Product Name: Collet, .38 (3/8″ High-Pressure Coning Tool Component) – Part No. 05108964

Description:
This component is a precision collet specifically designed for use with 3/8 inch (.38) high-pressure hand coning tool assemblies in waterjet cutting systems . According to the official parts diagram for High Pressure Coning Tools (Table 12-36), this collet is a standard component for the .38 (3/8 inch) size.

The collet functions as a critical clamping and alignment component within the hand coning tool assembly (P/N 05108857). Its primary purpose is to securely hold and center the 3/8 inch high-pressure stainless steel tubing during the cone machining (coning) process. The collet ensures perfect concentricity between the tube and the cutting blade, which is essential for producing an accurate, concentric 60-degree cone seat on the tube end. This precision cone surface is necessary for creating a leak-free, metal-to-metal seal when the tube is assembled with a standard high-pressure gland nut and coned insert.

Applications:

• Securely clamps and centers 3/8 inch high-pressure tubing during the coning operation

• Used as a component of the Hand Coning Tool Assembly (.38, P/N 05108857)

• 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

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

Features:

• Precision Machined: Manufactured to exacting tolerances for a secure and accurate fit with 3/8″ high-pressure tubing

• Hardened Tool Steel Construction: Made from durable, hardened steel to withstand repeated use on work-hardened stainless steel tubing

• Concentric Clamping: Ensures perfect tube centering for accurate cone geometry

• Part of a Standardized Kit: This collet (05108964) is the designated component for the .38 size in the High Pressure Coning Tools table (Item 2)

• Interchangeable: Can be used with various coning tool assemblies that accept .38 size collets

• Corrosion-Resistant: Designed to withstand exposure to cutting oils and workshop environments

Maintenance:

Usage Guidelines:

• Use as a Matched Set: For best results, always use the collet as part of the complete, matched hand coning tool assembly (P/N 05108857)

• Proper Tube Preparation: Cut tubing to the proper length and deburr the ends before inserting into the collet

• Proper Seating: Ensure the tubing is fully inserted through the collet until it contacts the stop or is correctly positioned, then securely tighten the collet nut

• Use Cutting Oil (Critical): Always apply cutting oil to the tube end and blade during the coning process. This lubricates the cutting action, prevents galling of the stainless steel, and extends the life of both the collet and cutting blade

• Proper Extension Length: For 3/8″ tubing, the recommended extension length beyond the collet is as specified in the equipment service manual

Inspection & Care:

• Inspect for Wear: Regularly inspect the collet gripping surfaces for signs of wear, galling, or deformation. A worn collet will not hold the tubing securely, resulting in off-center cones and potential high-pressure leaks

• Clean After Use: After each use, thoroughly clean the collet of metal shavings, cutting oil, and debris to prevent rust and maintain precision. Use compressed air or a small brush to remove chips from the gripping surfaces

• Check for Damage: Inspect the collet for cracks or damage before each use; a damaged collet must be replaced

• Lubrication: Periodically lubricate the collet nut threads with light machine oil to ensure smooth operation

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

• Collet Release: If the collet sticks after the collet nut has been released, tap the side firmly with a wrench to release it

• 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
