Titan Usa TR97475 Solid Pilot Counterbore 0.38in 4 Flute Hss

Product Description

The TITAN USA TR97475 is a solid pilot counterbore designed for precision spot-facing and counterboring operations on metal workpieces. Manufactured from high speed steel with a bright, uncoated finish, this tool delivers reliable cutting performance in general machining environments. The 0.38-inch counterbore diameter pairs with a 1/4-inch standard pilot, keeping the bore concentric with the existing hole. Four flutes provide balanced chip evacuation and smooth cutting action. With a 5/16-inch shank diameter and an overall length of 5.625 inches, the TR97475 fits standard drill press and milling machine setups used by machinists and maintenance technicians.

This counterbore is sized for use with 1/4-inch cap screws, making it a practical tool for recessing fastener heads in steel, aluminum, and similar materials during fabrication, assembly, and maintenance work. The standard pilot configuration suits straight through-holes in typical shop and field machining applications. It is sold individually, making it a direct single-unit replacement or addition to a machinist tool kit without requiring a set purchase.

Key Features

• 0.38-inch counterbore diameter for consistent, repeatable spot-face results
• 1/4-inch standard pilot maintains concentricity with pilot hole
• 4-flute geometry for smooth chip removal and cutting balance
• High speed steel construction for durability in metal cutting applications
• Bright, uncoated finish — no coating buildup concerns on close-tolerance work
• Compatible with 1/4-inch cap screws for fastener head recessing

Compatibility

Designed for use with 1/4-inch cap screws. Fits standard drill press and milling setups accepting a 5/16-inch shank diameter.

Installation Notes

Counterbores should be installed and operated by qualified machinists familiar with rotating cutting tools. Secure the shank firmly in a drill chuck or collet rated for the 5/16-inch shank before operation. Always power down and de-energize the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
