Frequently Asked Questions
The KF HR® is a circular saw blade designed for high-speed friction (hot/parting) cutting of carbon-steel tubes and profiles. It is used on tube and profile production lines, on both stationary and flying (mitlaufende) cut-off machines.
The KF HR® is produced with a patented thermochemical process (Pat. EP1595000) and offers up to 300% longer tool life than standard blades — meaning fewer blade changes and a lower cost per cut.
The KF HR® suits carbon-steel tubes and profiles (e.g. St37, St52; 300–600 N/mm²). We select the right diameter, thickness and tooth count together, based on your section size and line speed.
