spherical head grinder

The anti-swivel coupling continues to be a premium solution when it comes to the safety of trailer coupling. To make sure it can perform as expected, the spherical head must be free from any paint, rust or rust bloom.With the new spherical head grinder - specially designed for non-swinging coupling - you can be on the safe side.In 10 - 15 seconds it will be completely clear. And you can be sure to arrive safely at your destination. 

It is essential to have a completely paint-free, rust-free, clean spherical head in the non-swing coupling if it is to function perfectly. It must have a bare metallic surface that is free from any grease. There are no exceptions. Removing paint and rust, and cleaning is obligatory before putting it into operation. The manufacturers require this. Otherwise there is a danger that friction materials clog the non-swing coupling with paint and dirt particles and this could inhibit 100% functionality.

You can tell this has happened if there are loud creaking noises from the trailer coupling during shunting operations or when going around corners, or perhaps not until a hazardous situation is encountered - for instance, when an accident is unavoidable.
The Kruse Tech spherical head grinder is used in conjunction with a standard cordless screwdriver directly on the spherical head in the trailer coupling. Even at a low speed and after a few rotations, the desired result can be quickly achieved - and the safe function of the non-swing coupling is assured.

There is absolutely no need for laborious manual cleaning of the spherical head. No sanding, no industrial cleaners, no cleaning cloths. From now on, all that can be consigned to history.

Using the Kruse Tech K4708 spherical head grinder and a cordless screwdriver, you can clean successfully in just a few seconds.

When used properly, the grinding material on the spherical head grinder doesn't impact the surface of the ball itself, but thanks to the elasticated design only removes paint, rust and contamination.
