Countersink with Pilot to Reduce Chattering

  • Countersink Tools with Pilots are designed for countersinking, chamfering or deburring.
  • Each size may be used on a wide range of hole diameters. 
  • Countersinks with integrated pilot drills reduce chattering by allowing the pilot to closely fit into a predrilled hole.
  • Countersink Tools can be used in a rigid tool holder such as a collet or end mill holder, or with the 2L CNC Countersink Depth Stop Tool.
  • Solid carbide shanks ensure maximum rigidity to reduce chatter.
  • Custom pilot sizes, number of flutes, or different included angles are available on any Countersink with short lead times.
  • Premium, Ultra-Fine, Nano Grade Solid Carbide for maximum tool strength and durability.
  • Manufactured in house.
  • Many tool sizes in stock & ready to ship.
  • 2L also produces Single Flute Countersink Tool Bits.
