DEFA The Adjustable Chamfering Tool

Loading the player ...
  • Controlled chamfers over a range of adjustments
  • Chamfering thickness can be infinitely adjusted directly on the tool, depending on the bore dimension
  • No reversing the spindle or indexing the work piece saves cycle time
  • Front and back or only back chamfering of bores in hard-to-machine or highly burr-forming materials 
  • Ideal for Inconel and other exotic materials
  • Dual cutting system for machining bores with longitudinal grooves, cross-bores and open bores with discontinuous cut
  • Exchangeable carbide blade with material-specific coating 
  • Blade geometry has a sliding surface that allows cutting chamfers without damage to the bore surface or of the thread during penetration
  • Widely used by the world's leading aerospace manufacturers

Available from stock for immediate delivery  in sizes
from 4 mm-36.2 mm (.157"-1.425")
