Industrial TR94390 Chucking Reamer

Description:

The Titan TR94390 Chucking Reamer is used in precision machining operations to finish pre-drilled holes to a 0.2520-inch diameter with excellent dimensional accuracy and surface finish. Commonly installed in CNC machining centers, milling machines, drill presses, and manual machine tools where precise hole sizing is required for dowel pins, bushings, bearings, and close-tolerance mechanical assemblies. Machine shops, OEM manufacturers, maintenance departments, and toolmakers use the TR94390 for production machining, fixture manufacturing, repair work, and replacement of worn or damaged chucking reamers.

Applications:

The Titan TR94390 Chucking Reamer is commonly used in precision machining environments including aerospace, automotive, mold and die, industrial equipment manufacturing, fixture production, and general metalworking applications where accurate hole sizing and smooth surface finishes are essential. Its straight-flute design provides stable cutting performance in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials.
