Titan Usa TR97512 Solid Pilot Counterbore 1.163 in 4 Flute

Product Description

The TITAN USA TR97512 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, it delivers consistent cutting performance in machine shop and field maintenance environments. The tool features a 1.163-inch counterbore diameter, a 25/32-inch oversize pilot diameter, and a 3/4-inch shank for secure chuck or adapter mounting. Four flutes provide efficient chip evacuation and a balanced cut. It is sized for 3/4-inch cap screw compatibility, making it a direct-fit choice for fastener seat preparation in structural and mechanical assemblies. Machinists and maintenance mechanics are the primary users of this tool.

The TR97512 is suited for creating clean, flat-bottomed recesses that seat 3/4-inch cap screw heads flush or below a workpiece surface. Typical applications include drilling and boring operations on machine frames, fixtures, structural steel components, and equipment housings. The oversize pilot diameter helps center the tool in a pre-drilled hole, reducing chatter and improving concentricity of the finished bore. With a 7-3/4-inch overall length, the tool reaches into moderately deep setups without requiring extension tooling.

Key Features

• 1.163-inch counterbore diameter sized for 3/4-inch cap screw head seating
• 25/32-inch oversize pilot for improved centering and reduced runout
• 4-flute geometry for efficient chip clearance and balanced cutting forces
• High speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish — no coating delamination risk in abrasive materials
• 7-3/4-inch overall length provides reach for moderate-depth applications

Compatibility

Designed for use with 3/4-inch cap screws. The 3/4-inch shank is compatible with standard drill press chucks, milling machine collets, and boring bar adapters that accept that shank diameter. Verify pilot hole diameter matches the 25/32-inch oversize pilot before use.

Installation Notes

This tool is installed and operated by machinists or maintenance mechanics using a drill press, milling machine, or similar spindle equipment. Secure the shank firmly in a matched chuck or collet and confirm the workpiece is clamped before starting the spindle. Use cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Inspect the pilot and cutting edges for wear or damage before each use.
