Hertel 79889762 Chucking Reamer 0.2 in Solid Carbide

Product Description

The HERTEL 79889762 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.2 inches and a diameter tolerance of 0.0000 to 0.0002 inches, it delivers tight, consistent bore sizing on through-holes and blind holes alike. The bright, uncoated solid carbide construction provides rigidity and wear resistance suited to ferrous and non-ferrous materials. A straight-cylindrical shank seats securely in standard collets or drill chucks. Machinists and tool-and-die professionals use this reamer where hole geometry and surface finish must meet close tolerances.

This chucking reamer is suited for bench drill press, CNC machining center, or manual lathe operations where a 0.2-inch finished bore diameter is required. The 1-inch flute length accommodates shallow-to-moderate depth holes, and the 3-inch overall length provides clearance in most standard tool holders. The straight flute geometry is appropriate for short-chipping materials and stable cutting conditions where chip evacuation is not a primary concern.

Key Features

• Solid carbide construction for rigidity and extended tool life
• Diameter tolerance of 0.0000 to 0.0002 inches for precise bore sizing
• Straight flute design suited to short-chipping materials
• Right-hand cutting direction for standard spindle rotation
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank for compatibility with standard collets and drill chucks

Compatibility

Designed as an OEM-style chucking reamer for use in standard collet chucks, drill chucks, or floating reamer holders accepting a straight-cylindrical shank at 0.2-inch diameter.

Installation Notes

Installation and operation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before seating or removing the reamer from the holder. Use appropriate cutting fluid for the workpiece material to maintain tool life and surface finish. Do not exceed the recommended feed and speed parameters for solid carbide tooling in the applicable material.
