Sandvik Coromant 7859093 Turning Insert CCMT32.53-PR 4415

Product Description

The SANDVIK COROMANT 7859093 is a solid carbide turning insert in the CoroTurn 107 series, designed for external and internal turning operations on CNC lathes and turning centers. The insert carries an 80-degree diamond shape (CCMT style) with a neutral hand orientation and a 1.19 mm (0.0469 inch) corner radius, making it well suited for general-purpose finishing and semi-finishing passes. The CVD-applied multilayer coating — TiCN, Al2O3, and TiN — provides a combination of wear resistance, heat resistance, and built-in wear detection. Licensed machinists and CNC operators in job shops and production environments use this insert for consistent, repeatable material removal.

This insert is primarily rated for ISO material group K (cast iron) as the primary workpiece material, with ISO group P (steel) as the secondary classification. It fits into standard CCMT-style toolholders using a clamp or screw holding method, making it a practical choice for shops running a wide range of ferrous materials on turning centers. The CoroTurn 107 series is engineered for light to medium depths of cut where surface finish and insert life consistency are priorities.

Key Features

• 80-degree diamond insert shape (CCMT) with 7-degree relief angle for positive cutting geometry
• CVD multilayer coating: TiCN base, Al2O3 thermal barrier, TiN top layer for wear indication
• 1.19 mm (0.0469 inch) corner radius for controlled surface finish on finishing passes
• Neutral hand orientation — compatible with right- and left-hand toolholder setups
• Chip breaker geometry (T) suited for light to medium turning chip control
• ISO designation CCMT 09 T3 12-PR 4415 for cross-reference with equivalent holders and inserts

Compatibility

Designed for use with standard CCMT-style turning toolholders using clamp or screw insert retention. The ISO code CCMT 09 T3 12-PR 4415 and manufacturers catalog number CCMT 3(2.5)3-PR 4415 can be used to verify holder and pocket compatibility. Suited for ISO K (cast iron) primary applications and ISO P (steel) secondary applications.

Installation Notes

Insert seating and clamping should be performed according to the toolholder manufacturer's torque and clamp specifications — do not use values from this listing, as none were provided. Ensure the insert pocket is clean and free of debris before seating to prevent rocking or premature edge failure. A licensed machinist or qualified CNC operator should verify feed rate, depth of cut, and cutting speed parameters against SANDVIK COROMANT published cutting data for grade 4415 before production use. Power down and lock out the machine spindle before any insert change.
