Amana Tool - 1/4" Shank Starter Tool Set
The most common cutting diameter for end mills on the STEPCRAFT CNC is 1/8". This size allows you a lot of flexibility for cutting a wide variety of projects. Amana Tool is known as one of the best cutting tool manufacturers in the world, and we selected our favorite three 1/8" diameter end mills to get your CNC journey started. This set includes three cutting tools, all with 1/4" shanks. This shank diameter is compatible with the HF-500 Spindle, MM-1000 and the Kress 800 FME. The larger shank size creates a more stable tool with less deflection. Each tool is tapered down to 1/8" cutting diameter. All three tools feature Amana's Mirror Finish, giving you the cleanest cuts possible.
Why the "O" Flute?
Because a CNC router tends to run at a much higher RPM (10,000-25,000) and at these higher speeds you need fewer flutes to ensure that you have proper chip evacuation. If you use more flutes then you usually need to run at a slower RPM which is not always possible on a CNC router. Single "O" flute end mills allow you to run fast with proper chip evacuation.
The Starter Kit includes the following three tools:
AMANA TOOL 51454 - Single "O" flute designed for fast, clean cutting of soft metals such as aluminum, brass or copper
AMANA TOOL 51411 - Single "O" flute designed for clean cutting of plastics like acrylic, Lexan, etc. Leaves a mirror finish with no melting (with proper feed/speed settings)
