Hertel 83246975 Chucking Reamer Letter Y Solid Carbide

Product Description

The HERTEL 83246975 is a solid carbide chucking reamer sized to Letter Y (0.4040 inches diameter) with a bright, uncoated finish. It features a straight flute geometry and a straight cylindrical shank, making it compatible with standard drill chucks and collet holders. The 6-flute configuration provides a smooth, accurate finish on through-holes and blind holes in a wide range of materials. With an overall length of 3.5 inches and a flute length of 1.25 inches, this reamer is suited for precision hole finishing operations on machining centers, lathes, and drill presses. Right-hand cutting direction is standard. Diameter tolerance is held to 0.0000 to 0.0003 inches over nominal, supporting tight-tolerance fit requirements.

This chucking reamer is used in metalworking and machining environments where hole sizing accuracy is critical. Typical applications include finishing drilled or bored holes to Letter Y tolerance in ferrous and non-ferrous metals, plastics, and composites. It is commonly used by machinists and tool-and-die professionals in job shops, production facilities, and maintenance repair operations where consistent, repeatable hole quality is required. The solid carbide construction makes it well suited for harder workpiece materials and higher-speed cutting conditions compared to high-speed steel alternatives.

Key Features

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, ER collet holders, and similar straight-shank toolholding systems on machining centers, lathes, and drill presses requiring a Letter Y hole size.

Installation Notes

This reamer is installed and operated by machinists following standard toolholding and cutting fluid practices. Ensure the shank is fully seated and clamped securely in the chuck or collet before operation. Always confirm spindle speed and feed rate are appropriate for the workpiece material and reamer diameter before cutting. Power down and de-energize the machine before changing or adjusting tooling.
