Iscar 6402560 Grooving Insert Cbn 5mm Neutral Cut-grip

Product Description

The ISCAR 6402560 is a cubic boron nitride (CBN) grooving insert in the Cut-Grip series, designed for precision grooving operations on hard and difficult-to-machine materials. This neutral-hand insert carries the GITM500K040 insert style and IB50 manufacturer grade. The uncoated CBN substrate delivers thermal stability and edge hardness suited for interrupted cuts and hardened workpieces. With a cutting width of 5 mm (0.1969 inches) and a maximum depth of cut of 0.50 mm (0.0197 inches), it is built for shallow, controlled grooving passes. A corner radius of 0.40 mm (0.0157 inches) and a 7-degree positive rake angle support clean, low-force cutting action. Licensed machinists and CNC turning specialists are the primary installers of this insert.

This insert is intended for grooving applications on cast iron and hard materials, corresponding to workpiece material codes H and K per ISO 13399 classification. The Cut-Grip series is a common platform in production turning and CNC lathe environments, including both light manufacturing and high-volume shops requiring consistent groove geometry. The IB50 CBN grade is suited for dry or minimal-coolant finishing passes on hardened ferrous components where carbide tooling loses edge life. The positive rake geometry and 20-degree lead angle help manage cutting forces on rigid setups. This insert is a non-catalog stocking item with a minimum order quantity of one piece.

Key Features

• Cubic boron nitride (CBN) substrate, uncoated bright finish, for hardened and cast iron workpieces
• 5 mm cutting width (0.1969 inches) with a maximum depth of cut of 0.50 mm (0.0197 inches)
• Corner radius of 0.40 mm (0.0157 inches) for controlled groove profile
• 7-degree positive rake angle and 20-degree lead angle reduce cutting forces on rigid setups
• Neutral hand orientation compatible with standard Cut-Grip toolholders
• Compliant with ISO 13399 insert identification standards

Compatibility

Designed for use in ISCAR Cut-Grip series toolholders that accept GITM-style inserts. Suited for grooving cast iron and hard materials (ISO material codes H and K) on CNC turning centers and manual lathes with rigid setups. Specific holder compatibility should be confirmed against ISCAR Cut-Grip toolholder documentation for the GITM insert style.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer torque and clamping guidelines for the Cut-Grip system. Always index or replace worn inserts with the machine fully stopped and locked out per your facility lockout/tagout procedures. Do not exceed the stated maximum depth of cut range of 0.00 to 2.00 mm to avoid insert fracture. Inspect the pocket and clamping mechanism for chips or debris before seating a new insert.
