Sandvik Coromant 5730444 Turning Insert 55 Diamond H13A

Product Description

The SANDVIK COROMANT 5730444 is a solid carbide turning insert designed for precision metal cutting operations on CNC and manual turning centers. Identified by ISO code DCGT 11 T3 01-UM H13A, it features a 55-degree diamond insert shape, a 3/8 inch inscribed circle, and a 0.1 mm (0.0039 inch) corner radius. The uncoated H13A carbide grade delivers sharp, consistent edges well suited to finishing and light turning passes. The UM chip breaker geometry promotes controlled chip flow at low depths of cut. This insert is sold individually but requires a minimum order quantity of 10 units per transaction.

This insert is intended for turning applications on steel as the primary workpiece material and stainless steel as the secondary workpiece material. It belongs to the CoroTurn 107 series, which is engineered for small-part turning, profiling, and bore turning where close tolerances and fine surface finishes are required. The neutral hand orientation makes it compatible with both conventional and back-turning setups. It is typically installed by machinists and CNC operators in production and job-shop environments handling precision turned components.

Key Features

• 55-degree diamond insert shape (code D) for tight-profile and contour turning capability
• H13A uncoated solid carbide grade optimized for sharp-edge finishing on steel and stainless steel
• UM chip breaker geometry for controlled chip evacuation at light cutting parameters
• 0.1 mm corner radius minimizes workpiece stress during fine finishing passes
• Screw-holding method provides secure, repeatable insert clamping in compatible toolholders
• 2 cutting edges per insert for extended tooling value per unit

Compatibility

Designed for use in CoroTurn 107 series toolholders that accept DCGT-style inserts with a screw-clamp holding method. Primary workpiece material is steel (ISO code P); secondary workpiece material is stainless steel (ISO code M). ISO code DCGT 11 T3 01-UM H13A and catalog number DCGT11T301UMH13A apply for cross-reference to compatible holder specifications.

Installation Notes

Installation is performed by machinists and CNC tooling technicians. The machine spindle must be fully stopped and the turret or toolpost must be locked before replacing or indexing inserts. Use the manufacturer-specified torque driver for the clamping screw to avoid seat damage or insert fracture. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
