Our best selling Thincut cut-off wheels represent the superior comfort and performance Tyrolit is known for worldwide. Designed and manufactured for fast burr free cutting in steel, stainless steel and aluminum. All 2 in 1 wheels are certified Fe S CI free - No contaminants. Deep cut wheels: The deep cut protection metal bushing we have developed prevents the crown from being removed from the disc and thus a break-out of the bore. Greater economic efficiency: The longer range of application means that disc changes are reduced.
