20 x 12mm Parting Tool Carbide P25/P30 5mm Cut Width, DIN 4981 (ISO 7) - Werner Wilke Zerspanungstechnik GmbH

Take advantage of the combination of carbide P25/P30 durability, a 5 mm parting width and a rigid 20 x 12 mm shank for controlled, repeatable parting operations; order directly via Metav Werkzeuge or ask the technical consultants for application advice.

Wilke Stechdrehmeißel (Parting Tool) 20 x 12 mm — HM P25/P30, left-hand

The Stechdrehmeißel (parting tool) is designed for left-hand parting and grooving in lathe turning, featuring a robust 20 x 12 mm shank and diamond-ground carbide cutting plates for stable performance.

• Carbide grades P25/P30 for durability
• 5 mm parting width for precise cuts
• 20 x 12 mm shank, 125 mm overall length
• Left-hand cutting, DIN 4981 (ISO 7) compatibility

Durable carbide for consistent cutting performance

The tool uses Hartmetall P25/P30 inserts that combine wear resistance with a balanced toughness, reducing the frequency of insert changes and downtime. Diamond-ground cutting faces ensure a consistent cutting edge geometry, which improves surface finish and reduces micro-chipping during high-precision parting work. This results in fewer interruptions to the machining cycle and a measurable uplift in process stability when compared with generic-grade inserts.

Compact, rigid design for accurate parting and groove control

A 20 x 12 mm shank cross-section and an overall length of 125 mm provide the rigidity required for narrow 5 mm parting operations. The compact profile reduces deflection under load and supports accurate depth control, so operators benefit from cleaner cut-off points and reduced secondary finishing. Conformance to DIN 4981 (ISO 7) simplifies integration with compatible tool holders, ensuring straightforward mounting and repeatable set-up.

Left-hand orientation and standard compatibility for flexible shop use

The left-hand cutting orientation is suited to applications where tool approach and spindle rotation necessitate a leftward cutting direction; this is specified in the product designation to avoid setup errors. The parting blade is equipped on a steel shank with diamond-ground carbide plates, a configuration that balances economy with service life. For shops standardising tooling, the compliance with recognised norms streamlines inventory choices and reduces the need for bespoke holders.

Practical handling and predictable maintenance

Thanks to the replaceable carbide plates, maintenance focuses on quick insert swaps rather than full tool replacement, cutting service time and inventory waste. The tool’s geometry supports controlled chip formation at the specified 5 mm cutting width, reducing the chance of chip entanglement during parting. For complex or critical applications, Metav’s technical team can provide guidance on optimised cutting parameters and compatible tool holders to preserve tool life and part quality.

FAQ

What does left-hand cutting mean for setup?
Left-hand cutting indicates the tool is designed to cut when fed from right to left relative to the workpiece; the Wilke parting tool must be mounted accordingly to match spindle rotation and feed direction.

How wide is the cutting slot produced by this tool?
The tool provides a 5 mm parting width as specified; this dimension refers to the effective cut width produced by the carbide cutting plates.

Which standard ensures holder compatibility?
Compatibility is assured by DIN 4981 (ISO 7), which defines the tool-shank and holder interfaces relevant to this parting tool.

What are the benefits of P25/P30 carbide grades?
P25/P30 carbide grades offer a balance of wear resistance and toughness, delivering reliable edge life for interrupted cuts and the demands of parting operations.

How is the tool maintained when inserts wear?
The diamond-ground carbide plates are replaceable; worn plates are exchanged rather than replacing the entire shank, reducing maintenance time and material waste.
