Osg 300-0906 Chucking Reamer 2.3mm Straight Flute Carbide

Product Description

The OSG 300-0906 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. With a reamer diameter of 2.3 mm (0.0906 inches) and a diameter tolerance of +0.0001 to +0.0004 inches, this tool delivers tight, accurate bores suitable for close-tolerance work. The straight flute geometry and right-hand cutting direction make it well suited for most standard drilling setups. Machinists and tool-room technicians install this reamer in a chuck or collet to bring an existing drilled hole to its final dimension with consistent surface finish and precise sizing.

This reamer is intended for use in general machining environments where small-diameter hole finishing is required. At 2.3 mm, it falls in the 2.00 to 3.00 mm diameter range and is commonly used in precision component manufacturing, tooling fixtures, and similar applications. The straight cylindrical shank allows straightforward chuck mounting on CNC machining centers, drill presses, and manual mills. The 12 mm flute length accommodates typical shallow-to-moderate depth finishing passes at this diameter.

Key Features

• Solid carbide construction provides rigidity and wear resistance for accurate, repeatable finishes
• Diameter tolerance of +0.0001 to +0.0004 inches delivers close-tolerance hole sizing
• 4-flute straight design supports right-hand cutting in standard machine setups
• Bright/uncoated finish — ready to use as supplied, no coating buildup to affect diameter
• Straight cylindrical shank for easy chuck or collet mounting
• Part of OSG Series 300D, intended for general machining applications

Compatibility

Designed as an OEM-style chucking reamer for general machining applications requiring 2.3 mm finished hole diameter; fits standard chucks and collets accepting a straight cylindrical shank at this diameter range.

Installation Notes

A qualified machinist should install this reamer in a properly sized chuck or collet, ensuring the shank is fully and concentrically seated before operation. Power down the machine spindle completely before mounting or removing the reamer. Confirm correct starting hole size and allowance before reaming, as carbide tooling at this diameter is sensitive to side loading and runout. Follow applicable shop safety procedures and machine manufacturer guidelines for small-diameter carbide tools.
