Cutting Materials

Added value with SPK cutting materials.

Due to unbeatable wear resistance hardness and hot hardness SPK-Ceramics established itself as an ideal cutting material for mass production of cast iron parts, hard rolls and hardened steel. Machining speed is increased, production time shortened, output, productivity and efficiency are highly improved.

A wide range of products for SPK-WURBON® is completing the range of cutting materials for high performance machining of cast iron and hardened steel.

SPK-Cermets achieve best surface qualities and dimensional accuracy of the work pieces in finishing steel. They are ideal suited for finishing and fine finishing operations with low chip cross sections and uniform depths of cut.

SPK cutting materials for boring

SL 508
This new silicon nitride is ideal suited for high-performance rough milling of cast iron. The outstanding wear resistance in combination with excellent toughness promise good process reliability under the roughest conditions.

SL 506
Special grade for finish turning operations on grey cast iron materials. The grade incorporates mechanically resistant materials which enable an enormous improvement of the grade’s edge stability and wear resistance without affecting its toughness.

SL 500
Universal silicon nitride grade particularly suited for roughing and finishing of grey cast iron materials performed with both continuous and interrupted cuts.

SL 554 C
The gold colored TiCN-TiN multilayer coating increases wear resistance while reducing the frictional forces between insert and workpiece. It is especially suited for rough turning of high-strength nodular cast iron with both continuous and highly intermittent cutting.

SL 550 C
This silicon nitride grade comes with a TiN-Al2O3 coating which enables roughing and semifinishing operations on nodular graphite cast iron even under severe cutting conditions.

WBN 100
Poly crystalline boron nitride for milling of chilled cast iron, hardened cast iron, sintered metals and hard coatings.

WBN 101
is a solid WBN grade, and owing to its optimized toughness and wear resistance is particularly suited for machining rolls made of chilled cast iron.
