Scientific Cutting Tools 6149-M22X1.5-ID Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS 6149-M22X1.5-ID is a porting tool reamer designed to machine O-ring boss (ORB) port faces to the precise dimensional requirements of ISO 6149-1 and SAE J2244-1 standards. It produces a flat spotface and pilot bore at M22x1.5 metric fine threaded ports, creating the seating surface needed for proper O-ring seal engagement. The tool features 4 straight flutes, a bright finish, and a 15-degree seal angle. Machinists, hydraulic system technicians, and fluid power specialists use this tool when preparing or refacing ports on manifolds, valve bodies, and hydraulic components where leak-free O-ring boss connections are required.

This reamer is suited for port preparation work on hydraulic and pneumatic manifolds, cylinders, valve blocks, and similar fluid power components that use M22x1.5 metric fine ORB ports. It is applied in both production machining environments and field or shop repair situations where an existing port face must be refaced to restore proper O-ring seating geometry. The identification groove confirms correct tool selection at the point of use. A 3/4-inch shank diameter allows mounting in standard collet chucks, end mill holders, or drill press spindles.

Key Features

• Spotface diameter of 1.3425 inches (34.10 mm) conforms to ISO 6149-1 and SAE J2244-1 port geometry requirements
• Reamer pilot type with minimum pilot diameter of 0.8071 inches (20.50 mm) and maximum pilot diameter of 0.9390 inches for precise bore engagement
• 15-degree seal angle machines the correct O-ring boss seat geometry for leak-free connections
• 4 straight flutes with bright finish for clean, accurate cutting on steel and similar materials
• Identification groove for fast, reliable tool verification before use
• 3/4-inch shank diameter compatible with standard machine toolholders

Compatibility

Designed for use on M22x1.5 metric fine O-ring boss ports conforming to ISO 6149-1 and SAE J2244-1 standards. Suitable for port preparation and refacing on hydraulic manifolds, valve bodies, cylinders, and fluid power components that use this port thread size and standard.

Installation Notes

This tool is intended for use by machinists or hydraulic technicians in a machine shop or controlled maintenance environment. Always depressurize and isolate any hydraulic or pneumatic system completely before performing port work. Secure the tool in a rigid, properly sized toolholder to prevent runout, which can compromise spotface geometry and O-ring sealing. Verify port thread size and standard compliance before selecting and applying the tool.
