The HSS 3-Flute Countersink is a high-performance cutting tool designed to produce precise, chatter-free countersinks and chamfers in a wide variety of materials. Engineered with three equally spaced flutes, this countersink delivers balanced cutting action, superior surface finish, and exceptional durability—making it ideal for both professional machining and general workshop use.
High-Speed Steel (HSS) Construction:
Crafted from premium HSS for excellent hardness, wear resistance, and heat tolerance, ensuring long tool life even under demanding conditions.
3-Flute Cutting Geometry:
Three cutting edges provide smoother, more stable operation with reduced vibration and chatter compared to single-flute designs.
Clean, Accurate Countersinks:
Produces crisp, round, and burr-free recesses ideal for flat-head and oval-head screws.
Improved Chip Evacuation:
Multi-flute layout allows efficient chip removal, enhancing cutting efficiency and reducing the risk of burning or clogging.
Versatile Material Compatibility:
Suitable for metals (steel, aluminum, brass), plastics, hardwoods, and composites.
Precision-Ground Cutting Edges:
Ensures consistent results, minimal surface tearing, and a professional finish.
Smooth, Controlled Operation:
Balanced flute design allows steady cutting even at high RPMs, making it suitable for handheld drills, drill presses, and CNC setups.
