High-Performance 90° × 63 mm Countersink Cutter
This 90-degree, 63 mm countersink cutter is a precision tool designed for creating clean, accurate conical recesses in a variety of materials. It’s excellent for countersinking fasteners, deburring holes, and preparing workpieces for flush fittings in demanding machining applications.
Key Features
-
Wide 63 mm Diameter: A large-diameter cutter capable of handling sizable countersinks — ideal for large bolts, heavy assemblies, and deep chamfers.
-
90° Cone Angle: Matches standard countersunk head screws and bolts, providing the correct seat angle for fasteners.
-
Durable Construction: Likely made from high-speed steel (HSS) or similar tool-grade material for strength and longevity. (Analogous cutters use HSS or HSS-XE.)
-
Morse Taper or Cylindrical Shank Options: Many large countersinks use a Morse taper shank for rigidity — for example, a 63 mm cutter with MT4 shank.
-
Precision-Ground Flutes: Well-machined cutting edges ensure smooth chip evacuation and reduced chatter for a high-quality finish.
Why Choose This Cutter?
