Value Collection K15ER-B12-4-0C8 Turning Insert C8

Product Description

The VALUE COLLECTION K15ER-B12-4-0C8 is a carbide turning insert designed for metal cutting operations on CNC and manual lathes. It carries a C8 manufacturer grade with a TiN coating applied via PVD process, giving it wear resistance suited for medium machining conditions. The insert features a right-hand orientation, positive rake angle of 12 degrees, and negative side clearance. With 2 cutting edges and a maximum depth of cut of 4.00 mm, it is built for back turning applications across a range of ferrous workpiece materials. Screwlock holding secures the insert firmly in compatible toolholders during operation.

This insert is intended for use on steel, stainless steel, and cast iron workpieces, covering ISO material codes P, M, and K. It falls under the K15ER series and conforms to both ANSI and ISO standards. Material grades supported include K05, K20, M05, M20, P05, and P10, making it adaptable across light to moderate cutting passes on ferrous alloys. It is suited for production turning environments where consistent chip control and surface finish are required in medium machining duty.

Key Features

• C8 grade carbide insert with TiN PVD coating for wear resistance in medium machining
• Positive rake angle of 12 degrees reduces cutting forces on ferrous materials
• Right-hand orientation with negative side clearance for back turning applications
• Maximum depth of cut of 4.00 mm supports moderate material removal rates
• 2 cutting edges extend usable tool life per insert
• Screw holding method provides secure, repeatable seating in compatible toolholders

Compatibility

Designed for use with K15ER-series toolholders accepting B12 insert style. Compatible workpiece materials include steel, stainless steel, and cast iron corresponding to ISO material grades P05, P10, M05, M20, K05, and K20. Conforms to ANSI and ISO insert standards.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct screw torque driver for the toolholder manufacturer's specified fastener to avoid cracking the carbide. Inspect the insert pocket for debris or wear before seating a new edge.
