»King Grit« and »King Shield« - wear protection technology by King Kong Tools

Gain the utmost in productivity and output from your forestry mulcher, wood grinder, rock crusher and tunnelling head: with »King Grit« and »King Shield« wear protection.

King Grit

The King Grit technology is based on the MIG (metal inert gas) welding process where an electric arc burns between the melting and the welding rod in an inert gas atmosphere at extremely high temperatures. Computer-controlled feeding of carbide chips into the welding zone creates a coarse grained surface with carbide chips equally distributed throughout the King Grit layer.

Tools protected with King Grit show very high wear resistance, extreme impact tolerance and unmatched cutting ability and are used in the most severe cutting conditions.

King Shield

In certain applications, cutting ability is not what you are looking for. For example, round shank bits working in abrasive rock experience enormous wear along the steel body of their cutting heads. King Shield perfectly protects the carbide tip from being washed out.

Here, the MIG electrode consists of a special alloy with microscopic WC (tungsten carbide) particles imbedded. The extreme temperatures create a plasma welding layer with a smooth and extremely hard surface. It resists the enormous abrasiveness of quartz containing minerals while showing a high tolerance against impact loads.

PLA welding technology

Another technology used by KingKong-Tools to protect tools from wearing is the PLA technique, also known as plasma laser overlay welding.

In plasma laser overlay welding, a laser is used to create a liquid weld pool on the tool surface. A defined amount of metal powder is introduced into this weld pool through a nozzle, resulting in welded beads that can produce almost any desired shape. Due to this flexibility in applying the wear protection, cutting edges and steel bodies of our tools are optimally and effectively protected against wear.

With our 3D laser, we use a special manufacturing process that enables us to create metallic material applications on existing tools as if from a single cast. And that without any loss of quality, tight and crack-free. As a result, laser overlay welding offers excellent wear protection while at the same time retaining the aggressive cutting action of our blade tools.

We also offer individual hard facing designs. Call us if you have any questions about our King Grit and King Shield wear protection. Surely we can come up with a tailor-made solution for your application!
