Osg 300-1160 Chucking Reamer Size 32 Solid Carbide

Product Description

The OSG 300-1160 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. It carries a wire gauge diameter of No. 32, equivalent to 0.1160 inches, and holds a reamer diameter tolerance of +0.0001 to +0.0004 inches, making it suitable for close-tolerance bore work. The reamer features a straight flute geometry, a straight cylindrical shank for secure chuck mounting, and a right-hand cutting direction. With a bright, uncoated finish and four flutes, it is engineered for dimensional accuracy in production and job-shop environments. Machinists and CNC operators working with small-diameter bores will find it appropriate for through-hole finishing in ferrous and non-ferrous materials.

This reamer is intended for general machining applications where hole size consistency is critical. It fits standard chucking setups on manual lathes, CNC turning centers, and drill presses. The 2.25-inch overall length and 0.625-inch flute length make it well-suited for shallow to moderate-depth bore finishing in small workpieces or component features requiring tight dimensional control. It is sold individually and carries no coolant-through capability, making it most applicable in dry or flood-coolant-from-external-source setups.

Key Features

• Wire Size No. 32 diameter — 0.1160 inches decimal equivalent
• Solid carbide construction for wear resistance and dimensional stability
• Straight flute, straight shank design for straightforward chuck mounting
• Four-flute geometry for consistent surface finish in small bores
• Diameter tolerance of +0.0001 to +0.0004 inches for close-fit work
• Bright, uncoated finish — Series 300D standard carbide reamer

Compatibility

Designed as an OEM-style chucking reamer for general machining applications requiring a No. 32 wire gauge diameter bore finish in standard straight-shank chuck holders.

Installation Notes

Chucking reamers are installed and removed by qualified machinists using standard three-jaw or collet-style chuck holders. Ensure the machine spindle is fully stopped and power is isolated before mounting or removing the reamer. Proper alignment between the reamer centerline and the pre-drilled pilot hole is critical to achieving tolerance; undersized pilot holes should be used per standard reaming practice. Do not use this reamer for stock removal beyond its intended finishing allowance.
