Tungsten carbide hole cutters are professional tools for quick, precise hole-cutting (cut-outs) with a diameter of 16 to 105 mm. They are suitable for working on alloyed and non-alloyed steels, stainless steel (INOX), non-ferrous metals and plastics (including GRP). Tungsten carbide hole cutters are used on hand drills or on stationary machines. PFERD hole cutters have an irregular tooth pitch (distance between teeth) to prevent tool chatter. The flat version (tool height 8 mm) is suitable for work on flat materials up to 4 mm in thickness. The deep version (tool height 35 mm) is suitable for use on curved surfaces and pipe materials. The maximum cutting depth is 32 mm.
