CCMT060202-E47 WPP20G drilling/reaming indexable insert for steel — Walter Tools

CCMT060202-E47 WPP20G is a drilling and bore‑enlarging indexable insert designed for efficient holemaking in a wide range of steels

• Tiger‑tec Gold coating for long life
• Optimised for steel ISO P applications
• 80° rhombic shape for flexible indexing
• 0.2 mm corner radius for precise cutting

Optimised coating and grade for reliable productivity

The combination of the Tiger‑tec Gold technology and the WPP20G grade creates a balanced, coated‑carbide solution tailored to the thermal loads and chip forms typical of steel machining. This coating strategy enhances wear resistance, reduces flank wear progression and ensures a predictable tool life. The integrated chipbreaker E47 supports continuous chip control during hole enlargement, reducing the risk of clogging and enabling stable feeds and spindle speeds. For production environments seeking repeatable cycle times, these properties translate directly into lower tooling costs per part and fewer unscheduled tool changes.

Geometry that improves hole quality and process stability

The 80° rhombic plate form and a 0.2 mm corner radius provide a geometry that resists edge chipping while delivering a consistent cutting line on bore walls. The 7° clearance angle reduces rubbing and heat at the cutting edge, improving surface finish and dimensional consistency in consecutive holes. These features support both semi‑finishing and finishing passes, where geometric stability is essential to meet tolerance and roundness requirements. Explained simply: smaller corner radii give sharper engagement for accuracy, while the rhombic shape allows multiple effective index positions to extend insert life.

Predictable integration into existing tool systems

With a standard designation of CCMT060202‑E47, this insert matches common mounting and clamping systems used in drilling and reaming toolholders. The tolerance class M ensures consistent interchangeability between inserts, reducing setup time and minimising the need for special adjustments. As a coated cemented‑carbide grade, it fits routine workshop processes without requiring unusual coolant strategies; conventional flood or through‑tool coolant practices remain effective. The net effect is straightforward: faster tool changes, stable process parameters and improved overall equipment effectiveness.

Broad suitability for steel applications and recommended uses

The material code indicates primary suitability for steel (ISO group P). The WPP20G grade is positioned as a universal solution that balances resistance to abrasive wear with adequate toughness for a range of steel grades, from softer low‑alloy steels to tougher, more work‑hardening materials. Use this insert for hole enlargement, spot boring and other holemaking operations where a combination of chip control and edge stability matters. When selecting feeds and speeds, prioritise consistent chip evacuation and modest depth per pass to exploit the insert’s balanced performance.

FAQ

Is this insert suitable for all steel grades?
The CCMT060202‑E47 WPP20G insert is formulated for steel (ISO P) and offers a universal balance of wear resistance and toughness, making it suitable for a wide range of common steel grades.

How does the Tiger‑tec Gold series affect tool life?
The Tiger‑tec Gold coating enhances wear resistance and thermal stability on the cutting edge, which extends the service life of the insert under typical steel machining conditions.

Can the insert be indexed multiple times for extended life?
Yes, the 80° rhombic shape provides several index positions, allowing repeated use of fresh cutting edges and improving overall productivity.

What does the chipbreaker E47 provide in holemaking?
The E47 chipbreaker is designed to promote stable chip formation and evacuation during bore enlargement, reducing the risk of clogging and improving surface finish in the hole.

Does tolerance class M impact interchangeability?
Tolerance class M indicates a medium tolerance level that supports consistent fit and interchangeability across standard toolholders without custom adaptation.
