Tube End Finishing Rotary Tools

For manufacturing of tubing products, or those who manufacture products with tubing components, Severance Tool has developed a line of tube end finishing rotary tools which can deburr, form or chamfer as required by application needs. The tools are finish both the inside diameter and outside diameter of tubing ends in a single operation and many feature adjustable, two piece construction to accommodate work on same size tubing having varying wall thickness ranges. Other features may include, depending upon the application, the company's Chatterless tooth geometry that alternates tooth-cutting angles to eliminate resonant vibration from the tool and workpiece for smooth finishes, and Severance’s exclusive Grayhone finish that provides cutting edges ready to work with no break in period required.

Among the tools offered, is a full line of tube deburring tools available in HSS or carbide construction. These tools, although they provide a 30° inside chamfer and a 45° outside deburring are designed for light duty – to break sharp edges of both the inside and outside diameters simultaneously. They feature tooth geometry with a shearing cutting action for fast cutting that prevents loading of chips. These tools can be reground numerous times for long service and operate in speed ranges of 50 to 200 rpm. The outside ring or member is adjustable, secured by screws, to provide various outside edge break sizes and compensate for different wall thickness within a given tube diameter range. Tube deburring cutters are available in standard sizes for 1/8” outside diameter (1/16” inside diameter) through 2-1/4” outside diameter (2” inside diameter) tubing, and with a variety of shank styles.

Tube end chamfer mills provide the same shear cutting action and outside ring adjustable as the deburring cutters, plus with Chatterless angle geometry are for heavy-duty cutting to machine precise, smooth 45° outside diameter and 30° inside diameter chamfers in applications requiring easy assembly with other components. Chamfering mills are available in sizes for pipe and tubing ranges from 3/16” to 2-1/2” outside diameter.

The tube end forming cutters machine both an inside diameter and outside diameter radius, establishing a smooth, rounded end that is ideal for applications where tubing may be exposed. A selection of HSS and carbide tools are available in sizes for tubing ranging from 1/8” to 2-1/2” outside diameters – each outside diameter size is complemented by a range of wall thickness or gauge sizes to accommodate most popular tubing applications.

For all three types of tube end finishing tools, standard sizes are typically shipped with same-day services. Severance also provides application-specific design and manufacture service, including custom size, chamfer angles, and forming characteristics. Single cutting action (inside diameter or outside diameter) chamfering tools are also available, and Severance offers a range of tool styles and sizes for deburring holes through tube walls.
