Special Rods

Versatile custom-made cemented carbide products 

 

  • Customized length 
  • Customized diameter tolerance 
  • Shape, number, and position of the cooling holes 
  • Variability of helix (0 - 65°) especially for blanks with short pitches of 6 to 7 mm and shorter for micro drills
  • Kidney-shaped or lenticular-shaped cooling channels in blanks for deep hole drills 
  • Reduced pitch tolerances (classification possible) for blanks up to 550 mm for helical cooling channels
  • Lengths up to 550 mm for rods with helical coolant channels and 900 mm for rods with parallel cooling channels or solid rods
  • Rod diameters from 3.0 to 34 mm for rods with a length of 330 mm and diameters up to 55 mm for rods with a length of up to 200 mm with straight cooling channels 
  • Coolant hole diameter minimums from 0.08 mm and maximums of ½ of the rod diameter 
  • Right-hand or left-hand helical twists 
  • Helical twist pitches of up to 72° possible 
  • Lateral exit holes > 0.3 mm and in forward or backward orientation
