Sandvik Coromant 5750786 Turning Insert SNMG644-MR 2035

Product Description

The SANDVIK COROMANT 5750786 is a SNMG-style indexable turning insert designed for external and internal turning operations on CNC lathes and turning centers. Manufactured from solid carbide with a TiAlN and TiN multilayer coating, this insert carries the 2035 grade designation and features an MR chip breaker geometry. The square insert shape (90-degree included angle) provides four usable cutting edges. With a 3/4-inch inscribed circle and a 1/16-inch corner radius, it is suited for medium to semi-finish turning passes where controlled chip formation and tool life are the primary concerns. Licensed machinists and CNC operators handling production turning work are the primary users of this insert.

This insert is applicable to general-purpose turning of steel and alloyed workpiece materials at moderate cutting depths and feed rates. The MR chip breaker is optimized for medium-range chip control, reducing chip entanglement and heat buildup at the cutting zone. It seats in SNMG-compatible toolholders using a clamp-and-pin holding method, making it a direct fit for standard square-insert turning tool bodies common in job shop and production environments. ISO code SNMG 19 06 16-MR 2035 identifies it within the ISO turning insert classification system.

Key Features

• SNMG square insert style with 90-degree included angle - four usable cutting edges per insert
• Solid carbide substrate with TiAlN and TiN coating for wear and heat resistance
• 2035 manufacturer grade - suited for medium turning of steel workpieces
• MR (G chip breaker) geometry for controlled chip formation in medium-feed applications
• 1/16-inch (0.0625-inch) corner radius for semi-finish to medium turning passes
• Clamp and pin holding method for rigid, repeatable seating in compatible toolholders

Compatibility

Designed for use in SNMG-compatible turning toolholders that accept a square insert with a 3/4-inch inscribed circle, 1/4-inch insert thickness, and a 0.312-inch hole diameter using clamp-and-pin retention. ISO designation SNMG 19 06 16-MR 2035 applies when cross-referencing toolholder catalogs.

Installation Notes

Insert installation should be performed with the machine spindle stopped and all power isolated per shop lockout/tagout procedures. Seat the insert fully into the toolholder pocket before tightening the clamp or pin to the toolholder manufacturer's specified procedure. Inspect the pocket for chips or debris before seating a fresh insert, as contamination will affect insert seating and surface finish. Insert indexing and replacement are typically performed by a machinist or CNC operator familiar with turning toolholder systems.
