Hertel 89321624 Screw Machine Drill Bit Wire 41 Hss

Product Description

The HERTEL 89321624 is a screw machine length drill bit designed for general-purpose drilling in metal, plastic, and similar materials. Built from high-speed steel with a bright, uncoated finish, this bit features a 118-degree split-free point angle for clean entry and reliable centering on flat and curved surfaces. The screw machine length format means a shorter overall length than a standard jobber bit, which increases rigidity and reduces deflection in tight setups, machine tool turrets, and drill press fixtures. At 0.0960 inch in diameter, it corresponds to wire gauge size 41. Licensed tradespeople and machining professionals use this bit for precision small-hole work where dimensional accuracy matters.

This bit is suited for use in CNC machines, turret lathes, drill presses, and handheld drill motors where a compact, rigid bit is preferred. The right-hand cut geometry works with standard right-hand rotating spindles found across virtually all common machine tools. The 13/16-inch flute length provides adequate chip clearance for the depth of cut typical in screw machine applications. It is sold individually and is appropriate for production environments and maintenance shops that need precise small-diameter holes in ferrous and non-ferrous workpieces.

Key Features

• Wire gauge size 41, equivalent to 0.0960 inch diameter
• 118-degree point angle for general-purpose drilling and reliable self-centering
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• Screw machine length body increases rigidity and reduces deflection compared to jobber-length bits
• Right-hand cut matches standard spindle rotation on all common machine tools

Compatibility

Designed as an OEM-style general-purpose screw machine drill bit for use in standard drill chucks and collet holders accepting bits with a 0.0960 inch shank diameter.

Installation Notes

Installation is performed by machinists, toolroom technicians, or maintenance professionals. Secure the bit firmly in the chuck or collet before operation and confirm runout is within acceptable tolerance for the application. Power down and de-energize the machine spindle completely before changing or inspecting bits. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish.
