SCARFING INSERT_SNMA 1506-R
Caution
Product Description
Double-sided negative scarfing insert SNMA 150608-R09:6640 from DORMER PRAMET with a flat top face and 8 cutting edges. Its 9 mm working radius removes the external weld bead from welded steel and stainless-steel tubes and pipes with an outside diameter of 13-16 mm.
Grade 6640
- WC-Co carbide substrate without cubic carbides
- Thin MT-CVD coating with a TiCN supporting layer
- ISO application range P20-P40 (steel) and M20-M35 (stainless steel)
- Intended for semi-roughing and roughing at lower to medium cutting speeds
- Suitable for interrupted cuts and unfavourable machining conditions
Usage guidance
- Choose the insert by tube outside diameter: SNMA 150608-R09 is intended for tubes of 13-16 mm.
- Use a scarfing tool holder that accepts SNMA 1506 inserts and clamp the insert securely. Stable clamping prevents insert vibration and helps achieve a clean scarfed surface.
- Index to a new cutting edge when wear or chipping appears. The double-sided design provides 8 cutting edges.
- Carbide edges are sharp and scarfing chips are hot. Wear gloves and eye protection when handling inserts and chips.
The DORMER PRAMET SNMA 1506-R series consists of double-sided, negative scarfing inserts for external scarfing, the removal of the weld bead (weld deposit) from the outside of welded tubes and pipes during tube production. The square insert has a flat top face and 8 cutting edges, and each cutting edge is ground to a working radius that follows the tube contour.
SNMA 150608-R09:6640 has a working radius of 9 mm and covers tubes with an outside diameter of 13-16 mm. It is made in grade 6640, an MT-CVD coated WC-Co carbide within ISO ranges P20-P40 and M20-M35, for scarfing steel and stainless-steel tubes.
Key features
- Double-sided negative design with 8 cutting edges per insert
- Flat top face (SNMA 1506-R insert design)
- 9 mm working radius matched to tube outside diameters of 13-16 mm
- Precise cutting edge for a high-quality surface on the scarfed weld area
- Tough coated carbide grade with excellent resistance to heat and chipping for long edge life
Applications
External weld scarfing on tube and pipe mills producing welded steel and stainless-steel tubes.

How to choose a scarfing insert
- Tube outside diameter: pick the working radius (PFRAD) whose tube diameter range covers the tube being produced. SNMA 150608-R09 covers 13-16 mm.
- Insert top form: SNMA 1506-R has a flat top face, while the SNMX 1507-R series has a concave top face. Both are double-sided negative inserts with 8 cutting edges.
- Workpiece material: grade 6640 is intended for steel and stainless-steel tubes.
