Sandvik Coromant 5755708 Turning Insert VBMT332-MM 1105

Product Description

The SANDVIK COROMANT 5755708 is a solid carbide turning insert designed for precision external turning operations on CNC lathes and turning centers. Designated VBMT332-MM 1105, it carries a 35-degree diamond shape (V) with a 5-degree relief angle and a neutral hand orientation, making it suitable for both right- and left-hand tool holders configured for that geometry. The insert measures 0.6223 inches in length with a 3/8-inch inscribed circle and a 1/32-inch corner radius. The 1105 grade substrate is applied with a PVD TiAlN coating, delivering wear resistance and thermal stability during medium to finishing cuts in steel and related materials.

This insert is intended for use in the Sandvik Coromant CoroTurn 107 series tooling system, which is commonly deployed in production turning of steel components in both light manufacturing and heavy-volume machining environments. The MM chip breaker geometry is optimized for medium turning conditions, helping manage chip formation across a range of feed rates and depths of cut. It is typically installed by machinists and CNC tooling technicians in job shop, production floor, and precision machining settings. Compatible tool holders accept the VBMT insert style with screw-type clamping and the standard VBMT 16 04 08 ISO code geometry.

Key Features

• 35-degree diamond insert shape (V) with 5-degree relief angle for clearance in tight profiling and finishing passes
• PVD TiAlN coating on 1105 carbide grade for extended tool life in steel and stainless steel applications
• MM chip breaker geometry suited to medium turning operations with consistent chip control
• Neutral hand orientation compatible with appropriately configured right- and left-hand holders
• Screw-type insert holding method for positive, repeatable clamping in CoroTurn 107 series tool bodies
• Two cutting edges per insert for cost-effective tooling use

Compatibility

Designed for use in Sandvik Coromant CoroTurn 107 series tool holders accepting VBMT-style inserts with screw clamping. ISO code VBMT 16 04 08-MM 1105. Primary workpiece material is steel (ISO P); secondary workpiece materials include steel, stainless steel, superalloy, and titanium (ISO codes P, M, S).

Installation Notes

Insert seating and replacement should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and the spindle locked out per applicable lockout/tagout procedures. Ensure the insert pocket and clamping screw are clean and free of chips before seating the insert. Use the correct torque driver for the clamp screw as specified by the tool holder manufacturer. Do not exceed the recommended depth of cut or feed rate for the 1105 grade and MM geometry combination.
