Iscar 6403054 Grooving Insert GFQR12-2.50-0.20 IC528

Product Description

The ISCAR 6403054 is a solid carbide grooving insert in the ChamGroove series, designed for external grooving and parting operations on CNC lathes and turning centers. It carries ISCAR grade IC528 with a PVD-applied TiCN and TiN finish, a combination engineered for high-temperature, abrasion-resistant cutting performance. The insert delivers a 2.5 mm cutting width and a maximum depth of cut of 3.0 mm. It features a neutral hand orientation and is held in place by clamp and screw. Machinists and CNC technicians working in precision metalworking environments install this insert for demanding grooving applications.

This insert is optimized for cutting superalloys and titanium, making it well-suited for aerospace, medical device, and high-performance industrial component production. The IC528 grade performs in the C5 and C6 material grade range, targeting ISO workpiece material codes M, P, and S. The GFQR insert style seats in compatible ChamGroove toolholders and is identified by insert size code 12-2.50-0.20. It is a single-use, non-full-radius insert with a 0.20 mm corner radius, suitable for precise groove geometry control on close-tolerance parts.

Key Features

• Solid carbide substrate with PVD TiCN and TiN multilayer coating for extended tool life in hard materials
• 2.5 mm cutting width for consistent groove sizing without secondary finishing
• Maximum depth of cut of 3.0 mm, within the 3.0 to 4.0 mm depth of cut range for this insert class
• 0.20 mm corner radius provides controlled edge geometry on superalloy and titanium workpieces
• Neutral hand orientation allows use in standard right-hand grooving setups
• Clamp and screw insert holding method ensures rigid, repeatable seating in the toolholder

Compatibility

Designed for use with compatible ISCAR ChamGroove series toolholders that accept the GFQR insert style in size 12-2.50-0.20. Manufacturer cross-reference number is GFQR 12-2.50-0.20. Conforms to ISO 13399 tooling data standards.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. The machine spindle must be fully stopped and the turret locked out before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer when tightening the clamp screw. Do not exceed the recommended depth of cut range for this insert to avoid insert fracture or premature edge failure.
