Titan Usa TC87312 Chucking Reamer 0.2505 in Solid Carbide

Product Description

The TITAN USA TC87312 is a solid carbide chucking reamer designed for precision hole finishing in machining applications. With a reamer diameter of 0.2505 inches and a tight tolerance of +0.0003 to -0.0000 inches, this tool delivers accurate, repeatable bore sizing in a single pass. The 4-flute, straight-flute geometry with right-hand cutting direction provides clean material removal and smooth finishes. At 3 inches overall length with a 1-inch flute length and a straight-cylindrical shank, the TC87312 seats securely in standard chuck-style holders. Machinists and tool-and-die professionals use this reamer for production and maintenance work where bore precision is critical.

This reamer is suited for finishing pre-drilled or bored holes in metal components where close dimensional tolerances are required. The bright, uncoated finish makes it appropriate for a range of ferrous and non-ferrous materials. The straight-cylindrical shank provides straightforward setup in drill presses, CNC machining centers, and manual lathes equipped with a collet or drill chuck. No coolant-through capability means this tool is intended for flooded or brush-applied external coolant setups. It is sold individually and is part of the TC87 Series from TITAN USA.

Key Features

• Solid carbide construction for rigidity and wear resistance
• 0.2505 inch reamer diameter with +0.0003 to -0.0000 inch tolerance for precision bore finishing
• 4-flute, straight-flute geometry with right-hand cutting direction
• Bright, uncoated finish suitable for general machining applications
• Straight-cylindrical shank for compatibility with standard chuck-style toolholders
• Compact 3 inch overall length with 1 inch flute length for short-reach setups

Compatibility

Designed for use in standard chuck-style toolholders accepting a straight-cylindrical shank; suited for drill presses, CNC machining centers, and manual lathes where external coolant delivery is available.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations. Ensure the workpiece and toolholder are securely clamped before operation and that the spindle is fully stopped before tool changes. Apply external coolant or cutting fluid at the cutting zone to manage heat and extend tool life. Do not use this tool as a drill; always ream a pre-drilled or bored hole sized appropriately for the reaming allowance.
