Friction drill bit Standard with collar

The solution for increasing wall thickness by displacing the raw material. The increased wall thickness enables the creation of threads with high pull-out forces and high overtorque in sheets of steel, stainless steel, copper, aluminium, bronze etc. starting at a thickness of 0.5 mm. Alternative to rivet and weld nuts.

Benefits


  • Chipless drilling and thread cutting

  • No waste and disposal costs

  • No additional investment or storage costs

  • Reduction in work steps

  • No extraneous material necessary

  • High level of process reliability

  • Solid carbide tools offer a particularly long service life

  • Thread length is multiple times the original material thickness
Notice
  • A lubricating paste must be applied to the drill bit every 2nd or 3rd hole in order to increase its service life. Recommendations: HSP 1400 high-temperature lubricating paste.

  • Using a collet chuck with cooling fins is strongly recommended, as a very high heat is generated during the drilling process (700-800°C), and the collet chuck with cooling fins will significantly reduce the heat transfer to the machine spindle. Not using this type of collet chuck can result in damage to the power tool.

  • The use of thread formers is recommended, as the pull-out resistance and overtorque are significantly higher than when using machine taps.
