SCMT120404-FP4 WPP20G turning insert for steel – Tiger·tec Gold, FP4 | Walter Tools

SCMT120404-FP4 WPP20G is a square 90° indexable turning insert designed for productive steel machining with a coated carbide grade and an optimised FP4 chipbreaker

• Tiger·tec Gold coated grade WPP20G
• Optimised FP4 chipbreaker
• 7° clearance for reliable cutting
• Square 90° insert, 0.4 mm corner radius

Stable chip control for higher throughput

The combination of the Tiger·tec Gold coated carbide grade and the FP4 chipbreaker delivers consistently controlled chip formation when machining steels classified under ISO P. The coating improves wear resistance, while the chipbreaker geometry guides chips away from the cutting zone to reduce interruptions. This results in steadier cutting forces and less downtime for chip clearing, which supports increased cycle times and improved process reliability in production turning operations.

Geometry that protects the edge and improves finish

A 7° clearance angle and a 0.4 mm corner radius balance cutting strength with surface quality: the clearance reduces rubbing on the flank face, while the corner radius provides a stronger cutting edge than an acute point, lowering the risk of edge chipping. As a consequence, dimensional repeatability improves and the need for rework is reduced. The insert’s geometry therefore supports both roughing and finishing passes when the process parameters are adapted accordingly.

Standardised format for simple tool management

Following the SCMT designation, the insert is supplied in a common square 90° format with a nominal size of 12 mm and a thickness corresponding to the 04 series. The standardised form factor simplifies toolholder selection and inventory management across workshops that already use SCMT inserts. Tolerance class M ensures consistent fit and orientation in compatible toolholders, helping to maintain predictable cut engagement and repeatable set-ups.

Optimised for steel applications with practical benefits

The WPP20G grade is tuned for machining steel and provides a balance of toughness and wear resistance appropriate for a wide range of steel types. The insert’s coated carbide construction and profile make it a practical choice for customers seeking stable performance in general-purpose turning where process security and consistent surface quality are required. For bespoke parameter recommendations or material-specific guidance, Metav Werkzeuge’s consultants can provide machining data and application advice to support integration into existing production routines.
