Osg 300-0810 Chucking Reamer Size 46 Solid Carbide

Product Description

The OSG 300-0810 is a solid carbide chucking reamer in wire size 46, designed to produce precise finished bores in metal workpieces. With a reamer diameter of 0.0810 inches and a tight tolerance of +0.0001 to +0.0004 inches, this tool delivers consistent, accurate hole sizing in general machining applications. The straight flute geometry and right-hand cutting direction make it well suited for through-hole and blind-hole finishing operations. At 2 inches overall length with a 0.5 inch flute length, it fits standard drill press and CNC setups using a straight cylindrical shank. Solid carbide construction provides rigidity and wear resistance when working in ferrous and non-ferrous materials.

This reamer is intended for general machining operations where close-tolerance hole finishing is required. The wire size 46 diameter targets small-bore applications common in precision component manufacturing, toolroom work, and production machining environments. Machinists and toolroom technicians working with drill presses, lathes, or CNC machining centers will find this reamer a direct fit for standard chucking setups. No coolant-through capability is present, making it appropriate for use with external coolant or cutting fluid applied at the workpiece.

Key Features

• Solid carbide construction for rigidity and extended tool life in precision boring
• Wire size 46 diameter (0.0810 inches) with tolerance of +0.0001 to +0.0004 inches for close-tolerance finishing
• Straight flute, right-hand cut geometry suitable for through-hole and blind-hole reaming
• Straight cylindrical shank for compatibility with standard chucks and collets
• Bright/uncoated finish for use across a broad range of general machining materials
• 4-flute design balances chip evacuation and surface finish quality

Compatibility

Designed as a general-purpose chucking reamer for standard machining applications requiring wire size 46 bore finishing. Fits any setup accepting a straight cylindrical shank reamer of this diameter class.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the chuck or collet is properly torqued before starting the cut. Apply appropriate cutting fluid externally at the workpiece, as this tool does not have coolant-through capability. Inspect the reamer for chipping or wear before each use, as carbide tooling can fail suddenly if run in a damaged state.
