Titan Usa TR97506 Solid Pilot Counterbore 4 Flutes Hss

Product Description

The TITAN USA TR97506 is a solid pilot counterbore designed for precision counterboring operations in metal fabrication and machining applications. Built from high speed steel (HSS) with a bright, uncoated finish, this tool delivers clean, flat-bottomed recesses for cap screw seating. The counterbore measures 0.412 inches in diameter with a 9/32 inch pilot diameter, classified as an oversize pilot for guided, accurate entry. The 4-flute configuration promotes smooth chip evacuation and a consistent finish. With a 5/16 inch shank diameter and an overall length of 5.625 inches, it fits standard drill press and milling machine chucks used in production and maintenance environments. Machinists, toolmakers, and mechanical contractors are the typical end users.

This counterbore is compatible with 1/4 inch cap screws and is suited for creating properly dimensioned recesses that allow fastener heads to sit flush or below a workpiece surface. It is appropriate for use in light to medium machining on ferrous and non-ferrous metals where HSS tooling meets the application requirements. The oversize pilot provides additional clearance over standard pilot counterbores, making it useful in rework and repair scenarios where hole tolerances may vary slightly from nominal.

Key Features

• 0.412 inch counterbore diameter for 1/4 inch cap screw compatibility
• 9/32 inch oversize pilot diameter for guided entry and alignment
• 4-flute design for efficient chip removal and surface finish quality
• High speed steel construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• 5/16 inch shank diameter fits common drill press and milling chucks

Compatibility

Designed for use with 1/4 inch cap screws. Fits standard 5/16 inch shank toolholders and chucks on drill presses and milling machines.

Installation Notes

This tool is installed and operated by machinists or skilled maintenance technicians on drill presses, milling machines, or similar rotating equipment. Secure the shank firmly in a compatible chuck before use and confirm the workpiece is clamped. Apply appropriate cutting fluid for the material being machined to extend tool life. Do not exceed the tool and machine manufacturer recommended speeds and feeds for HSS counterbores.
