SCMT120408-E47 WPP20G Bohr-/Aufbohrwendeschneidplatte, Tiger·tec Gold for steel by Walter Tools

The SCMT120408-E47 WPP20G is a square 90° indexable insert engineered for drilling and reaming in steel, offering high wear resistance and stable chip control for reliable production runs

• Tiger·tec Gold coating for long tool life
• Square 90° form for stable cutting
• 7° clearance angle for smooth chip flow
• Optimised E47 chipbreaker for steel

Boost throughput with predictable tool life

The combination of Tiger·tec Gold surface technology and a coated carbide substrate delivers measurable gains in cycle time and insert longevity when machining steel. The specialised coating reduces flank wear and maintains edge integrity under the thermal and mechanical loads typical of drilling operations. With an E47 chipbreaker designed specifically for continuous chip control in ferrous materials, tool changes become less frequent, which reduces unplanned downtime and increases effective machine availability. For process planners, the result is a more economical machining step that pays back through lowered tooling consumption and fewer interruptions.

Secure hole quality and repeatable results

A square 90° geometry and a 0.8 mm corner radius provide a rigid cutting edge and predictable engagement in the hole wall, improving axial stability and surface finish. The 7° clearance angle supports efficient chip evacuation while limiting rubbing on the flank, which helps keep hole tolerances stable across batch production. These geometric choices reduce vibration and support consistent dimensional results, making the insert suitable for operations where repeatability and hole integrity are critical, such as jig drilling or preparatory reaming before finishing passes.

Practical integration for workshop efficiency

Indexable format simplifies inventory and handling compared with solid drills: a small number of inserts can serve many bores before full tool replacement is required, which simplifies stockkeeping and reduces preparation time. The insert series is compatible with common Walter toolholder systems and is supplied under the Tiger·tec Gold family for straightforward sort selection. When integrating into a new toolset, specify the toolholder interface and the required insert designation to ensure correct seat and clamping. If process parameters or holder choices are unclear, Metav Werkzeuge’s technical team can advise on cutting data and holder matches to optimise results with this insert.

FAQ

What materials is this insert suitable for?
The SCMT120408-E47 WPP20G is intended primarily for steel (designation P) and is engineered to manage the heat and chip formation typical of ferrous machining.

How does the Tiger·tec Gold coating affect performance?
The Tiger·tec Gold coating on the SCMT120408-E47 WPP20G improves wear resistance and edge stability, extending productive cutting life and reducing frequency of insert changes.

Which chipbreaker is fitted and why does it matter?
The insert uses an E47 chipbreaker, optimised for reliable chip control in steel, which reduces clogging and aids consistent evacuation during drilling and reaming.

Can this insert be used with standard Walter holders?
Yes, the insert designation SCMT120408-E47 fits common Walter toolholder families; confirm holder seat type and clamping for a secure fit.

What geometric features improve hole quality?
The square 90° form combined with a 0.8 mm corner radius and a 7° clearance angle enhances axial stability and supports repeatable hole tolerances.
