Freud CNC Router Bit 72-101 1/4 Inch Up Cut Spiral Ball Nose (Solid Carbide 1/8 Inch Radius 3D Carving 1/4 Inch Shank)

Freud 72-101 1/4-Inch Solid Carbide Up-Cut Spiral Ball Nose CNC Router Bit

The Freud 72-101 1/4-Inch Solid Carbide Up-Cut Spiral Ball Nose Router Bit machines intricate 3D topographical profiles, deep contours, and dimensional carvings in hardwood, plastic, and non-ferrous metals. Engineered with Freud's proprietary TiCo Super Density Carbide and a specialized 1/8-inch radius tip, this 1/4-inch shank CNC bit shears clean, fluid lines that drastically reduce post-process sanding. Featuring an up-cut geometry that actively pulls chips and dust away from the cutting path and an advanced Black I.C.E. coating that reduces pitch buildup and heat friction, this industrial carving bit delivers up to 2X the tool life of standard uncoated carbide.

Best Used For:

• CNC 3D Contouring & Carving: Machining topographical maps, decorative furniture panels, and fluid architectural millwork designs.
• Deep Profile Plunging: Sinking into dense hardwoods and solid surface materials while aggressively evacuating chips upward to prevent bit breakage.
• Plastic & Aluminum Routing: Milling non-ferrous metals and acrylics smoothly without melting or welding chips to the cutting edge.

Key Performance & Safety Features

• TiCo High-Density Carbide: Proprietary titanium-cobalt micro-grain carbide matrix resists extreme wear for extended cutting sharpness.
• Black I.C.E. Coating: Advanced non-stick barrier minimizes heat-inducing friction and prevents wood resin from binding to the flutes.
• Up-Cut Spiral Geometry: Draws chips and sawdust vertically out of the channel to prevent overheating and ensure a glass-smooth bottom finish.
• Precision 1/8-Inch Radius: True ball nose spherical tip machines smooth, continuous gradients without step-over ridges.
• 24,000 RPM Rating: Dynamically balanced for high-speed operation in automated CNC gantries and handheld plunge routers.

Technical Specifications

Pro-Tip: Use this up-cut spiral bit when you need rapid material removal during deep CNC contouring; the upward shear action clears chips efficiently to prevent the bit from burning the wood, but always ensure your workpiece is securely clamped to prevent lifting.
