Expert Q&A
What are the primary applications for SM shape burrs?
The oval profile excels in mold making, die casting repairs, and complex contour work where both flat and curved surfaces need blending.
How does the oval shape compare to standard ball or cylinder shapes?
The SM shape combines the material removal rate of cylindrical burrs with the contouring ability of ball shapes, reducing tool changes.
What coolant recommendations do you have for these burrs?
For optimal performance, we recommend using water-soluble coolants at 5-8% concentration for most applications.
