The Jetbroach and Hi-broach annular bits have been developed in an independent way; bits with diameters up to 75 mm feature a fast change system, thus reducing the equipment setup time.
Agility and long life assurance.
The Jetbroach models are made of tungsten carbide and wide pads (or hard metal), thus assuring long lifetime and high cutting resistance. They are available with diameters from 12 mm to 100 mm, and three length options.
The Hibroach models are made of high-speed steel; they are available with diameters from 12 mm to 52 mm, and two length options.
The guide pins are made of tungsten and exhibit a variety of dimensions, for each diameter and length of the adopted bit.
The recommended speed to cut steel and cast iron is 30 to 50 m/min; for bronze, 50 to 70 m/min, and for aluminum, 70 to 90 m/ min. The Jetbroach and Hi-broach annular bits can be used in machine tools with the help of brackets.
All annular bits can be used in tools of other brands.
