HSSE 60º angle milling cutter
The HSE60A series is a professional-grade cutting tool specifically designed for precision machining of 60° taper holes and countersunk holes. Utilizing HSSE high-performance high-speed steel as its base material, it features a 3-flute, 60° precision-angled cutting edge with a mirror-polished finish. This design combines high toughness, excellent red hardness, and sharpness retention, resulting in strong cutting stability and high edge wear resistance. It is an ideal choice for chamfering and deburring countersunk and taper holes in materials such as aluminum alloys, steel, stainless steel, and low-carbon steel, suitable for both batch and precision machining needs. The chamfering end mill produces workpieces with smooth, clean edges, eliminating burrs and sharp edges.

Design details engineered for accuracy, tool life and process stability.
Forged from high-quality HSSE high-speed steel, containing tungsten, molybdenum, and vanadium alloying elements. The base material has a hardness of HRC62-64, exhibiting excellent red hardness and maintaining cutting hardness even at 800℃, preventing edge softening.
The cutting edge is ground using an ultra-precision grinding machine, with an angle tolerance controlled within ±0.05°. High-precision corner forming perfectly matches the 60° taper surface machining requirements of screw countersunk holes and rivet holes, eliminating the need for secondary grinding.
The three cutting edges are symmetrically distributed, evenly distributing cutting force, significantly reducing machining vibration, preventing taper surface runout and dimensional deviations, and achieving a surface finish of Ra0.8μm or less.
Compared to ordinary high-speed steel, toughness is increased by 30%, capable of withstanding cutting impacts, suitable for machining medium-hard materials such as steel and stainless steel, solving the problems of easy chipping and short lifespan of ordinary cutting tools.
Shallow grooves with a large chip capacity ensure smooth chip removal without jamming, especially suitable for chip removal during countersunk hole machining, preventing chips from scratching the workpiece's tapered surface.
The substrate has a hardness of up to HRC63, combining high hardness and toughness, with twice the chipping resistance of ordinary chamfering tools.
Universal straight shank design, compatible with ER collets and spring collets, allows for quick clamping on CNC machining centers, high-speed milling machines, and drilling machines, eliminating the need for special fixtures and maximizing tool change efficiency.
