CCMT09T308-E47 WPP20S drilling/boring indexable insert by Walter Tools — Tiger·tec Silver, rhombic 80°

CCMT09T308-E47 WPP20S offers a versatile insert for drilling and bore-enlarging applications in steel, combining coated carbide grade performance with a proven CCMT geometry for secure clamping and predictable cutting behaviour

• Tiger·tec Silver coating for durability
• Grade WPP20S tuned for steel machining
• Rhombic 80° geometry for versatile clamping
• 0.8 mm corner radius for stable cutting

High-performance grade engineered for steel productivity

The WPP20S grade, part of the Tiger·tec Silver family, is a coated carbide formulation optimised for machining steel. Its microstructure and coating balance wear resistance and toughness so that the insert handles the typical heat and chip form of steel cutting. This results in longer tool life and fewer insert changes, which improves throughput and reduces unplanned downtime. The grade is categorised as universally applicable within steel machining, giving dependable performance across a range of cutting conditions.

Geometry and edge preparation that stabilise cutting results

The rhombic 80° form with the CCMT-style pocket designation provides secure seating and repeatable orientation in standard toolholders. The 0.8 mm corner radius reduces edge chipping risk while offering a compromise between edge strength and finishing capability. Combined with a modest 7° relief angle, this geometry supports stable cutting forces during drilling or bore enlargement, improving dimensional consistency and reducing the risk of vibration-related marks on workpieces.

Coating technology that extends service intervals

The Tiger·tec Silver coating is engineered to improve thermal stability and adhesion on the carbide substrate. This layered surface helps resist abrasive wear and built-up edge formation under the thermal loads typical of steel machining. Fewer interruptions for insert changeover translate into higher effective machine utilisation and an improved cost-per-component metric. The coating also contributes to consistent surface quality over longer tool life, supporting production runs where repeatable finish is required.

Chip control and operational advantages for shop-floor efficiency

The integrated E47 chipbreaker is designed to manage chip formation during drilling and reaming operations, promoting short, controllable swarf that evacuates reliably from the bore. Better chip control reduces the likelihood of recutting chips or tool breakage and facilitates safer high-feed cycles. Together with the coated grade and robust geometry, the insert supports efficient, predictable machining cycles that aid process planning and reduce the need for corrective rework.

FAQ

What materials is this insert intended for?
The CCMT09T308-E47 WPP20S insert is optimised for machining steel and is specified for the P material class according to ISO recommendations.

How does the Tiger·tec Silver coating benefit production runs?
The Tiger·tec Silver coating on the WPP20S grade improves wear resistance and thermal stability, which extends insert life and supports consistent surface quality during longer production runs.

Can the insert be used in standard CCMT toolholders?
Yes, the CCMT09T308-E47 form follows CCMT geometry and is compatible with standard CCMT-compatible toolholders designed for rhombic 80° inserts.

What role does the E47 chipbreaker play?
The E47 chipbreaker shapes chip flow for controlled, short chips during drilling and bore enlargement, improving evacuation and reducing recutting risks.

Is the insert suitable for finishing or roughing operations?
With a 0.8 mm corner radius and coated carbide grade, the insert provides a balance between edge strength and surface finish; it performs well in medium to finishing cuts where stability and repeatable results are required.
