CCMT09T304-E47 WPP20S drilling/boring indexable insert — Tiger·tec Silver, for steel, Walter Tools

CCMT09T304-E47 WPP20S is a drilling/boring indexable insert designed for productive steel machining in demanding turning and bore-finishing operations

• Tiger·tec Silver coating for productive machining
• ISO P compatibility for steel applications
• Rhombic 80° geometry with 7° relief
• E47 chipbreaker for controlled chip formation

Consistent machining quality through coated-carbide grade and geometry

The combination of the WPP20S grade and Tiger·tec Silver coating offers a balanced mix of wear resistance and toughness, optimised for steel (ISO P) machining. This coated carbide formulation is developed to handle the typical heat and chip formation of steel cutting, reducing flank wear and extending edge life. The Rhombic 80° outline provides a versatile effective cutting edge for drilling-related turning and bore operations, while the 0.4 mm corner radius increases edge strength, improving surface finish and part consistency without compromising tool life.

Reliable chip control and process stability for productive cycles

Built around the E47 chipbreaker, the insert controls chip form and evacuation under standard steel cutting conditions, reducing interruptions and keeping cycle times steady. The 7° relief reduces rubbing and cutting forces, helping to maintain thermal stability in the cut. With tolerance class M and a T3 thickness, the insert offers predictable seating and repeatable position accuracy in standard toolholders, supporting unattended or high-volume runs with fewer interruptions and more consistent part quality.

Practical advantages for workshop and production environments

The format and dimensions (insert size 09) make this grade suitable for a wide range of toolholders and applications where steel turning and boring tasks require both productivity and surface integrity. The coated carbide substrate resists built-up edge and improves edge retention, which translates into fewer tool changes and lower machining downtime. By selecting this insert, process planners benefit from a stable, general-purpose solution that balances tool life and productivity for mixed batch production.

Application guidance and selection rationale

For steels and typical carbon and alloy steels (ISO P), the WPP20S grade is recommended where a combination of economical wear resistance and dependable toughness is required. The insert's chip control and geometry suit finishing and medium-turning passes associated with boring and internal profiling. When specifying the cutting data, factor in the corner radius for surface finish targets and choose feeds that avoid excessive edge load to exploit the grade’s wear resistance while preserving cutting-edge integrity.

FAQ

What materials is this insert suitable for?
The CCMT09T304-E47 WPP20S is designed for steel applications (ISO P); the WPP20S grade and Tiger·tec Silver coating are optimised for the heat and chip characteristics of unalloyed and alloyed steels.

How does the E47 chipbreaker affect machining?
The E47 chipbreaker promotes controlled chip formation and evacuation in steel machining, which reduces workpiece damage and machine interruptions during drilling-related turning and boring tasks.

What advantages does the 0.4 mm corner radius offer?
A 0.4 mm corner radius increases edge strength for better surface finish and improved resistance to edge chipping, supporting stable finishing passes without excessive tool wear.

Is this insert suitable for finishing or roughing?
With the coated WPP20S grade and its balanced wear/toughness profile, the insert suits finishing and medium turning; its chip control also supports process stability during light to moderate stock removal.

How precise is the insert seating and repeatability?
The insert is supplied to tolerance class M and a T3 thickness, providing predictable seating and repeatable positioning in standard toolholders for consistent part tolerances.
