Amana - A51528 3/8" Cut Diameter Downcut Router Bit

These Amana bits will produce clean, smooth cut edges in acrylic and other plastic materials. Cut Diameter: 3/8" Shank: 3/8" Cut Length: 3/8" Overall Length: 3" Flute Type: Downcut The bits are made according to strict tolerances from an exclusive high quality carbide grade and polished to a mirror finish using Amana's unique process. The Amana downcut router bits have a left hand spiral flute design which tends to push the material down onto the machine bed during cutting. This is very useful when processing thin sheet materials of almost any type which would otherwise be lifted from the bed by a more conventional upward spiral bit. The downward force created by this tool helps to hold the material in place, reducing the chance of poor or inaccurate cutting due to material movement or vibration.Materials such as laminated woods or plastics often have top surfaces which are prone to chipping when cut with an upward spiral tool. In these applications, the downward spiral geometry is
