Titan Usa TR94182 Chucking Reamer 0.1270 in 4 Flute Hss

Product Description

The TITAN USA TR94182 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing in through-hole and blind-hole reaming operations. The reamer measures 0.1270 inches in diameter with a tolerance of +0.0002 to -0.0000 inches, ensuring tight dimensional control. Overall length is 3.5 inches, with a 0.875-inch flute length and a straight-cylindrical shank for secure chuck mounting. With 4 right-hand cutting flutes, this tool is suited for use in drill presses, lathes, and CNC machining centers.

This chucking reamer is used in machine shop environments for finish-reaming small-diameter holes to precise tolerances. Its straight-cylindrical shank seats directly in drill chucks or collets without the need for taper adapters. The 0.1270-inch diameter places it in the 0.1000 to 0.1499-inch range, making it appropriate for close-tolerance work in ferrous and non-ferrous materials. Installation is performed by machinists and tool-and-die professionals in both production and job-shop settings.

• High-speed steel (HSS) construction for durability in general-purpose machining
• Straight-cylindrical shank for direct chuck or collet mounting
• 4 straight, right-hand cutting flutes for smooth material removal
• Bright, uncoated finish suitable for use with standard cutting fluids
• Part of the TR94 series, a consistent family of small-diameter chucking reamers

Compatibility

Designed as an OEM-style replacement and standard cutting tool for machine shop use; compatible with any drill press, lathe, or machining center capable of holding a straight-cylindrical shank and operating within the feed and speed parameters appropriate for HSS tooling.

Installation Notes

This reamer is installed and operated by machinists using standard drill chucks or collets. Ensure the workpiece is securely fixtured and the spindle is at the correct RPM for the material and diameter before engaging the cut. Apply appropriate cutting fluid to extend tool life and improve surface finish. Never use a chucking reamer to remove excessive stock; pre-drill or bore the hole to near-final size before reaming.
