The all-rounder with extremely uneven pitch (EU) and additional relief grinding exclusively available from Würth for perfect countersinking.

Extremely unequal pitch


  • Optimal surface quality: exact, round, chatter-free countersinking

  • Maximum running smoothness in all materials

  • Higher cutting values possible


Exclusive, extra relief grinding


  • Up to 3x faster than conventional countersinks

  • Up to 2x more countersinking than conventional countersinks

  • Significantly less effort when used with hand drills

  • Deeper countersinking possible


For universal use


Optimal performance in the machining of almost all materials and applications due to special tip geometry and HSCo cutting material



3-flat shank


  • No spinning in the drill chuck: faster, more comfortable working

  • Optimal power transmission

  • Protects the drill chuck from damage

  • Little effort required to loosen and tighten the drill chuck


Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze
