CCMT120404-E47 WPP20S — Drilling / bore indexable insert, Tiger·tec Silver, Walter Tools

The CCMT120404-E47 WPP20S is a rhombic 80° indexable insert designed for drilling and bore-enlargement tasks in steel where stable chip formation and repeatable edge life are required

• Tiger·tec Silver coated carbide WPP20S
• Rhombic 80° geometry for stable seating
• 7° clearance angle for controlled cutting
• 0.4 mm corner radius for robust edges

Consistent chip control for steel machining

The coated carbide grade provides reliable chip control in steel applications, reducing rework and improving process stability. The insert’s E47 chipbreaker has been tuned for the heat and chip forms typical when machining unalloyed and alloyed steel, so metal removal is more predictable and swarf management is improved. This results in fewer interruptions to production and a steadier surface finish, which translates directly into higher throughput and less post-process cleaning.

Robust edge life through optimized geometry and grade

The rhombic 80° form combined with a 0.4 mm corner radius offers mechanical strength at the cutting edge, increasing resistance to edge chipping under interrupted cuts common in drilling and bore enlargement. The WPP20S grade, part of the Tiger·tec Silver family, uses a coated hardmetal substrate designed for a balance of wear resistance and toughness. Consequently, the insert sustains longer service intervals and supports consistent dimensional accuracy over repeated tool changes.

Practical integration and productivity gains on the shop floor

Featuring a 7° clearance angle, the insert reduces rubbing and heat build-up at the flank, which lowers cutting forces and helps maintain toolholder stability. The industry-standard CCMT geometry enables straightforward integration into existing toolholder systems for drilling and boring, simplifying inventory and changeover. Where process reliability and predictable tool behaviour are priorities, this insert offers an efficient route to reduced downtime and more consistent component quality.

FAQ

What types of steel is this insert suitable for?
This insert, CCMT120404-E47 WPP20S, is formulated for the P group (steel), covering typical unalloyed and alloyed steels where stable chip formation is required.

How does the Tiger·tec Silver coating benefit performance?
The Tiger·tec Silver coating on the WPP20S grade improves wear resistance and heat protection, extending edge life and supporting consistent removal rates during drilling and bore enlargement.

Is this insert compatible with standard CCMT toolholders?
Yes, the CCMT geometry conforms to industry standards, allowing the insert to be used in compatible CCMT toolholders for drilling and reaming operations.

What machining advantages does the E47 chipbreaker provide?
The E47 chipbreaker is optimised for the chip shapes encountered in steel machining, promoting controlled swarf evacuation and reducing the chance of built-up edge formation.

Can the insert handle interrupted cuts?
The rhombic 80° geometry and 0.4 mm corner radius give the insert enhanced mechanical strength, which improves resistance to chipping during interrupted operations.
