Carbide hole cutters are professional tools for quickly and accurately cutting holes (openings) with a diameter ranging from 16 to 105 mm. They are suitable for processing alloyed and unalloyed steels, stainless steel (INOX), non-ferrous metals, and plastics (including fiberglass). Carbide hole cutters can be used on handheld drills or stationary machines. The tooth spacing (distance from tooth to tooth) of PFERD hole cutters is uneven, which helps to prevent chattering. The flat design (tool height 8 mm) is suitable for processing flat materials up to a maximum material thickness of 4 mm. The deep design (tool height 35 mm) is intended for use on curved surfaces and pipe materials. The maximum cutting depth is 32 mm.
