Extra-Long Reach Flat Bottom (End Mill) CNC 2D and 3D Carving Solid Carbide Spiral, 3-Flute ZrN Coated Router Bits with Reduced Shank, In-Stock and Ready to Ship Today! Large selection of Industrial Quality Extra-Long Reach CNC Router Bits.
The industrial router bits can be used in sign making & 3D Carving industries in MDF, Plastics, Bronze, Copper, Aluminum, Foam, Wood and other materials with machines such as "i-Carver", CarveWright™, CNC Shark®, ShopBot® and Datron. 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.
WARNING! 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.
