Sandvik Coromant 5764761 Modular Grooving Head System Size 40

Product Description

The SANDVIK COROMANT 5764661 is a right-hand modular grooving head designed for use in the CoroCut 1-2 modular tooling system. It accepts N123 size G inserts, specifically the N123G2-0300-GM, and delivers a maximum depth of cut of 0.1575 inches (4.00 mm). The head features through-coolant capability, directing cutting fluid directly to the cutting zone to extend insert life and support continuous grooving operations. With a head length projection of 0.5512 inches (14.00 mm) and a center-to-cutting-edge distance of 1.7756 inches (45.10 mm), this head is built for precise, repeatable grooving on CNC lathes and turning centers. It is installed by machinists and tooling specialists in production and job-shop environments.

This modular grooving head is suited for external grooving applications on CNC turning centers where the CoroCut 1-2 system is in use. The right-hand cutting direction accommodates standard spindle rotation on most lathe configurations. It supports groove widths from 0.1181 inches (3.00 mm) minimum up to 0.7087 inches (18.00 mm) maximum, making it adaptable across a range of groove profiles. System Size 40 designates the coupling interface, which must match the corresponding CoroCut 1-2 shank or adaptor. This head is appropriate for both roughing passes and finish grooving where insert change-out speed and dimensional repeatability are priorities.

Key Features

• Right-hand cutting direction for standard CNC lathe spindle configurations
• Through-coolant design directs fluid to the cutting edge for improved chip evacuation and insert longevity
• Compatible with N123 size G inserts, including the N123G2-0300-GM
• Maximum depth of cut of 0.1575 inches (4.00 mm) for controlled grooving passes
• Groove width range of 0.1181 inches to 0.7087 inches (3.00 mm to 18.00 mm)
• Modular CoroCut 1-2 interface at System Size 40 for quick head changes without full tool disassembly

Compatibility

Designed for use within the CoroCut 1-2 modular tooling system at System Size 40. Compatible inserts include the N123 size G family, with confirmed compatibility for insert style N123G2-0300-GM. The coupling interface must match a CoroCut 1-2 System Size 40 shank or adaptor.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. The machine spindle must be fully stopped and the turret or tool station locked out before mounting or removing the grooving head. Secure the modular head to the corresponding CoroCut 1-2 adaptor per the tooling system assembly procedure, ensuring the coupling interface is clean and free of chips or burrs. Verify through-coolant passages are clear and that coolant pressure is within the machine and toolholder system specifications before resuming operation.
