Description

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.

Advantages
  • High concentricity, as the cutting head and shank are produced in one piece.
  • Optimum cutting performance due to sharp teeth made of high-quality tungsten carbide.
  • Interchangeable HSS pilot drill.
Recommendations for use
  • The recommended rotational speeds specified apply to machines capable of providing roughly constant rotational speed under load. For low-power machines where speeds drop sharply under load, the rotational speed can be increased by about 30 %. If the teeth of the cutter are not continuously engaged (e.g. on pipes or curved surfaces), the recommended rotational speed levels may be increased by up to 100 %. This will help to prevent chatter and tooth breakage when using the cutter in manual applications.
  • Tungsten carbide hole cutters are suitable for work on stainless steel (INOX).
  • In order to avoid corrosion, remove any particles which develop during work from the workpiece. Clean the workpiece chemically or mechanically (etching/polishing, etc.).
  • PFERD tungsten carbide hole cutters can be resharpened. Timely and professional resharpening substantially lengthens the tool life. Please contact your local sharpening service.
Ordering notes
  • Tungsten carbide hole cutters are supplied together with the pilot drill.
