Titan Usa TR94184 Chucking Reamer 0.1280 in Hss 4 Flute

Product Description

The TITAN USA TR94184 is a straight-flute chucking reamer designed to bring bored or drilled holes to a precise finished diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers a reamer diameter of 0.1280 inches with a tolerance of +0.0002 to -0.0000 inches, making it suitable for tight-tolerance through-hole finishing operations. The 4-flute, right-hand cutting geometry and straight-cylindrical shank allow it to be held in standard drill chucks or collets. With an overall length of 3.5 inches and a flute length of 0.875 inches, this reamer is installed and operated by machinists, tool and die makers, and maintenance technicians working on precision hole-finishing tasks.

The TR94184 is suited for light-material removal in finishing passes on holes that have been pre-drilled or bored to near-net size. Its straight flute design is appropriate for through-hole reaming in materials where chip evacuation from the back of the hole is not a concern. Typical applications include machine shops, maintenance and repair operations, and production environments requiring consistent hole sizing in ferrous and non-ferrous workpiece materials. This reamer is sold individually and is part of the TITAN USA TR94 series.

Installation Notes

This reamer is operated by qualified machinists or technicians familiar with precision hole-finishing procedures. Ensure the workpiece is securely fixtured and the shank is fully seated and clamped in the chuck or collet before operation. Pre-drill or bore the hole to the appropriate undersize before reaming to achieve the specified tolerance. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
