Scientific Cutting Tools MS33649-16R Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS MS33649-16R is a porting tool reamer designed to machine O-ring boss port faces on hydraulic and fluid system fittings to the AS 5202 and MS 33649 standards. It produces a 1.965-inch spotface diameter with a 30-degree seal angle and 4 straight flutes for clean, accurate seating surfaces. Compatible with 1-inch OD tubing (Tube Dash 16), it features a reamer-style pilot with a minimum pilot diameter of 1.235 inches and a maximum of 1.3385 inches, keeping the tool centered during the cut. Machinists and fluid system technicians use this tool wherever precision boss porting is required per aerospace and industrial fluid power specifications.

This porting tool is suited for aerospace, defense, and industrial hydraulic or pneumatic tube assembly applications where O-ring face seal and boss port geometry must conform to MS 33649 and AS 5202 standards. It is used to prepare port faces on manifolds, housings, and fittings that accept Tube Dash 16 connections with 1-inch OD tubing. The bright uncoated finish is appropriate for standard steel and aluminum workpieces typical in these systems.

Installation Notes

This tool is installed and operated by machinists or fluid system technicians using a drill press, milling machine, or appropriate rotary setup. Secure the workpiece firmly and ensure proper alignment before engaging the pilot. Follow shop-standard speeds and feeds for the workpiece material; no specific values are listed for this tool in the available data. Deburr and clean the finished port face before assembling O-ring boss fittings.
