Chicago-latrobe 48535 Screw Machine Drill Bit 35/64 in Hss

Product Description

The CHICAGO-LATROBE 48535 is a screw machine length drill bit designed for high-throughput drilling in metalworking and general fabrication environments. Built from high speed steel with a coated finish, it measures 35/64 inch (0.5469 inches) in diameter and features a 118-degree standard point angle with web thinning for reduced thrust and easier penetration. The spiral flute design and straight-cylindrical shank make it compatible with standard drill chucks and screw machine setups. This bit is sized for production and job-shop environments where shorter length provides added rigidity and improved hole accuracy.

The 48535 is suited for drilling cast iron, non-ferrous metals, and steel in both production and maintenance-repair contexts. Its screw machine length keeps the tool stiff in applications where a standard-length bit would deflect, such as close-tolerance work on lathes, drill presses, and CNC turret machines. The parallel web configuration and regular spiral flute support consistent chip evacuation across these primary workpiece materials.

Key Features

• 35/64 inch (0.5469 inches) diameter with a tight tolerance of +0.0000 to -0.0012 inches
• 118-degree standard point angle with web thinning for reduced entry force
• High speed steel construction with coated finish for extended tool life
• Screw machine (stub) length for maximum rigidity in close-tolerance drilling
• Right-hand cut, 2-flute spiral design for efficient chip removal
• Rated for cast iron, non-ferrous metals, and steel; ISO standard compliant

Compatibility

Designed for use in screw machines, drill presses, lathes, and CNC turret setups where stub-length bits are specified; primary workpiece materials include cast iron, non-ferrous metal, and steel.

Installation Notes

Installation should be performed by a qualified machinist or tool-and-die technician. Secure the shank fully in the drill chuck before operation and verify runout is within acceptable limits. Power down the machine completely before changing bits. Do not exceed the recommended feed and speed ranges for the workpiece material to avoid premature coating wear or tip failure.
