A complete range of high quality portable machines, broaching cutters and accessories for fast, cost effective drilling of accurate holes in metal. The new Magtron family of electro-magnetic hole cutting machines is a comprehensive range that provides solutions to wide range of drilling problems to 100mm diameter, both on site and in the workshop. Used in conjunction with Magtron broaching cutters, the benefits of increased productivity and cost effectiveness come from years of design development and innovation, plus well proven Magtron technological and manufacturing skills.
Broaching Cutters Vs. Twist Drill. Broaching or annular MAGTRON cutters are highly successful due to their proven ability to cut more accurate holes using less energy and giving longer tool life. Because these cutters only remove metal at the periphery of the hole being cut, on average only 25% of the material in the hole is converted into 'chips', requiring much less power than conventional twist drills - the larger the drill diameter the greater the energy saving.
The additional benefits provided by the multiple cutting edges of MAGTRON cutters include the faster feed rates that can be achieved because each cutting edge does less work, also giving the benefit of longer tool life, and unlike a twist drill, there is no 'dead' centre of the cutting action, giving more holes between sharpening. Because the cutting edges are only at the periphery of broaching cutters, they operate in a much narrower range of surface speeds than those of twist drills, so permitting drilling close to the optimum surface FPM/MPM for the material being worked.
The opportunity to greatly increase the capacity of your existing machines is another benefit of broaching cutters - you get more work from the same horsepower!
