Kennametal 1841355 VPGR334 KC5010 Carbide Profiling Insert

Product Description

The KENNAMETAL 1841355 is a VPGR334-style carbide profiling and turning insert manufactured to KC5010 grade with an AlTiN PVD coating. It features a parallelogram shape with a 35-degree included angle, a positive rake geometry at 10 degrees, and an 8-degree relief angle. The inscribed circle measures 3/8 inches (0.3750 inches), thickness is 3/16 inches (0.1875 inches), and the corner radius is 0.0625 inches (1.59 mm). With two cutting edges per insert and a maximum depth of cut of 0.2179 inches, this insert is suited for high-productivity turning and profiling operations. It is installed by machinist technicians and CNC turning operators in production and job-shop environments.

This insert is designed for profiling and turning operations across a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It corresponds to ISO code VCGR160416 and carries material grade designations P10, P20, M10, M20, K05, K10, K15, K20, N10, N20, S10, S20, and H10, making it applicable to a broad spectrum of machining applications in both production turning and contour profiling. It fits the Top Notch series and is held in place with a clamp-style insert holding method.

Key Features

• Parallelogram insert shape (VPGR334) with 35-degree included angle and positive rake geometry
• 0.0625-inch (1.59 mm) corner radius for controlled profiling and contour turning
• Maximum depth of cut of 0.2179 inches for moderate stock removal in turning passes
• Two cutting edges per insert for extended tool life between index events
• Neutral hand orientation and common chipbreaker for versatile setup across turning centers

Compatibility

Conforms to VPGR334 and ISO VCGR160416 standards. Designed for use in Top Notch series clamp-style toolholders that accept VPGR334 inserts. Compatible with turning applications on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials per ISO material groups P, M, K, N, S, and H.

Installation Notes

Installation is performed by qualified machinists or CNC turning technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver for the clamp screw as specified by the toolholder manufacturer — do not overtighten, as this can fracture the insert. Inspect the toolholder seat and clamp for debris or wear before seating the new insert.
