Hertel 89320923 Screw Machine Drill Bit Wire 42 Hss

Product Description

The HERTEL 89320923 is a screw machine length drill bit designed for high-speed steel drilling in general-purpose metal fabrication, machining, and light manufacturing applications. It is sized to wire gauge 42, which corresponds to 0.0935 inches in decimal. The 118-degree split-point angle provides positive engagement on a wide range of workpiece materials without requiring a center punch. The bright, uncoated finish is appropriate for general-purpose use where coolant or specialty coatings are not required. At 1.75 inches overall length, this short-body geometry reduces deflection and improves rigidity in screw machine and CNC turret applications. Machinists, tool-and-die makers, and production shop technicians are the primary installers.

This bit is built for use in screw machines, turret lathes, drill presses, and CNC machining centers where a compact, rigid drill body is needed. The reduced overall length compared to jobber-length bits makes it well suited for close-tolerance drilling in soft to medium-hardness metals including mild steel, aluminum, brass, and similar materials. The right-hand cutting direction is standard for conventional machine spindle rotation. It is sold individually with a minimum order quantity of 12 units, making it practical for shop restocking or toolcrib replenishment.

Key Features

• Wire size 42 (0.0935 inches decimal) for precision small-diameter hole requirements
• 118-degree point angle for positive engagement on metal and general-purpose substrates
• Screw machine length body reduces deflection in turret and CNC applications
• High-speed steel construction provides durability across general machining operations
• Bright, uncoated finish suitable for standard cutting speeds and dry or flood coolant use
• Right-hand cut compatible with standard machine spindle rotation

Compatibility

Designed as a general-purpose screw machine length drill bit for use in screw machines, turret lathes, drill presses, and CNC machining centers accepting standard straight-shank tooling in the 0.0935-inch diameter range.

Installation Notes

Installation is performed by machinists or toolroom technicians. Verify the drill chuck or collet is rated for the shank diameter before securing the bit. Ensure the machine spindle is fully stopped and the machine is locked out before changing tooling. Do not apply excessive feed pressure on small-diameter bits, as high-speed steel is susceptible to breakage under lateral load or chatter.
