Titan Usa TR94181 Chucking Reamer 0.1265 in Hss 4 Flute

Product Description

The TITAN USA TR94181 is a straight-flute chucking reamer designed for precision hole finishing in machine shop and production environments. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it features a 0.1265-inch reamer diameter held to a tight tolerance of +0.0002 to -0.0000 inches. The 4-flute, right-hand cutting design provides smooth material removal and accurate sizing in a range of workpiece materials. At 3.5 inches overall length with a 0.875-inch flute length and a straight-cylindrical shank, this reamer is suited for use in drill presses, CNC machining centers, and manual lathes.

This reamer is intended for chucking applications where a driven, machine-held tool is required for finish reaming to close dimensional tolerances. It is part of the TR94 series, which covers reamer diameter ranges from 0.1000 to 0.1499 inches. Typical use cases include production reaming of precision bores in ferrous and non-ferrous metals where hole size, roundness, and surface finish are critical. The straight-cylindrical shank seats directly in a standard drill chuck or collet without additional adapters.

Key Features

• Part of the TR94 series covering the 0.1000 to 0.1499-inch diameter range

Compatibility

Designed as an OEM-style replacement or standard tooling selection for machine-driven chucking reamer applications requiring a 0.1265-inch finished bore diameter with a straight-cylindrical shank.

Installation Notes

Installation is performed by a machinist or tooling technician in a machine shop environment. Power down and lock out the machine before loading or removing the reamer from the chuck or collet. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or precision collet to prevent runout. Inspect the reamer for chips or edge damage before each use, and apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
