Hertel 79889218 Chucking Reamer 0.095 in Solid Carbide

Product Description

The HERTEL 79889218 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.095 inches and a diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers tight, repeatable bore dimensions in a single pass. The straight flute geometry and right-hand cut make it well suited for finishing operations in through-holes and blind holes where chip evacuation is straightforward. The bright, uncoated carbide construction provides rigidity and wear resistance when working with a range of workpiece materials. Machinists and toolroom professionals install this reamer in CNC machining centers, drill presses, and manual mills.

This reamer is used in precision machining applications where close-tolerance hole finishing is required. The 0.095-inch diameter falls within the small-bore range, making it applicable for instrument components, hydraulic fittings, medical device parts, and other small-diameter bore work. The straight cylindrical shank seats directly in a chuck or collet holder without additional adapters. The 4-flute configuration balances surface finish quality with chip clearance in short-flute finishing cuts. It is sold and packaged as a single unit.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision finishing operations
• Tight diameter tolerance of 0.0000 to 0.0002 inches for repeatable bore accuracy
• 4-flute straight geometry promotes consistent surface finish in through-holes and blind holes
• Bright, uncoated finish suits a wide range of workpiece materials without coating interference
• Straight cylindrical shank mounts directly in standard chucks or collet holders
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in CNC machining centers, drill presses, and milling machines equipped with a standard chuck or collet system accepting a straight cylindrical shank in the 0.095-inch diameter range.

Installation Notes

Installation and operation of this reamer should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from the chuck or collet holder. Confirm the shank is fully seated and the holding device is torqued to the machine or toolholder manufacturer's specification before running. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life and surface finish quality.
