Accupro 75262493 DNMG110404 Carbide Turning Insert

Product Description

The ACCUPRO 75262493 is a DNMG-style carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured under the CI series with grade ATP15M, this insert features an uncoated carbide substrate optimized for high wear-resistance across steel, stainless steel, and cast iron workpiece materials. The insert carries an ANSI code of DNMG110404 and an ISO code of DNMG331. With a 55-degree diamond (rhombic) shape, negative side clearance, and a neutral hand orientation, it is suited for general-purpose external and internal turning operations where consistent edge life and dimensional accuracy are critical.

This insert is commonly used in production turning environments including job shops, aerospace component machining, and general manufacturing. It is appropriate for roughing to semi-finishing passes on steel (P), stainless steel (M), and cast iron (K) workpiece materials. The EN-JF chip breaker geometry supports controlled chip formation across moderate to high wear-resistance applications. Machinists and CNC operators working with clamping, lever lock, pin, or screw-style toolholders will find this insert compatible with standard DNMG insert seats.

Key Features

• ANSI Insert Code DNMG110404 and ISO Insert Code DNMG331 for universal toolholder compatibility
• Carbide substrate with ATP15M grade rated for high wear-resistance in steel, stainless steel, and cast iron
• 55-degree diamond insert shape with 4 usable cutting edges for extended tool life per insert
• Corner radius of 0.40 mm (0.0157 inches) for controlled surface finish at moderate feed rates
• Negative side clearance and M tolerance code for rigid, repeatable seating in compatible toolholders
• EN-JF chip breaker geometry for effective chip control across a range of depths of cut

Compatibility

Designed as a standard DNMG-style replacement turning insert for use in toolholders accepting DNMG110404 inserts with clamp, lever lock, pin, or screw holding methods.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Disengage spindle power and confirm the machine is in a safe, locked-out state before changing inserts. Ensure the insert pocket and clamping surfaces are free of chips and debris before seating the insert. Follow the toolholder manufacturer torque specifications for the locking screw or clamp to avoid insert movement or breakage during cutting.
