Titan Usa TR97504 Solid Pilot Counterbore 0.302 in 4 Flutes

Product Description

The TITAN USA TR97504 is a solid pilot counterbore designed for precise seat-cutting operations in metalworking and machining applications. Built from high speed steel with a bright, uncoated finish, it delivers consistent cutting performance for boring flat-bottomed recesses ahead of cap screw fasteners. The tool features a 0.302-inch counterbore diameter, a 0.195-inch oversize pilot diameter for accurate hole alignment, and four flutes for efficient chip evacuation. With a 0.25-inch shank diameter and a 5-inch overall length, it mounts securely in standard drill press or milling machine chucks used in precision machining work.

This counterbore is intended for use in machine shops, fabrication environments, and maintenance facilities where cap screw counterboring is a routine operation. It is compatible with No. 8 cap screws and is suited for steel, aluminum, and other machinable metals. The oversize pilot design helps maintain concentricity and reduces chatter during the cutting cycle. Machinists and tool-and-die technicians working on fixture building, repair work, or production runs will find this tool a direct fit for standard counterbore toolholders.

Key Features

• 0.302-inch counterbore diameter for No. 8 cap screw recesses
• 0.195-inch oversize pilot diameter for improved alignment and concentricity
• 4-flute geometry promotes efficient chip removal and smooth finish
• High speed steel construction for durability across a range of machinable metals
• Bright, uncoated finish suitable for general-purpose cutting
• 5-inch overall length with 0.25-inch shank for compatibility with standard chucks

Compatibility

Designed for use with No. 8 cap screws. Fits standard drill press and milling machine toolholders accepting a 0.25-inch shank diameter.

Installation Notes

This tool is installed and operated by machinists using a drill press, milling machine, or similar machine tool. Secure the shank fully in the chuck or toolholder before operation and confirm the pilot engages the pilot hole cleanly before beginning the counterbore cut. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
