Titan Usa TR94388 Chucking Reamer 0.2505 in Hss Straight

Product Description

The TITAN USA TR94388 is a straight-flute chucking reamer designed for precision hole finishing in machine shop and production environments. Ground from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing of previously drilled or bored holes to a finished diameter of 0.2505 inches. The six-flute, right-hand cutting geometry provides smooth stock removal and a consistent surface finish. With an overall length of 6 inches and a flute length of 1.5 inches, this reamer is suited for use in drill presses, CNC machining centers, and manual lathes. Diameter tolerance is held to plus 0.0002 to minus 0.0000 inches, making it appropriate for tight-fit applications.

This chucking reamer is used in metalworking operations where hole size and finish tolerances are critical. Typical applications include reaming clearance holes for dowel pins, precision bearing bores, and close-tolerance fastener holes in steel, aluminum, cast iron, and similar machinable materials. The straight-cylindrical shank fits standard drill chucks and collet systems. It is intended for use by machinists, tool-and-die makers, and maintenance technicians requiring repeatable, close-tolerance hole finishing.

Compatibility

Designed as a standard chucking reamer for use in drill presses, manual lathes, and CNC machining centers equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank. Part of the TITAN USA TR94 series.

Installation Notes

Secure the shank firmly in a calibrated drill chuck or collet before use and verify runout with a dial indicator where tolerance is critical. Always use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Power down the machine completely before installing or removing the reamer. Follow applicable shop safety standards and manufacturer feed-and-speed recommendations for HSS tooling.
