Accupro 75264549 Turning Insert DCMT21.51 Carbide Cvd

Product Description

The ACCUPRO 75264549 is a DCMT-style carbide turning insert designed for precision external turning operations on steel and stainless steel workpieces. It carries ANSI insert code DCMT21.51 and ISO insert code DCMT070204. The insert features a 55-degree diamond (rhombic) shape with a 7-degree relief angle and a 0.40 mm (0.0157 inch) corner radius. Grade ACM20P with a CVD coating delivers high wear resistance across a range of cutting conditions from moderate to aggressive material removal. Neutral hand orientation makes it suitable for a broad range of tool holder setups. It is sold individually with a minimum order quantity of 10.

This insert is intended for turning operations on steel (ISO P) and stainless steel (ISO M) materials in CNC and manual lathe applications. The WSF+ chip breaker geometry supports light to medium finishing and semi-finishing passes. It is commonly used in production machining environments, toolrooms, and job shops where consistent surface finish and dimensional accuracy are required. Machinists and CNC operators installing these inserts should verify holder compatibility against the DCMT insert style and ANSI size code DCMT21.51 before use.

Key Features

• ANSI code DCMT21.51 and ISO code DCMT070204 for direct cross-reference ordering
• CVD-coated Grade ACM20P carbide for high wear resistance on steel and stainless steel
• 55-degree diamond insert shape with positive side clearance for reduced cutting forces
• WSF+ chip breaker geometry suited to finishing and semi-finishing applications
• Screw-holding method with 0.1102 inch hole diameter for secure insert retention
• Maximum depth of cut of 1.80 mm (0.0709 inch) for controlled material removal

Compatibility

Designed as a direct replacement for DCMT21.51 and DCMT070204 style insert seats. Compatible with tool holders specified for DCMT insert style, positive clearance code C, tolerance code M, and ANSI size code 21.51. Verify holder specifications before ordering.

Installation Notes

Installation is performed by CNC machinists or manual lathe operators with standard insert-seating tools and a torque wrench appropriate for the tool holder manufacturer's screw specification. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and seating surface for chips or debris before placing the new insert. Do not exceed the recommended maximum depth of cut for the grade and chip breaker combination.
