SCMT09T308-E47 WPP20S square boring/reaming indexable insert, Tiger·tec Silver coating, for steel – Walter Tools

The SCMT09T308-E47 WPP20S is a square 90° indexable insert designed for efficient boring and reaming of steel components in production environments

• Tiger·tec Silver coated for durability
• Optimised for steel machining
• 7° relief angle for stable cutting
• 0.8 mm corner radius for robustness

Reliable cutting performance for demanding steel work

The combination of the WPP20S grade and a coated carbide substrate gives a clear advantage when working with steel: high abrasion resistance and predictable wear behaviour. Thanks to the Tiger·tec Silver technology, the insert sustains longer cutting edge life under typical steel cutting temperatures, which reduces the frequency of tool changes and minimises unplanned downtime. This results in more stable cycle times and contributes to improved process efficiency on medium- to high-volume production runs.

Longer tool life through advanced coating and geometry

The Tiger·tec Silver coating, paired with a deliberately chosen 0.8 mm corner radius and a 7° relief, emphasises a balance between edge strength and cutting efficiency. The coated surface reduces adhesive wear and improves thermal resistance, while the moderate corner radius protects the edge from chipping during interrupted cuts. These design choices mean fewer regrinds and a higher yield per insert, supporting cost-effective machining without compromising surface finish expectations.

Stable chip control and repeatable accuracy for boring operations

A square 90° plate form with chipbreaker E47 and size 09 provides consistent chip formation and evacuation in typical steel turning and boring tasks. The tolerance class M and plate thickness T3 ensure reproducible clamping and positioning in standard tool holders, which helps to maintain workpiece accuracy across multiple tool changes. By combining stable geometry with a reliable chip control design, the insert supports higher metal-removal rates while preserving dimensional stability in serial production.

FAQ

Is this insert suitable for machining steel?
Yes. The insert grade WPP20S is designed specifically for steel (P) and offers the wear properties and chip control needed for reliable steel machining.

What coating and substrate does the insert have?
The insert uses Tiger·tec Silver coating on a coated carbide substrate, which improves thermal resistance and wear behaviour for demanding operations.

What are the key geometry specifications of the insert?
The plate is a square 90° form with a 0.8 mm corner radius and a 7° relief angle, suitable for stable boring and reaming applications; chip control is provided by the E47 breaker.

Which tool designation should be ordered for this insert?
Order using the designation SCMT09T308-E47 WPP20S (SKU: SCMT09T308-E47-WPP20S-WALTER) to ensure the correct grade and geometry are supplied.

Is the insert designed for interrupted cuts or continuous finishing?
The geometry, including the corner radius and relief, provides a compromise between edge strength and finishing capability, making it suitable for a range of steel machining tasks where stability and consistent surface quality are required.
