The CMT 152.064.322 Conical Spiral Bit Z3 is a precision-ground solid carbide routing tool engineered for high-performance 2D and 3D CNC profiling and carving. With a 3-flute spiral geometry and a conical taper angle of 3.6 deg., this bit delivers clean, tapered profiles and smooth surface finishes in wood, plastic, and aluminum. The upward chip ejection design keeps the cutting zone clear, reducing heat buildup and improving cut quality on the underside of the workpiece - making it a reliable choice for CNC operators who demand consistent results across a wide range of materials.

Key Features

• Solid carbide construction (HWM grade) - provides exceptional hardness and wear resistance, extending tool life and allowing more resharpenings compared to carbide-tipped alternatives, reducing long-term tooling costs.
• 3-flute (Z3) spiral design - three cutting edges distribute cutting load evenly, enabling faster feed rates and a finer finish on profiled surfaces in CNC applications.
• 3.6 deg. conical taper angle - creates precise tapered channels and conical profiles suited for 2D and 3D CNC carving, giving workpieces clean, drafted walls without secondary operations.
• Upward chip ejection - actively pulls chips away from the cut zone during routing, preventing recutting of material and reducing heat - especially beneficial when machining plastics and aluminum where chip re-welding is a concern.
• Excellent finish on the lower side of the workpiece - the cutting geometry is optimized to leave a smooth surface at the base of the cut, minimizing sanding or cleanup time after CNC operations.
• Right-hand (RH) rotation - compatible with standard CNC routing spindles, ensuring straightforward installation and setup on conventional machines.
• 1/4 in. shank diameter - fits a wide range of CNC router collets and standard router collet sets, offering broad machine compatibility without adapters.
• 1 in. cutting height with 3 in. total length - the generous reach allows full engagement in typical CNC profiling passes while the extended overall length provides clearance for workholding and fixturing.

Why This Product

• Designed specifically for 2D and 3D CNC profiling and carving in plastic, aluminum, and wood - this is not a general-purpose bit but a purpose-built tool for CNC operators working across multiple material types in production and custom fabrication environments.
• The combination of a 3-flute geometry and upward chip ejection addresses one of the most common CNC routing challenges - chip management - keeping cuts clean and reducing the risk of material damage from chip recutting, particularly in plastics and non-ferrous metals like aluminum.
• Solid carbide construction with a 3.6 deg. taper angle makes this bit capable of producing precise conical profiles in a single pass, eliminating the need for multi-step profiling operations and improving throughput on CNC routing projects.
• With a 1/4 in. shank and right-hand rotation, this bit integrates directly into standard CNC router setups without specialty toolholders or adapters, lowering the barrier to use for shops already equipped with conventional collet systems.
