CNMG120412-MP3 CNMG120412-MP3 WPP30G — turning insert for Stahl machining, Walter Tools

The CNMG120412-MP3 WPP30G is a rhombic 80° turning insert designed for general Stahl turning, combining a robust WPP30G coated carbide grade with a proven chip control geometry for reliable production results.

• Tiger·tec Gold coating for high productivity
• WPP30G coated carbide for Stahl machining
• Rhombic 80° shape with 1.2 mm corner radius
• MP3 chipbreaker for reliable chip control

Increased productivity through coating and grade

The Tiger·tec Gold combination and WPP30G grade deliver measurable gains where heat and wear are critical. The coated carbide substrate with modern multilayer technology reduces flank and crater wear, extending tool life under continuous operation. This results in fewer indexings and lower tool-change frequency, which directly contributes to higher throughput and improved machine utilisation. The design suits serial turning tasks where process stability is essential.

Predictable machining on Stahl with controlled chip flow

Rhombic 80° geometry and the MP3 chipbreaker produce short, controllable chips in a wide range of cutting parameters. The insert’s 0° negative rake promotes secure cutting under interrupted cuts and facing operations, while the 1.2 mm corner radius helps to balance edge strength and surface quality. The P-class assignment according to ISO indicates suitability for unalloyed and alloyed Stahl, making this indexable insert a versatile choice for general turning operations where consistent surface finish and repeatability are required.

Economical handling and process reliability

The CNMG form provides four usable cutting edges per indexable insert, lowering cost per edge and simplifying inventory management. Tolerance class M ensures repeatable seating and accurate clamping in compatible toolholders, supporting predictable cycle times. The platelet thickness and form match standard toolholders for CNMG inserts, easing retrofit into existing tool families. For application advice or cutting data tailored to a specific machine or batch, technical consultations are available to assist process optimisation.

FAQ

Which materials is this insert suitable for?
The CNMG120412-MP3 WPP30G is specified for Stahl machining and was developed to manage the heat and chip formation typical of this material group.

What benefit does the MP3 chipbreaker provide?
The MP3 chipbreaker creates short, controllable chips, improving shop-floor safety and enabling more reliable unattended cycles with the CNMG insert.

How does Tiger·tec Gold improve performance?
Tiger·tec Gold coating enhances wear resistance and heat management, which extends edge life and maintains consistent cutting behaviour during longer production runs.

Is the negative rake angle advantageous for interrupted cuts?
Yes; the 0° negative rake increases edge strength, making the insert more tolerant to interruptions and heavy cuts without premature chipping.
