OD Scarfing Insert – S-SPUB
Scarfing inserts are specialized carbide cutting tools used in machining operations, particularly for tube and pipe scarfing. This process involves removing burrs, weld seams, or excess material from the outer diameter (OD) of tubes or pipes after welding, ensuring a smooth finish for further processing like coating or assembly. These inserts are typically indexable (multi-sided for extended use) and designed for high-speed, high-volume production in industries like oil & gas, automotive, and manufacturing.

Industrial Benefits
- High cutting precision: Produces smooth tube surfaces for downstream processing.
- Extended tool life: Carbide + coating resists heat and abrasion in continuous production.
- Versatility: Compatible with various scarfing holders and tube diameters.
- Shape & Geometry: Square inserts with relief angles, typically featuring four cutting edges.
- Material: Made from tungsten carbide, often with CVD multilayer coatings to resist thermal shock and wear.
- Radius Options: Available in a wide range (e.g D10 to D76), matched to pipe outer diameters.
- A common rule: select a radius between 110% and 150% of the tube OD.
- Models: Includes variants like S-SPUB-63A to S-SPUB-63T, each with specific dimensions and cutting profiles.
