Alpha Tools Contour Blade for Porcelain




Alpha Tools Contour Blade for Porcelain for hand curve cutting applications such as sink cut-outs on 3cm materials. Due to the nature of these materials, traditional diamond stone blades are not suitable for working on them. The hard, dense, homogeneous material is prone to chipping, which can lead to fractures.  While this blade may be used wet or dry; these types of materials require it to be used wet.


  • Use for cutting porcelain and sintered slabs
