Product Name: Hand Coning Tool Assembly (9/16″) – Part No. 05108840

Description:
This component is a manual hand coning tool assembly specifically designed for preparing 9/16 inch (0.56) high-pressure stainless steel tubing ends in waterjet cutting systems . According to the official parts diagram for High Pressure Coning Tools (Table 12-36), this assembly is listed as Item 2 for the .56 (9/16 inch) size .

The hand coning tool functions as a precision mechanical device that machines the critical 60-degree cone seat onto the end of 9/16 inch high-pressure tubing . The included angle of the cone is approximately 57 to 59 degrees . This cone surface is essential for creating a leak-free, metal-to-metal seal when the tube is assembled with a standard high-pressure gland nut and coned insert. High-pressure tubing must be both coned and threaded prior to installation .

The tool features a collet system that maintains perfect concentricity between the tube and the cutting blade, ensuring accurate and repeatable cone geometry . This hand-operated version provides greater control and is ideal for field service and maintenance applications where power tools may not be available. The cutter and collet are interchangeable on all of the assemblies to permit changing from one size tubing to another .

This assembly is designed for preparing 9/16 inch stainless steel tubing for coned-and-threaded (FT) connections capable of withstanding pressures up to 60,000 psi (4,137 bar) .

Applications:

• Cutting the 60-degree cone seat on 9/16 inch high-pressure tubing ends for waterjet systems

• Essential for fabricating custom-length high-pressure lines and maintaining the fluid system of a waterjet cutting machine 

• Suitable for preparing tubing for systems operating at pressures up to 60,000 psi (4,137 bar) and higher

• Ideal for field service, maintenance, and workshop environments

• Compatible with KMT, AccuStream, Flow, OMAX, BFT, WSI, and other standard waterjet systems 

Features:

• Precision Collet System: Maintains perfect concentricity between the tube and cutting blade, ensuring accurate and repeatable cone geometry 

• Replaceable Blade Design: The cutting blade is a consumable component that can be replaced when dull, extending the life of the tool

• Manual Operation: Hand-powered design provides greater control compared to power tools, ideal for field service and precise work 

• Durable Construction: Made from hardened tool steel components designed to withstand repeated use on work-hardened stainless steel tubing 

• Complete Assembly: Includes all necessary components: collet, collet nut, body, feed nut, cutter support, and cutting blade

• Interchangeable Components: Cutter and collet can be interchanged to permit changing from one size tubing to another 

Maintenance:

Usage Guidelines:

• Proper Setup: Place the body of the coning tool in a vise with soft jaws, allowing adequate clearance for rotation of the cutter handle. Position the tool so the handle is elevated slightly to allow lubricant to flow to the cutting blade 

• Tube Preparation: Cut tubing to the proper length, allowing extra length for engagement into the connection. Deburr the ends of the tubing before starting . Refer to engagement allowance tables (0.86 inches for 9/16″ HP tubing) 

• Positioning Procedure: Rotate knurled cap clockwise into tool as far as it will go, then back off the knurled cap by rotating counterclockwise a number of complete rotations. For 9/16″ O.D. tubing, back off 8 turns initially and cut for 7 1/2 turns to complete the cone 

• Secure the Tube: Loosen the gland nut, insert tubing through the collet until the tubing stops against the inside cutter, then tighten the collet nut to secure the tubing into position 

• Use Cutting Oil (Critical): Apply a liberal amount of medium-weight cutting oil with high sulfur content to the exposed end of the tubing, the cutting blade, and through the lubrication channel. Apply lubricant frequently and liberally throughout the cutting operation 

• Proper Cutting Technique: Rotate handle clockwise fairly rapidly with one hand while slowly rotating the knurled cap clockwise with the other hand to continuously feed the cutter into the tubing. Do not overly force the cutter against the tubing as it will bind . For 9/16″ O.D. tubing, this size requires the most amount of firmness in the cutting 

• Chip Removal: Before interrupting the cut, back the cutting blade away from the tubing. Use compressed air or a small brush to remove accumulated chips from the blade and tubing throughout the operation 

• Completion: Continue operation until the blade begins to cut the land area at the base of the cone. Turn the handle several more rotations to face-off the end of the cone 

Inspection & Care:

• Clean After Use: Clean machining chips from the blade and collet before coning the next tube. Thoroughly clean the entire tool assembly after each use to prevent rust and maintain precision 

• Inspect Blade for Wear: Regularly inspect the cutting edges of the blade. If the blade requires excessive force, produces a rough surface finish, or fails to cut a complete 360-degree cone, replace it immediately

• Blade Replacement: When the blade becomes dull, replace it with a new OEM blade. Do not attempt to sharpen the blade, as this can alter its critical geometry and lead to improper cone angles and potential high-pressure leaks

• Check Collet and Nut: Inspect the collet and gland nut for wear or damage. A worn collet will not hold the tubing securely, resulting in off-center cones. If a collet sticks after the collet nut has been released, tap the side firmly with a wrench to release it 

• Storage: Store the complete tool set in a clean, dry, protective case to prevent damage to precision components

• Full Depressurization (Critical): This tool is for preparing new or replacement tubing offline. Never use it on a pressurized system. Always follow lockout/tagout procedures and ensure the waterjet system is fully depressurized before any maintenance
