Increased productivity, reduced costs

Picks are a vital ingredient of the WIRTGEN cutting technology. They remove the pavement in the milling process, granulating it into small-sized, reusable material. The different operating conditions and types of stress encountered on construction sites both require and promote the development and ongoing refinement of the picks.

Das Design der Rundschaftmeißel variiert zwischen den unterschiedlichen Typen abhängig vom Einsatzgebiet bzw. vom Anwendungsbereich. Die Komponenten und ihre Funktion sind jedoch immer identisch.

Cutting tools for milling machines

The GENERATION X² picks excel due to unique product features, which, above all, reduce operating costs significantly. Thanks to the newly developed wear plate with a special groove profile, centring is improved and rotation performance demonstrably optimised. This ensures that the carbide retains its high cutting performance and guarantees optimum carbide utilisation. The groove profile also reduces lengthwise wear in the pick toolholder and increases service life by up to 25 %.

Highlights of GENERATION X² picks

GENERATION X²: Carbide is the most economical solution as a cutting material for inhomogeneous materials being milled with abrupt peak loads to be expected. The all-round GENERATION X² carbide picks thus provide the optimum solution for every application, no matter whether you need to handle hard or soft asphalt or are milling concrete.

Impressive

- Increased service life for upper part of the toolholders by up to 25 % due to the unique groove profile on the wear plate lower surface of the GENERATION X² picks

- Enormous versatility in the well-conceived GENERATION X² pick product range for a whole variety of construction-site-specific requirements

- High operational reliability for the newly conceived, adapted carbide tip geometry to absorb maximum loads and minimise risk of carbide breakage

PKD cutting tools

Specialist in surface course rehabilitation and (micro) fine milling

PCD milling tools are perfectly suitable for surface course rehabilitations and (micro) fine milling applications due to their tool geometry and materials. They feature a highly wear-resistant tool tip made of polycrystalline diamond (PCD) with an extremely long service life. The very slight lengthwise wear ensures optimum evenness over the milled surface and consistently high machine feed.

Depending on their application, PCD milling tools are a useful addition to the existing pick range featuring conventional carbide tips.

Highlights of PCD cutting tool

PCD milling tools: Polycrystalline diamond (PCD) is the optimal solution as a cutting material for homogeneous asphalt packages, particularly where no abrupt peak loads are expected. PCD milling tools are particularly ideal as an economical alternative for surface course rehabilitations up to 8 cm and for (micro) fine milling applications.

Impressive

- Constant milling pattern due to significantly reduced lengthwise wear

- Increased machine productivity thanks to fewer or no tool replacements and a consistently high machine feed

- Lower operating costs thanks to lower maintenance requirements

Cutting tools for cold recyclers and soil stabilizers

All-rounder for cold recycling and soil stabilization

GENERATION Z picks excel due to unique product features, which, most importantly, reduce operating costs. Thanks to their adapted shank design and optimized carbide tip geometry with a reinforced carbide base, the picks in this product line are designed to withstand high impact loads and are thus the ideal solution for recycling and stabilizing applications.

The relatively large steel body volume compared to conventional picks and the reinforced wear plate deliver the longest possible service life for tools and optimum protection for the upper part of the toolholders in applications involving abrasive materials.

Highlights of GENERATION Z picks

The carbide mix with a high cobalt content of 7% and the reinforced carbide base deliver high stability in the carbide, even under extremely high impact loads. The GENERATION Z all-rounders thus offer the optimal solution for all cold recycling and soil stabilizing applications.

Optimized carbide mix dimensionally correct for applications where high impact loads are expected.

Impressive

- High operational reliability thanks to exceptional impact stress resistance

- Greater productivity, particularly when mixing abrasive materials

- Maximum machine advance rate thanks to flow-optimized pick geometry

WCC milling tools

Specialist in stony ground

WCC (WIRTGEN COMPACT CARBIDE) milling tools are eminently suitable for mixing compact soils with large pieces of rock thanks to their tool geometry and materials. They feature a highly wear-resistant carbide cutting edge, which is extremely fracture-resistant and impact-proof.

Depending on their use, WCC milling tools make a useful addition to the existing pick range with conventional carbide tips.

- Maximum machine productivity thanks to fewer or no tool exchanges

- Low operating costs thanks to lower maintenance requirements

- Maximum impact stress resistance even for large pieces of rock

Picks for Surface Miners

Hard-wearing picks for tough applications

Selecting the right pick is of vital importance both for high cutting performance and for the service life of the pick itself. The pick head diameter, pick head length, carbide diameter and additional armouring are selected individually, based on the material properties and rock hardness, in close cooperation between the customer and WIRTGEN experts.

Different carbide geometries are also used in surface mining due to different fields of application and materials to be cut. Mushroom-shaped carbide tips protect the steel body against erosion; cylindrical carbide tips are used in hard materials.

Picks with 42-mm shank diameter are usually fitted with short clamping sleeves and are used in HT14 and HT15 toolholder systems. These tools are installed in the holder using a copper hammer. Clamping sleeves ensure a rapid, easy change of cutting tools.
