Solid Carbide Spiral Flute Chamfer Mill (60° / 90° / 120°)

Our premium Solid Carbide Spiral Flute Chamfer Mills are engineered for high-precision CNC machining. Unlike straight flute tools, the spiral flute design provides a smoother cutting action, significantly reduces vibration, and ensures excellent chip evacuation, making it ideal for both high-speed deburring and decorative chamfering.

Product Function

Chamfering & Deburring: Removing sharp edges and burrs from workpieces.

Spotting: Creating a precise starting point for drills to prevent walking.

V-Grooving: Precise V-shaped slotting and engraving.

Contouring: Edge profiling on various metal and non-metal materials.

Product Features

High-Grade Tungsten Steel: Manufactured from micro-grain carbide for exceptional hardness and wear resistance.

Spiral Flute Design: Optimized helix angle for cleaner cuts and faster chip removal compared to straight flutes.

Wide Range of Sizes: From micro-diameter 0.3mm for electronics to 12mm for heavy-duty industrial use.

Multiple Angles: Available in 60°, 90°, and 120° to meet all standard engineering requirements.

Long-Reach Options: Extended lengths (up to 100mm) available for deep-hole or hard-to-reach chamfering.
