HSS Zero Flute Countersink (90°/82°/100°/120°)

The Zero Flute Countersink is a precision-engineered cutting tool designed to create clean, chatter-free countersinks and chamfers in a wide range of materials. Featuring a single-flute cutting geometry, it provides smooth, controlled cutting action with minimal vibration, making it ideal for achieving professional-grade results in woodworking, plastics, soft metals, and composite materials.

Key Features

• Single-Flute Design (Zero Flute):
  Offers superior chip evacuation and reduces chatter for smoother, rounder, and more accurate countersinks.

• Clean, Burr-Free Cuts:
  Produces crisp, clean edges with minimal surface tear-out, especially effective in wood and softer materials.

• Precision-Ground Cutting Edge:
  Ensures long-lasting sharpness and consistent cutting performance.

• Versatile Applications:
  Ideal for countersinking screw heads, deburring holes, chamfering edges, and enlarging pilot holes.

• Wide Material Compatibility:
  Works efficiently on hardwood, softwood, MDF, plastics, aluminum, and brass.

• Durable Construction:
  Typically manufactured from high-speed steel (HSS) or carbon steel for strength and reliable tool life.

• Smooth Operation:
  The flute geometry minimizes grabbing, making it easy to control even when used with handheld drills.

Common Uses

• Creating countersinks for flat-head screws

• Deburring drilled holes

• Chamfering edges and openings

• Light hole-sizing or tapering tasks
