Carbide grooving insert DGN-UT/UA

for stainless steelfor steel

Product
A chipformer insert designed for low-feed parting and grooving. Recommended for Cr-Ni alloys and low-carbon steels, particularly in the bearing industry and similar problematic materials. The narrow chipformer geometry produces short, deformed chips for controlled chip evacuation.

Summary
Double-sided inserts for parting and grooving of Cr-Ni alloys, low-carbon steel and ductile materials at low feeds.

Applications

• Parting
• External grooving
• Face grooving
• Face grooving along shaft
• Internal face grooving
