Osg 300-1935 Chucking Reamer Size 10 Solid Carbide

Product Description

The OSG 300-1935 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. Carrying a wire gauge size of 10 and a decimal diameter of 0.1935 inches, this reamer holds a tight tolerance of +0.0001 to +0.0004 inches, making it suitable for work where bore accuracy is critical. The straight flute geometry and right-hand cutting direction make it appropriate for through-holes and conventional drilling setups. With an overall length of 2.75 inches and a flute length of 0.875 inches, this is a compact tool built for light-duty finishing passes on the bench or in a CNC machining center.

The OSG 300-1935 is used in general machining environments where a close-tolerance reamed hole is required in ferrous or non-ferrous workpieces. The straight-cylindrical shank allows direct mounting in standard chucks and collet holders without special tooling. This reamer is typically deployed in job shops, maintenance facilities, and production machining cells where wire-gauge-sized holes need clean, accurate finishes. Four flutes provide a balance of stock removal and surface quality for typical reaming allowances.

Key Features

• Solid carbide construction for rigidity and wear resistance in general machining
• Diameter of 0.1935 inches (Size 10 wire gauge) with tolerance of +0.0001 to +0.0004 inches
• Straight flute, right-hand cut geometry suitable for through-hole reaming
• 4-flute design balances material removal rate with hole surface finish
• Bright/uncoated finish for use across a broad range of workpiece materials
• Straight-cylindrical shank for direct mounting in chucks and collet holders

Compatibility

Designed as an OEM-style chucking reamer for general machining applications requiring a Size 10 wire gauge diameter finish bore.

Installation Notes

Chucking reamers are installed and operated by machinists in lathes, drill presses, or CNC machining centers. Power down and lock out the machine spindle before changing tooling. Secure the straight shank firmly in a collet or chuck to minimize runout, which directly affects hole tolerance. Always pre-drill or bore the hole close to final size before reaming, and apply appropriate cutting fluid for the workpiece material.
