power drill chucks accepting 11/32-inch shanks.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before starting the spindle. Power down and de-energize the machine completely before changing or inspecting bits. Use appropriate cutting fluid for metal drilling to extend tool life and maintain hole quality.
