Scientific Cutting Tools PRSS-02 Taper Pipe Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS PRSS-02 is a carbide-tipped taper pipe reamer designed for cutting and sizing tapered pipe threads in metal workpieces. It features a 0.45-inch large end diameter, a 0.409-inch small end diameter, and a 1.405-inch flute length. The straight flute geometry and right-hand cut make it well-suited for controlled, precise reaming operations on pipe ports and threaded fittings. Licensed plumbers, pipefitters, and machinists use this tool when preparing ports for leak-free tapered pipe thread connections, particularly in hydraulic, pneumatic, and fluid-system applications. The bright finish helps resist built-up edge during cutting.

This reamer is built for 1/4-18 NPT pipe port applications, making it a standard choice when opening or finishing tapered pipe ports in manifold blocks, valve bodies, and fittings. With an overall length of 2.91 inches and a 0.5-inch straight shank, it mounts directly into standard drill chucks, collet holders, or milling machine spindles. The 0.75-inch body diameter provides rigidity during the cut. The three-flute design balances cutting speed with surface finish quality on both ferrous and non-ferrous materials.

Key Features

• Carbide-tipped construction for extended tool life on hard and abrasive materials
• Three straight flutes with right-hand cut for controlled stock removal
• 1/4-18 NPT taper pipe port geometry ensures proper thread-seat sizing
• 0.5-inch straight shank fits standard chucks and collet holders
• Bright finish reduces friction and helps maintain sharp cutting edges
• Compact 2.91-inch overall length suits tight-access port locations

Compatibility

Designed for use on 1/4-18 NPT tapered pipe port applications across a range of metal workpieces including valve bodies, manifolds, and hydraulic or pneumatic fittings. Compatible with standard 0.5-inch straight-shank toolholders, drill chucks, and collet systems.

Installation Notes

This tool is typically operated by machinists, pipefitters, or plumbers using a drill press, lathe, or CNC machining center. Always secure the workpiece before beginning the reaming operation and use cutting fluid appropriate for the base material to extend tool life and improve surface finish. Do not exceed the recommended reamer diameter range of 0.4000 to 0.4999 inches for this tool. Follow applicable shop safety practices and applicable codes when preparing pipe port connections for pressure-bearing systems.
