Scientific Cutting Tools 6149-M48X2.0 Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS 6149-M48X2.0 is a hydraulic port porting tool designed to finish-machine ISO 6149-1 and SAE J2244-1 metric fine-thread port faces. It combines a reamer-style pilot with a spotface cutter to produce a precise, flat sealing surface for M48x2.0 port threads. The spotface diameter is 2.248 inches (57.10 mm), the minimum pilot diameter is 1.811 inches (46.00 mm), and the tool runs 4 straight flutes with a bright finish. Machinists, hydraulic system fabricators, and maintenance technicians use this tool when reconditioning or preparing port faces on hydraulic manifolds, cylinders, and fluid power components.

This porting tool is suited for M48x2.0 metric fine-thread port applications in hydraulic and fluid power systems where ISO 6149-1 or SAE J2244-1 port geometry is required. Typical use cases include OEM manufacturing of hydraulic manifolds, field reconditioning of port faces on industrial cylinders, and repair of damaged sealing surfaces on mobile and stationary hydraulic equipment. The 15-degree seal angle and reamer pilot ensure repeatable geometry that meets standard port sealing requirements.

Key Features

• Spotface diameter of 2.248 inches (57.10 mm) for M48x2.0 port thread size
• Reamer-style pilot with minimum pilot diameter of 1.811 inches and maximum of 1.9862 inches for self-centering accuracy
• 4 straight flutes with bright coating for clean chip clearance and surface finish
• 15-degree seal angle conforms to ISO 6149-1 and SAE J2244-1 standards
• 1-inch shank diameter with 2.25-inch shank length for rigid tool holding
• No identification groove; metric fine thread type

Compatibility

Designed for use on M48x2.0 metric fine-thread hydraulic ports conforming to ISO 6149-1 and SAE J2244-1 standards on hydraulic manifolds, cylinders, and fluid power components.

Installation Notes

This tool is intended for use by qualified machinists or hydraulic system technicians operating a drill press, mill, or dedicated porting tool driver. Always depressurize and isolate hydraulic circuits completely before performing port face work. Secure the workpiece firmly and ensure the pilot is fully seated in the existing port thread before engaging the spotface cutter. Follow machine shop safety practices and consult the applicable ISO 6149-1 or SAE J2244-1 standard for required surface finish and dimensional tolerances.
