Kennametal 1163532 RCMK23 K313 Carbide Profiling Insert

Product Description

The KENNAMETAL 1163532 is a solid carbide round profiling insert designed for turning and profiling operations on non-ferrous metals, superalloys, and titanium. Manufactured to the RCMK23 standard and carrying the K313 fine-grain carbide grade designation, this insert features an uncoated WC-Co substrate that maintains sharp cutting geometry without the added thermal barrier of a coating. The insert has a 0.25-inch inscribed circle, a thickness of 0.358 inches (9.09 mm), and provides a maximum depth of cut of 0.125 inches. The round shape delivers a full 360-degree included angle, giving machinists four usable cutting edges per insert.

This insert is suited for profiling and finish turning applications in CNC lathes and turning centers where tight contour control is required. The round geometry allows the tool path to follow complex profiles without repositioning the insert, making it a practical choice for aerospace, medical, and general machining work involving difficult-to-cut materials such as titanium alloys and nickel-based superalloys. It is held in place using a combination clamp and pin method within K-Lock compatible toolholders, ensuring secure seating during aggressive cuts.

Key Features

• Round RCMK insert shape with 360-degree included angle and 4 cutting edges per insert
• Fine-grain K313 solid carbide grade optimized for non-ferrous metals, superalloys, and titanium
• Uncoated WC-Co substrate for a sharp, consistent edge without coating buildup
• Positive rake angle of 7 degrees with a 5-degree relief angle for free-cutting action
• 0.125-inch corner radius integral to the round shape for smooth surface finish on contoured profiles
• K-Lock series seating secured by clamp and pin holding method for rigid tool engagement

Compatibility

Designed for use with K-Lock series toolholders accepting RCMK23 or ISO RCMK060400 round inserts. Conforms to RCMK23 and RCMK060400 standards. Verify toolholder pocket specifications before installation.

Installation Notes

Insert installation should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Seat the insert firmly into the K-Lock pocket and secure using both the clamp and locating pin to prevent rotation under cutting load. Do not exceed the rated maximum depth of cut of 0.125 inches for this insert geometry. Inspect the cutting edge and pocket seating surface for chips or debris before each insert change.
