Scientific Cutting Tools 6149-M27X2.0-ID Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS 6149-M27X2.0-ID is a porting tool reamer designed for machining ISO 6149-1 and SAE J2244-1 compliant hydraulic port faces. It produces a precise spotface with a 1.5787 inch (40.10 mm) diameter on M27x2.0 metric fine threaded ports, ensuring the seating surface meets the dimensional requirements for O-ring face seal (ORFS) and boss port connections. The tool features a 4-flute straight flute geometry with a bright finish and a 15-degree seal angle. Machinists and hydraulic system assemblers use this tool during port preparation on manifolds, cylinders, and hydraulic components where port face integrity is critical to leak-free assembly.

This porting tool is suited for use on hydraulic components, fluid power manifolds, and machined housings requiring M27x2.0 port thread sizes per ISO 6149-1 and SAE J2244-1 standards. It is intended for use in production and maintenance machining environments where accurate spotface depth and concentricity are required. The integrated reamer pilot guides the tool into the existing port bore to maintain alignment during the spotfacing operation, making it appropriate for both CNC and manual machining setups.

Key Features

• 1.5787 inch (40.10 mm) spotface diameter for M27x2.0 metric fine ports
• Reamer-type pilot with 0.9843 inch minimum and 1.1595 inch maximum pilot diameter for bore alignment
• 4-flute straight flute design for controlled chip evacuation and surface finish
• 15-degree seal angle matches ISO 6149-1 and SAE J2244-1 port face requirements
• Identification groove included for quick tool recognition at the machine
• Bright finish, uncoated carbide or HSS construction for consistent dimensional performance

Compatibility

Designed for machining M27x2.0 metric fine hydraulic ports conforming to ISO 6149-1 and SAE J2244-1 standards. Suitable for use on hydraulic manifolds, cylinders, and ported components where these port standards are specified.

Installation Notes

This tool is installed and operated by machinists in CNC machining centers or manual milling setups. Power down and lock out all equipment before tool changes. Use appropriate cutting fluid for the workpiece material to maintain tool life and surface finish quality. Verify port bore diameter falls within the pilot diameter range of 0.9843 to 1.1595 inches before use to ensure proper piloting and avoid tool deflection.
