Titan Usa TR94508 Chucking Reamer 0.318 in Hss 6 Flute

Product Description

The TITAN USA TR94508 is a straight-shank chucking reamer designed to bring bored or drilled holes to a precise finished diameter of 0.3180 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The six-flute straight configuration provides smooth cutting action and good chip clearance in through-hole and blind-hole applications. With an overall length of 6 inches and a flute length of 1.5 inches, the TR94508 fits standard drill press and milling machine chucks for reliable, repeatable sizing in machine shop and maintenance environments.

This reamer is suited for machine reaming operations where close-tolerance hole finishing is required. Typical applications include production and job-shop work on steel, aluminum, brass, and cast iron. It is used in drill presses, lathes, and milling machines by machinists and maintenance technicians. The straight cylindrical shank seats directly in collets or drill chucks without special toolholding. Series TR94 covers a range of standard decimal inch diameters, making individual replacements straightforward when a single size wears out.

Key Features

Compatibility

Designed as a machine chucking reamer for use in drill presses, lathes, and milling machines requiring a 0.3180 inch finished hole diameter. Part of the TITAN USA TR94 series of straight-shank HSS chucking reamers.

Installation Notes

Machine chucking reamers are installed and operated by machinists; the workpiece and machine spindle should be fully stopped before mounting or removing the tool. Secure the straight shank firmly in the chuck or collet to prevent runout, which directly affects finished hole quality. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Follow standard shop safety practices and machine manufacturer guidelines when operating rotating tooling.
