Osg 300-1535 Chucking Reamer 0.1535 in Solid Carbide

Product Description

The OSG 300-1535 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 0.1535 inches (3.90 mm), a straight flute geometry, and right-hand cutting direction, this tool delivers consistent, tight-tolerance bores in a single pass. The straight shank allows direct mounting in standard drill chucks, collets, or toolholders. At 64 mm overall length with a 19 mm flute length, the compact profile suits benchtop mills, CNC machining centers, and manual drill presses handling small-bore work. Installation and use require no special adapters beyond a compatible straight-shank holder.

This reamer is suited for production and repair work where hole diameter consistency is critical. The solid carbide construction provides rigidity and wear resistance when reaming ferrous metals, aluminum, brass, and similar materials. Typical applications include precision instrument components, hydraulic bodies, pneumatic valve bores, and fixture work where reamed holes must meet close dimensional tolerances. The right-hand cut makes it compatible with conventional spindle rotation on standard machine tools.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard and abrasive materials
• Reamer diameter of 0.1535 inches (3.90 mm) for close-tolerance hole finishing
• Straight flute design for smooth chip evacuation in through-hole and short blind-hole applications
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight shank for direct chuck or collet mounting without adapters
• Compact 64 mm overall length with 19 mm flute length suited to benchtop and CNC setups

Compatibility

Designed as an OEM-style chucking reamer for use in any standard straight-shank toolholder, drill chuck, or collet system accommodating the specified shank diameter.

Installation Notes

Chucking reamers are installed and serviced by machinists and toolroom technicians. Always power down and lock out the machine spindle before changing tooling. Secure the shank fully within the chuck or collet to the recommended engagement depth for the holder in use. Use appropriate cutting fluid for the workpiece material to maximize tool life and bore finish quality.
