Value Collection H49R-6 Porting Tool Hss 4 Flutes

Product Description

The VALUE COLLECTION H49R-6 is a high speed steel porting tool designed to machine and finish O-ring boss ports to precise aerospace and military dimensional standards. It combines a reamer pilot with a spotface cutter in a single tool, allowing technicians to create a correctly sized, flat-bearing surface and port thread prep in one operation. With a 1.012-inch spotface diameter, a 0.506-inch minimum pilot diameter, and a 9/16-18 thread port size, it delivers consistent results on tubing connections requiring a leak-free, flat-seated port face. The 4-flute geometry provides clean cutting action on a range of workpiece materials.

This porting tool is intended for use in hydraulic, pneumatic, and fluid-system fabrication and maintenance work where O-ring boss ports must conform to MS 33649 and related standards. It is sized for 3/8-inch OD tube connections and suits work on abrasive materials, ferrous metals, and non-ferrous metals. Typical applications include aerospace maintenance, military equipment overhaul, and industrial hydraulic line assembly where port geometry tolerances are critical. It is used by machinists, tool and die technicians, and fluid-system mechanics.

Key Features

• 1.012-inch spotface diameter for accurate O-ring boss port facing
• Reamer pilot type with 0.506-inch minimum pilot diameter for self-centering alignment
• 9/16-18 straight thread port size per MS 33649 and AND 10050 military specifications
• 4-flute high speed steel construction handles ferrous metals, non-ferrous metals, and abrasive materials
• 1/2-inch straight shank fits standard milling machine and drill press collets and chucks
• Bright finish, no identification groove, 3-11/16-inch overall length

Compatibility

Designed for use on tube workpieces with 3/8-inch outside diameter requiring a 9/16-18 straight-thread O-ring boss port machined to AND 0.505, AND 0.511, AND 10050, and MS 33649 standards.

Installation Notes

This tool is installed in a drill press, milling machine, or similar rotating spindle using a collet or chuck sized for the 1/2-inch straight shank. Secure the workpiece firmly before beginning the operation and ensure proper cutting fluid or lubrication is applied when working ferrous metals. Verify port geometry against the applicable standard after machining. This is a precision cutting tool and should only be operated by qualified machinists or technicians familiar with porting tool procedures.
