Titan Usa TR97510 Solid Pilot Counterbore 4 Flute Hss

Product Description

The TITAN USA TR97510 is a solid pilot counterbore designed for precision spot-facing and counterboring operations on ferrous and non-ferrous materials. Built from high speed steel with a bright, uncoated finish, this tool delivers reliable cutting performance in production and maintenance machining environments. It features a 0.787 inch counterbore diameter, a 17/32 inch oversize pilot diameter, and a 1/2 inch shank diameter, making it a stable choice for CNC and manual milling or drill press setups. The 4-flute geometry promotes smooth chip evacuation and reduces chatter during the cut.

This counterbore is intended for creating flat-bottomed recesses that seat cap screw heads flush with or below a workpiece surface. It is compatible with 1/2 inch cap screws and is well suited for use in fabrication shops, machine shops, and industrial maintenance applications. The 7.5 inch overall length provides clearance for deeper setups and longer reach requirements. Machinists and tool and die technicians working on both production runs and one-off jobs will find this tool appropriate for their standard counterboring needs.

Key Features

• 0.787 inch counterbore diameter for precise cap screw seat preparation
• 17/32 inch oversize pilot diameter ensures accurate hole alignment
• 4-flute design for smooth cutting action and efficient chip removal
• High speed steel construction for durability across a range of workpiece materials
• Bright, uncoated finish suitable for general-purpose machining without added coating complexity
• 7.5 inch overall length accommodates deeper workpiece clearance requirements

Compatibility

Designed for use with 1/2 inch cap screws. Features an oversize pilot diameter of 17/32 inch for proper piloting in pre-drilled through-holes.

Installation Notes

Installation of this counterbore is performed by qualified machinists using a milling machine, drill press, or similar machine tool. Secure the 1/2 inch shank firmly in the spindle or chuck before operation and verify that the pilot fits the existing hole without excessive play. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never exceed the machine spindle speed recommended for the workpiece material and tool diameter.
