Amana Tool 46493 Extra Long CNC 2D and 3D Carving Tapered Ball Nose 0.10 Deg x 1/2 D x 1/4 R x 1 CH x 1/2 SHK x 6 Inch Long x 3 Flute Solid Sub Micrograin Carbide ZrN Coated Reduced SHK Router Bit

Extra-Long Reduced Shank Section for Deeper Reach and Better Chip Clearance, Up-Cut Ball Nose for Superior Chip Ejection in CNC and CNC Carving Machines Amana Tool's Modern Materials Finishing Geometry (MMFG) incorporates high shear, multi-flute and a ZrN coating designed for the ultimate combination of finish and tool longevity in aerospace materials. Modern-day materials present challenges to the fabricator, using these special multi-flute edge tools featuring ZrN ceramic coating addresses these challenges with a winning geometry combination. Applications: A perfect bit for 3D carving 2D and 3D contouring, profiling, modeling and pattern making for cabinetry, sign making, furniture making and jewelry mold making Dimensional signage 3D millwork Precision 2D and 3D large scale carving Great for deep profiling Perfect for model-makers on large 3D milling profiles in abrasive EPS foam and other materialsThe industrial router bits can be used in sign making & 3D Carving industries in MDF, Plastics, Bronze, Copper, Aluminum, Foam, Wood and other materials. The simultaneous 3-axis motion with the appropriate software allows full 3D capability that provides sign and 3D model makers the ability to work with any material.The solid carbide tips cut smooth 2D and 3D contours with reduced stepping while the proprietary ZrN coating (applied by the physical vapor deposition coating process) provides high resistance to wear, sharper cutting edges, extended tool life and less friction & heat buildup.The longer bits provide deeper cuts and larger slices with fewer passes, resulting in improved productivity and less assembly. These router bits are designed to last, saving you the costs of replacing lesser quality tools. These CNC cutting tools allow you to achieve precision, depth, unparalleled accuracy, detail and clarity in foam and other modern-day materials.Benefits of ZrN Coating: Creates incredibly precise detail work Optimized flute geometry and low Total Indicated Runout (TIR) guarantees clean cuts, essentially eliminates sanding and reduces chatter when used with low TIR spindles Creates a harder and tougher cutting ceramic over carbide edge, allowing for a prolonged cutting edge life and helps to prevent the build-up/galling of material in the flutes while cutting PVD ceramic hardcoat designed for soft, gummy and abrasive materials High aspect ratio for single pass deep-reach cutting High flute volume supports high feed rates and chip loads. Has the ability to run and/or be spun much faster than uncoated tools Flute geometry optimized for cutting sign foam, sign board, hardwoods, thermoplastics and phenolic compositesExcellent for cutting: Acrylonitrile-Butadiene-Styrene (ABS) Acrylic Acrylic Stone Aluminum Brass Bronze Composite Copper Corian Coroplast* Dibond Ethafoam*** Ethylene-vinyl Acetate Foam (EVA) Expanded Polystyrene Foam (EPS) Expanded Polypropylene (EPP)** Extruded Polystyrene Foam (XPS) Fiberglass Fiberglass PCB Board Foam Board Graphite HDPE HDU 20lbs High Density Urethane MDF/HDF PALFOAM Polycarbonate (Lexan) Polyethylene (PE) Foam* Phenolics Plastics Phenolic Composites Poly (methyl methacrylate) (PMMA) Polyethylene (PE) Foam*** Polylam*** Polyurethane Foam PVC PVC Foam Board Sign Board Sign Foam Titanium Tooling Board Wood XPE (Cross Linked Polyethylene) FoamWARNING! Never attempt to cut ferrous metals with these bits. Inspect cut quality and adjust feed / speed accordingly.Note: Tools are manufactured with high balance, that allows them to run up to 60,000 RPM.Adjust your chip load and feed rate accordingly.For optimal results and extended tool life use mist lubricant system or air cooling.*Coroplast is soft plastic cardboard made with super soft, super flexible PVC. **Expanded polypropylene (EPP) is a foam form of polypropylene. ***Ethafoam, Polyethylene and Polylam are durable, flexible, closed-cell foams with excellent memory.Milling Plastics: In a milling application, all plastics tend to behave differently so attention must be paid first and foremost to heat input, as that greatly impacts surface finish and chip control. Some of Amana Tool carving tools, as you can appreciate has a very small diameter and so any material chip-loads need to reflect that small size. It can however withstand RPM's up to 60,000 RPMs. A directed air-blast to keep chips away along with cooling the tool and work piece are always welcome. Suggested starting spindle speed might be 18,000 RPM, there needs to be some experimenting on the part of the programmer to best find an acceptable finish.Cutting materials such as HDPE and Plastics its highly recommended to direct an air blast at the router bit to help keep the material cool while clearing away fragments from the cutting area. If possible run a high chip load in the order of .005" and up, per flute. Running your CNC machine at the rate of 10,000 RPM x 2 flutes x .005" per flute equals 100 inches per minute feed rate. When cutting plastics it is expected to experience some burring on top edge.
