Accupro 75259986 Ccmt Turning Insert Cvd Carbide

Product Description

The ACCUPRO 75259986 is a CCMT-style carbide turning insert designed for precision metal cutting on CNC and manual lathes. Featuring an 80-degree diamond (rhombic) shape with a 7-degree relief angle and a 0.20mm (0.0079 inch) corner radius, this insert delivers controlled chip formation across a range of ferrous workpiece materials. The CVD coating and ACP25M grade provide a balance of wear resistance and toughness suited for steel, stainless steel, and cast iron applications. The neutral-hand orientation and screw-holding method make it compatible with standard CCMT toolholders used in production turning and general machining operations.

This insert is intended for use in turning centers and lathe applications where consistent dimensional accuracy and surface finish are required. It is appropriate for both roughing and finishing passes within its maximum depth-of-cut rating of 1.80mm (0.0709 inch). The WSF+ chip breaker geometry supports reliable chip control across the rated workpiece material categories. Machinists and CNC programmers working with steel (P), stainless steel (M), and cast iron (K) workpieces will find this insert suited to high-wear-resistance demands as well as moderate toughness requirements.

Key Features

• CCMT insert style with 80-degree diamond (rhombic) shape and 7-degree positive relief angle
• CVD-coated ACP25M carbide grade for high wear resistance across steel, stainless, and cast iron
• WSF+ chip breaker geometry for controlled chip formation during turning operations
• 0.20mm (0.0079 inch) corner radius suitable for fine finishing and light profiling
• Maximum depth of cut 1.80mm (0.0709 inch) for controlled material removal
• Screw-holding method with neutral hand for use in standard CCMT toolholders

Compatibility

Designed as a direct-fit replacement for ANSI insert code CCMT21.50.5 (ISO CCMT060202) toolholders requiring a screw-lock, neutral-hand CCMT insert with a 0.25-inch inscribed circle and 0.0937-inch insert thickness.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Seat the insert fully in the toolholder pocket and torque the clamping screw using the appropriate insert wrench to ensure secure clamping without cracking the carbide substrate. Inspect the toolholder pocket for chips or debris before seating a new insert.
