Osg 300-1660 Chucking Reamer Wire 19 0.1660 in Solid Carbide

Product Description

The OSG 300-1660 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. It produces accurate, close-tolerance bores at a wire size 19 diameter of 0.1660 inches, with a reamer diameter tolerance of +0.0001 to +0.0004 inches. The tool features a bright, uncoated finish and a straight cylindrical shank for secure seating in drill chucks, collets, or toolholders. With an overall length of 2.75 inches and a flute length of 0.875 inches, this reamer is suited for shallow-hole finishing passes in ferrous and non-ferrous materials. It is part of OSG series 300D and cuts right-hand with four straight flutes.

This chucking reamer fits general metalworking and production machining environments where tight hole-diameter tolerances are required. It is used in CNC machining centers, drill presses, and manual lathes for final-pass reaming of drilled or bored holes. Applications include fixture work, tooling components, and precision part finishing where hole geometry and surface finish matter. The straight flute geometry suits through-hole and blind-hole reaming in materials that do not require spiral chip evacuation. No coolant-through capability means external flood or mist coolant should be applied during use.

Key Features

• Wire size 19 diameter at 0.1660 inches with tolerance of +0.0001 to +0.0004 inches for precise fits
• Solid carbide construction for wear resistance and dimensional stability in hard or abrasive materials
• Four straight flutes for stable cutting action in through-hole and blind-hole applications
• Straight cylindrical shank compatible with standard drill chucks and collets
• Bright uncoated finish suitable for general machining without specialized coating requirements
• Right-hand cutting direction, standard for conventional reaming setups

Compatibility

Designed as an OEM-style solid carbide chucking reamer for general machining applications, compatible with standard drill chucks, ER collets, and toolholders accepting a straight cylindrical shank at the 0.1660-inch diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Apply appropriate external coolant or cutting fluid during reaming to maintain tool life and hole quality. Do not exceed the recommended feed and speed parameters for solid carbide reamers in the target workpiece material.
