90° TIALN Three-Cutter Milling Cutters SET
Countersinks are conical cutting tools used to machine a tapered seat in a drilled hole so a screw head sits flush or recessed, improving fit, safety and surface finish. They are used on metals and plastics with drills and milling machines.
Available in multiple cone angles, diameters and lengths, with HSS, HSS-Co (cobalt) and coated options for higher wear resistance and cleaner cutting. Choose reliable tools from Yg & Hepyc for consistent results.
Suitable for machine shops, fabrication and maintenance. When selecting, match the screw head angle, workpiece material and the required finish.
Conical End Mills
The countersinks (also known as small milling cutters or countersinks) are cutting tools used to form a conical recess at the mouth of an existing hole. Their main purpose is to allow the countersinking (milling) of a screw head, so that it sits "flush" with the surface of the material.
- Cutting Angles:90°: The most common angle for standard screws (metric thread).60°: Used mainly for edge "breaking" (deburring) and for centering.82°: Standard angle for screws according to American standards (UNC/UNF).
- Design Types:With hole (Zero Flute): Ideal for soft materials and thin sheet metal, as they do not "clog" and provide a very smooth finish.With 3 flutes (3-Flute): The most classic type for stable cutting without vibration in harder metals.
- Applications: In addition to countersinking screws, they are essential for removing burrs (deburring) after drilling, ensuring safety when handling components.
