Amana Tool 51776 CNC SC Spiral O Single Flute, Aluminum Cutting 1/4 D x 1-1/4 CH x 1/4 SHK x 3 Inch Long Down-Cut Router Bit with Mirror Finish

To be used only on CNC machines and routers with automatic feeding. Solid carbide spiral 'O' flute aluminum cutting router bits use the highest quality sub-micrograin carbide, have a special proprietary edge processing system and feature a super high polished cutting edge with a unique “mirror finish”, resulting in clean cuts, less chance for chip re-welding, a superior surface finish and a longer tool life. The spiral ‘O’ flute sharpening/finishing process increases feed rates, allowing for more linear feet routed in less time.

Excellent for cutting:

*Durabond is a polyethylene core with 0.3mm colored aluminum sheet on either side. It is a pre-finished product that requires no decoration.

Testimonial: "Why didn't you tell me that the bit (#51408) would cut endlessly through my material without ever breaking? I wouldn't have wasted my money ordering 4 of them!! Hehe, seriously, this bit is churning out some beautiful work. I've doubled my speed and cut off my oil mist." Dennis, LA

Available in both metric and inch sizes, these router bits are specifically designed for a variety CNC machining applications. Continuous improvements in cutting performance, the unique carbide polishing process, tool design & geometry make these router bits perfect for routing signs and displays. Signmaking (signcrafter) router bits were originally developed in Europe specifically for professional sign makers. Today, CNC routers have become the tool of choice for sign makers, moving beyond printers and vinyl cutters.
