Indexable Milling Tool Leaves a Smooth Surface Finish

The new Edge² DSS system from Dapra is designed to deliver both 90-degree milling performance and good value for an indexable milling product. Double-sided DSS inserts provide four usable cutting edges to lower cost per edge versus single-sided inserts. Additionally, Dapra’s permanent automatic cutter replacement program is intended to make it easier for shops to keep good-condition tools in use rather than making do with worn-out cutters.

The inserts feature a positive geometry for low cutting pressure and maintained strength. Convexity creates smooth surface finishes during step-down profile milling, and a custom-designed wiper edge generates good surface finishes, the company says. These inserts are available in both T-land and dished geometries in a variety of high-performance grades and coatings.

DSS end mills, shell mills and screw-on modular heads are machined from hardened, high-shock tool steel to minimize runout and maximize durability and life. Nickel plating provides a harder casing for improved pocket durability and resistance to chip galling, while deep gullets deliver efficient chip evacuation, even on the heaviest cuts, the company says. Long-reach tools are available with carbide cores for enhanced rigidity and reduced deflection.
