• Start with first choice recommended cutting data
• All cutting data recommendations are given without precision coolant
• Increase speed by 30-50% when applying precision coolant
• In parting off and external grooving CoroCut® 1-2 is a cost-efficient solution to depths where the 2-edged inserts can be used.

If CoroCut 1-2 doesn’t suit your needs, see Parting and grooving tools page for more tool recommendations.

Undercutting with CoroCut® 1-2

CoroCut® 2-edged inserts offer great chip control in undercutting operations with small clearance depths at low feeds.

• -RM is an all-round geometry for profiling in all materials
• Use the -RO geometry for operations in stainless steel, HRSA and other sticky materials

Circlip grooving

For low cutting forces and good surface quality, use CoroCut® 1-2 with -GF geometry
