Scientific Cutting Tools 6149-M18X1.5-ID Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS 6149-M18X1.5-ID is a porting tool reamer designed for preparing ISO 6149-1 and SAE J2244-1 compliant hydraulic port faces on M18x1.5 metric fine threaded ports. It produces a 1.185-inch (30.10 mm) spotface diameter with a 15-degree seal angle required for O-ring face seal (ORFS) and boss-style port connections. The tool features 4 straight flutes with a bright, uncoated finish and is used by hydraulic system technicians, fluid power specialists, and precision machinists working on manifolds, cylinders, and hydraulic component housings.

This reamer is applied when reconditioning or preparing port faces on hydraulic components where a clean, flat spotface is critical to achieving a leak-free O-ring seal. It is suited for use in production and repair environments where M18x1.5 ports are machined to ISO 6149-1 and SAE J2244-1 standards. The tool accepts a 3/4-inch shank and is compatible with standard drill press, milling machine, or CNC setups. Minimum pilot diameter is 0.6496 inches with a maximum pilot diameter of 0.7815 inches.

Key Features

• 1.185-inch spotface diameter meets ISO 6149-1 and SAE J2244-1 port face requirements
• 15-degree seal angle for proper O-ring boss and face seal seating
• 4 straight flutes for clean material removal and accurate spotface geometry
• Identification groove included for quick standard identification during setup
• Bright, uncoated finish suitable for use with cutting fluid on ferrous and non-ferrous materials
• 3/4-inch shank diameter fits common drill press and milling machine toolholders

Compatibility

Designed for M18x1.5 metric fine threaded hydraulic ports conforming to ISO 6149-1 and SAE J2244-1 standards. Suitable for use on hydraulic manifolds, cylinders, and component housings requiring a 1.185-inch spotface diameter and 15-degree seal angle.

Installation Notes

This tool is installed and operated by machinists or fluid power technicians using a drill press, milling machine, or CNC machine with a compatible 3/4-inch toolholder. Always secure the workpiece firmly before operation and use an appropriate cutting fluid to extend tool life and ensure a clean spotface finish. Power down and lock out all equipment before changing or inspecting tooling. Verify port thread size and spotface diameter requirements against the component drawing before use.
