Ferrous Metal Cutting
For ferrous metals we have a range of metal cut-off wheels that provide outstanding sectioning results. When choosing the correct Aka-Cut cut-off wheel you obtain a plane sample surface with minimal mechanical deformation and thermal damage. Long lifetime and high reproducibility are guaranteed when using our cut-off wheels of highest quality. Different diameters are available for all our abrasive cut-off wheels. Our precision cut-off wheels are available in 150 mm dia. Our metal cut-off blades for ferrous usage are all based on Al2O3 - the most efficient abrasive for these materials.

Ferrous Cut-off Wheels
Aka-Cut Fe60 is the optimal choice for ferrous metals and steels with an approximate hardness of 60 HRC or in the range of 500-1000 HV.
Aka-Cut Fe50 is the optimal choice for ferrous metals and steels with an approximate hardness of 50 HRC or in the range of 350-700 HV.
Aka-Cut Fe40 is optimised for ferrous metal cutting with a hardness of 150-700 HV and only available as precision cut-off wheel.
Aka-Cut 500 HV is the optimal choice for ferrous metals with a hardness of approximately 250-500 HV. Al2O3 ensures the best cutting results possible for ferrous metals and steels. Aka-Cut 500 HV is reinforced with a special fiberweb on both sides for maximum durability. This means that it can better withstand the internal stress and tension in surface hardened workpieces and the risk of wheel breakage is therefore reduced.
How are cut-off wheels optimised for different materials?
With the same abrasive, the binder is modified to suit the material to be cut. A soft binder, releasing grains faster assures that the abrasives are always sharp when cutting hard materials, and a hard binder keeps the grains for a longer time and thus increases the lifetime of the cut-off wheel when cutting softer materials. Ferrous metals/steels come in a wide range of hardness. To accommodate these differences we offer a variety of wheels for ferrous metals.
Which type of cut-off wheel should I use for cutting ferrous metals?
For almost all types of steels and cast iron Al2O3 cut-off wheels are used.
Why is Al2O3 used for cutting ferrous metals?
Al2O3 is a rather durable abrasive that will wear slowly and thus give a long lifetime to the cut-off wheels. Due to its more blocky/round grain structure it can introduce deeper deformation in soft and ductile materials, therefore SiC is used there.
