Titan Usa TC87453 Chucking Reamer 3/8 in Solid Carbide

Product Description

The TITAN USA TC87453 is a solid carbide chucking reamer designed to produce precise, finished-diameter holes in metal workpieces. Running a 3/8 inch (0.3750 inch decimal) cutting diameter with a tolerance of +0.0003 to -0.0000 inches, it holds tight bore tolerances that hand reamers and drill bits cannot achieve. The 6-flute, right-hand cutting geometry with a straight flute design promotes clean chip evacuation and a smooth bore finish. Overall length is 3.5 inches with a 1.25 inch flute length and a straight-cylindrical shank for secure chuck engagement. Machinists and tool-and-die technicians use this reamer on manual lathes, drill presses, and CNC machining centers.

The TC87453 is suited for finishing pre-drilled or bored holes to 3/8 inch nominal diameter in steel, cast iron, aluminum, and similar machinable materials. The bright, uncoated carbide surface is well matched to applications where coating buildup would affect dimensional accuracy or where the operator is running a dry or light-fluid cutting environment. It is part of the TITAN USA TC87 series, a line of solid carbide chucking reamers built to consistent dimensional standards for production and job-shop use.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding bore-finishing operations
• 3/8 inch (0.3750 inch) cutting diameter with +0.0003 to -0.0000 inch tolerance for tight bore fits
• 6-flute, right-hand straight flute geometry for clean chip removal and consistent surface finish
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Bright, uncoated finish suitable for a wide range of machinable metals
• 3.5 inch overall length with 1.25 inch flute length for controlled depth reach

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers accepting a straight-cylindrical shank tool in 3/8 inch nominal bore applications.

Installation Notes

A licensed machinist or experienced toolroom technician should secure the reamer firmly in a drill chuck or collet before use, verifying runout is within acceptable limits to prevent bell-mouthing the bore. Power down and de-energize the machine spindle completely before tool changes. Always pre-drill or bore the hole to the correct undersize before reaming to allow proper material removal and avoid tool deflection. Do not use this reamer to remove excess stock; it is a finishing tool intended for light material removal only.
