| Speed & Feed Rate? Hello to all! I am new in this forum and I would like to help me in a minor problem! I have a hole 8.5mm and I would like to make a tap (M10). The depth of the hole is 22mm. What will be the Speed and the Feed Rate? Thank you in advance! dcis77! |

| One Question again! I have a carbide 16mm with 6 flutes (50mm long). I want to pass around a piece of steel to take 0.1 lateral oversize. I use 1800 RPM for Speed and Feed Rate 400. Is this correct? It is very noisy with these values. My cnc-machine is "screaming". What Spindle Speed and Feedrate is recommended? Thanks again! dcis77 |

| If it's screaming like this the carbide tool doesn't last. You can try slow down RPM and increase feed. Or using a high speed tool, and slow down RPM. Konrad |
