Hertel 83246728 Chucking Reamer 0.1885 in Solid Carbide

Product Description

The HERTEL 83246728 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. Built with a straight flute geometry and a straight cylindrical shank, this reamer delivers consistent, accurate results in hand-feed and machine-feed setups. The 0.1885 inch diameter is classified as an over-size reamer with a tight tolerance of 0.0000 to 0.0002 inches, making it well-suited for applications that require controlled interference or transitional fits. The bright, uncoated carbide construction provides excellent rigidity and wear resistance in a compact 2.75 inch overall length.

This chucking reamer is intended for use in CNC machining centers, drill presses, and manual lathes where repeatable bore sizing is required. The 4-flute, 0.875 inch flute length is appropriate for shallow-to-moderate depth reaming in ferrous and non-ferrous materials. It is commonly used in job shops, tool rooms, and production environments where tight hole tolerances are held to print. The right-hand cutting direction is standard for conventional clockwise spindle rotation.

Key Features

• Solid carbide construction provides high rigidity and extended tool life compared to HSS
• 0.1885 inch over-size diameter with tolerance of 0.0000 to 0.0002 inches for precision fits
• 4-flute straight geometry for smooth, consistent surface finish in reamed bores
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Straight cylindrical shank for direct chuck or collet mounting
• Right-hand cut, compatible with standard clockwise spindle rotation

Compatibility

Designed as a chucking reamer for use in standard drill chucks, ER collets, or equivalent straight-shank toolholders on CNC and manual machine tools. Fits within the 0.1500 to 0.1999 inch reamer diameter range category.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or toolroom technician. Before mounting, ensure the spindle is fully stopped and the machine is in a safe, powered-down state. Secure the straight shank firmly in a matched collet or drill chuck to minimize runout, as excessive runout will degrade hole tolerance and shorten tool life. Use appropriate cutting fluid for the workpiece material and do not exceed the recommended feed rate for the reamer diameter.
