Chicago-latrobe 48411 Screw Machine Drill Bit 0.096 in

Product Description

The CHICAGO-LATROBE 48411 is a screw machine length drill bit engineered for heavy-duty drilling in cast iron and steel. It measures 0.096 inches (Wire Size 41) in diameter and features a 135-degree split point that reduces walking and allows drilling to start without a center punch. Constructed from high speed steel with a coated finish, this bit resists heat and wear during high-cycle production work. The web-thinned, parallel web construction reduces thrust requirements and improves chip clearance. Overall length is 1-13/16 inches with a 13/16-inch flute length, making it compact enough for tight-clearance applications on drill presses and screw machines. This is a single-piece package.

The 48411 is suited for production drilling, machine shop work, and maintenance environments where shorter, stiffer bit geometry is required to minimize deflection. The screw machine length format is standard for turret lathes, CNC machining centers, and gang drill setups where extended reach is not needed. Primary workpiece materials are cast iron and steel. The right-hand spiral flute and straight-cylindrical shank fit standard drill chucks without modification. Minimum order quantity is 12 units.

Key Features

• Wire Size 41 (0.096 inches) diameter with a tight tolerance of +0.0000 to -0.0005 inches for precise hole sizing
• 135-degree split point reduces thrust and eliminates the need for a center punch
• Web-thinned, parallel web construction lowers cutting resistance and improves chip evacuation
• High speed steel construction with coated finish for extended tool life in ferrous materials
• Screw machine length body provides added rigidity and reduced deflection versus jobber-length bits
• Meets ISO and NAS 907 (NAS specification designation) standards for dimensional consistency

Compatibility

Designed as an OEM-style replacement or production drill bit for use in standard drill chucks, turret lathes, CNC machining centers, and gang drill setups that accept a straight-cylindrical shank. Rated for cast iron and steel workpiece materials per Series 2159 specifications.

Installation Notes

Machinist or tool-and-die professionals typically install and operate this bit. Secure the straight-cylindrical shank firmly in the drill chuck before operation and verify runout before production runs. Follow applicable shop safety and machine guarding practices when operating drill presses or CNC equipment. Inspect the cutting edge for wear or chipping before each use and replace when diameter tolerance or point geometry can no longer be maintained.
