Hertel 83246942 Chucking Reamer Letter T Solid Carbide

Product Description

The HERTEL 83246942 is a solid carbide chucking reamer in Letter T size, designed for precision hole finishing in machining applications. With a reamer diameter of 0.3580 inches and a tight tolerance of 0.0000 to 0.0003 inches, this tool delivers accurate, repeatable bore sizing in a single pass. The straight flute geometry and right-hand cutting direction make it well suited for through-hole and short blind-hole reaming in a variety of workpiece materials. At 3.5 inches overall length with a 1.25-inch flute length, it fits standard chuck setups on mills, drill presses, and CNC machining centers. The bright, uncoated finish keeps the carbide substrate exposed for use where coating interaction with the workpiece is a concern.

This reamer is intended for use in metalworking and machining environments where hole tolerances demand more precision than a drill alone can provide. It is commonly used in job shops, toolrooms, and production machining cells to finish pre-drilled or bored holes to a Letter T diameter. The straight cylindrical shank allows direct clamping in a drill chuck, collet, or floating reamer holder. Six flutes distribute cutting load evenly, reducing chatter and improving surface finish in ferrous and non-ferrous materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Letter T diameter (0.3580 inches) with tolerance of 0.0000 to 0.0003 inches for precision hole sizing
• Six straight flutes for even cutting load and improved bore finish
• Right-hand cutting direction, compatible with standard spindle rotation
• Straight cylindrical shank for use in drill chucks, collets, or floating holders
• Bright, uncoated finish — no coating interaction with workpiece material

Compatibility

Designed as a standard chucking reamer for use in any machine spindle accepting a straight cylindrical shank; suitable for mills, drill presses, and CNC machining centers where a Letter T (0.3580 inch) finished bore diameter is required.

Installation Notes

Chucking reamers are installed and removed by qualified machinists following standard lockout procedures for the machine tool in use. Ensure the spindle is fully stopped and the machine is de-energized before inserting or removing the tool from the chuck or collet. Use a floating reamer holder when possible to allow self-alignment and prevent tool deflection. Always ream a pre-drilled or bored hole that is undersized by the appropriate stock allowance for the material being cut — do not attempt to ream from a raw casting or an over-sized hole.
