Osg 300-0630 Chucking Reamer 1.6mm Solid Carbide

Product Description

The OSG 300-0630 is a solid carbide chucking reamer designed for precision hole finishing in general machining applications. With a 1.6 mm (0.0630 inch) diameter and a four-flute straight configuration, this reamer delivers tight dimensional control, holding a diameter tolerance of +0.0001 to +0.0004 inches. The bright, uncoated solid carbide construction provides the rigidity and edge retention needed for accurate sizing in a wide range of workpiece materials. Overall length is 38 mm with a 10 mm flute length, making it well suited for shallow to moderate-depth finishing passes. Machinists and tool-and-die professionals specify this reamer where hole geometry and surface finish are critical.

The OSG 300-0630 is intended for general machining environments where precise bore finishing is required. Its straight cylindrical shank seats securely in collet chucks, drill chucks, and floating reamer holders on CNC machining centers, turret lathes, and drill presses. The straight-flute geometry is effective in through-holes and blind holes with adequate chip clearance. This reamer is part of the OSG 300D series, which covers the 1.00 mm to 2.00 mm diameter range for small-bore applications in precision component manufacturing, mold work, and fixture production.

Key Features

• Solid carbide construction for superior rigidity and edge retention in precision reaming
• 1.6 mm (0.0630 inch) diameter with tolerance of +0.0001 to +0.0004 inches for tight bore control
• Four straight flutes with right-hand cutting direction
• Bright uncoated finish suitable for a broad range of workpiece materials
• Straight cylindrical shank for compatibility with standard collet and drill chuck toolholding
• No coolant-through requirement simplifies toolholding setup

Compatibility

Designed as an OEM-style replacement and standard chucking reamer for general machining applications requiring a 1.6 mm diameter straight-flute solid carbide tool in the OSG 300D series.

Installation Notes

Installation and use should be performed by qualified machinists familiar with rotary cutting tool practices. Ensure the machine spindle and toolholder are fully powered down and locked out before mounting or removing the reamer. Seat the straight shank fully and evenly in the collet or chuck before tightening to manufacturer-specified clamping procedures for the toolholder in use. Inspect the cutting edges for chipping or wear before each use, as carbide reamers are brittle and sensitive to side loads or interrupted cuts.
