PICKS WITH 38 / 30-STEPPED SHANK

They are used in HT6 toolholder systems. These tools are the established solution and are secured using a simple locking ring.

PICKS WITH 42-MM SHANK DIAMETER

They 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.

This is a great advantage with hard materials which cause heavy, rapid wear on carbide and steel body as the clamping sleeve is designed for a short to medium pick service life.

If a longer service life is expected, an optional c-clip (not included in delivery) can ensure that the cutting tool’s maximum life span is achieved. The pick head diameter and geometry have been selected in such a way that greater protection is assured for toolholders.

Depending on the specific use, additional tools with different types of head armouring can also maximise service life. The picks WSM2-17-90 /42 with mushroom-shaped tips are used in Russia due to the fluctuating characteristic of lime stone from hard to soft. The head length of the tool is 90 mm

Due to the material properties of the coal ore, picks WSM3-24-77/ 38 / 30 with capshaped carbide tips are used in India. This pick is installed in milling drums with HT6 (stepped shank 38 / 30 mm) and fixed using a retaining ring.

The above-mentioned applications and the materials to be cut show that different carbide geometries are also used in surface mining. Cap-shaped carbide tips (“WSM3”) protect the steel body against erosion, cylindrical carbide tips (“WSM1”) are used in hard materials. The mushroom-shaped tip (“WSM2”), in simple terms, combines both properties, advantages and disadvantages
