The CMT 152.064.082 Solid Carbide Conical Spiral Bit is a precision-engineered 3-flute CNC routing tool designed for high-quality 2D and 3D profiling and carving in wood, plastic, and aluminum. With a 1/32" tip diameter, a 6.2 deg. conical angle, and a 1/4" shank, this right-hand rotation spiral bit delivers clean tapered profiles and conical channels while actively ejecting chips upward to keep the cut path clear. Whether you are machining intricate relief carvings, tapered inlays, or detailed 3D contours, this solid carbide bit maintains cutting precision across demanding CNC routing applications.

Key Features

• Solid Carbide (HWM) Construction - manufactured entirely from hard metal carbide for superior wear resistance and edge retention, reducing the frequency of tool changes during long CNC runs.
• 3-Flute (Z3) Spiral Design - three cutting edges share the workload to produce a smoother finish on the underside of the workpiece compared to single or double-flute designs, minimizing post-processing cleanup.
• Upward Chip Ejection - the spiral geometry actively pulls chips up and away from the cut zone, preventing recutting and reducing heat buildup that can cause surface burning or bit wear.
• 6.2 deg. Conical Angle - the precisely ground taper allows the bit to create consistent conical profiles, tapered slots, and contoured grooves with repeatable accuracy pass after pass.
• 1/32" Tip Diameter with 1/64" Radius - the fine tip geometry enables highly detailed carving and tight-radius 3D profiling that coarser bits cannot achieve, making this tool well suited to intricate CNC artwork and engraving work.
• 1" Cutting Height on a 3" Total Length - the extended reach-to-diameter ratio allows the bit to access recessed areas and deeper relief work without sacrificing rigidity.
• 1/4" Shank - fits a wide range of standard CNC spindles and router collets, providing a secure grip and minimizing runout during high-speed passes.
• Right-Hand (RH) Rotation - compatible with standard CNC routing machines and conventional router setups for straightforward spindle compatibility.

Why This Product

• Designed specifically for 2D and 3D CNC profiling and carving, this bit addresses the need for a single tool that can handle both flat-plane profiling and complex sculptural work in wood, plastic, and aluminum without switching cutters.
• The 3-flute spiral geometry combined with upward chip ejection delivers an excellent finish on the lower face of the workpiece, reducing sanding and finishing time after cutting - a meaningful advantage for production CNC environments.
• The fully solid carbide body provides the durability needed for extended runs in abrasive materials like plastics and aluminum composites, where carbide-tipped alternatives wear more quickly.
• The 1/32" tip diameter and 1/64" radius make this bit one of the more refined options for detail-oriented CNC work where tight geometry and fine surface quality are required - suited to sign-making, mold work, and artistic carving applications.
