Scientific Cutting Tools MS33649-24R Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS MS33649-24R is a porting tool reamer designed for precision spotfacing and tube porting operations in aerospace and hydraulic tubing systems. It produces a 2.628-inch spotface diameter and is sized for 1-1/2-inch tube outside diameter (Tube Dash 24) applications. The reamer pilot type ensures accurate centering and clean face geometry on tube fittings. With 4 straight flutes and a bright finish, it delivers consistent material removal on metallic workpieces. The tool meets AS 5202 and MS 33649 standards and weighs 2.0625 pounds.

This porting tool is used when preparing tube fitting ports to MS 33649 and AS 5202 specifications, common in aerospace hydraulic and pneumatic plumbing systems. It is appropriate for shop or field use where tube end preparations require a controlled spotface and reamed pilot bore. The 30-degree seal angle geometry is matched to the standard flared or flareless fitting interface used in these systems. Machinists and aerospace plumbing technicians performing tube assembly work are the primary installers.

Compatibility

Designed for use on tube workpieces conforming to AS 5202 and MS 33649 porting standards, Tube Dash 24 (1-1/2-inch OD). Confirm port and pilot diameter tolerances against application drawings before use.

Installation Notes

This tool is intended for use by machinists or qualified aerospace plumbing technicians familiar with AS 5202 and MS 33649 porting procedures. Secure the workpiece firmly before operation and verify pilot fit within the specified minimum and maximum pilot diameter range. Use appropriate cutting fluid for the workpiece material to maintain tool life and surface finish quality. Always inspect the spotface and pilot bore dimensions with calibrated gauging after completing the porting operation.
