RoTo Kruna Roto Rasp – Fast and Efficient Plastic Grinding
New and innovative tools and equipment that were not originally developed for farriers sometimes find their way into everyday farrier work and prove extremely useful. This is also true of the roto rasp made by RoTo Kruna in Croatia. Originally developed for working with wood and other soft materials, it is ideal for adjusting the plastic shell of our horseshoes.
The roto rasp is a versatile tool for angle grinders and can be an interesting alternative, especially for users who do not have a belt sander. It is also ideal for adding a deeper tread pattern to a horseshoe.
We consider the roto rasp a useful addition to our product range , as it enables efficient and clean plastic processing – both for precisely grinding a deeper tread pattern into the material and for quickly removing excess material.
What Makes the RoTo Kruna Roto Rasp Special
The roto rasp is a versatile cutting tool designed for use with standard angle grinders. It is ideal for working on wood, plastic, rubber, synthetic resin, and other soft materials. This also makes it suitable for working on our composite and urethane horseshoes and accessories.
Thanks to its special cutting-edge geometry, the roto rasp removes significantly more material than conventional sanding discs or sandpaper. At the same time, it is far less likely to clog than traditional grinding discs. This is especially useful when adding a deeper tread pattern afterward.
It also offers a long service life, allowing material to be processed quickly and efficiently while significantly reducing tool wear. This, in turn, helps lower costs.
Applications of the RoTo Kruna Roto Rasp
Suitable for Working on Plastic
The roto rasp is ideal for adjusting the plastic shell of our composite and urtehane horseshoes. It can also be used to work on products made entirely of plastic, such as plastic horseshoes, wedges , Extensions , and similar products.
Not Suitable for Working on Metal
Do not use the roto rasp on metal. When adjusting composite horseshoes, make sure the roto rasp does not come into contact with the metal core. When working on the Arizona in particular, be aware that you may reach the metal sooner in the area of the steel border. Always maintain sufficient distance from quarter clips and other metal components of the horseshoe.
Not Suitable for Hoof Trimming
In our opinion, the roto rasp is not suitable for hoof trimming, primarily because the risk of injury would be too high. For this application, we recommend the proven fiber discs made by Pferd.
