Roughing router cutter downcut with right-hand Z3

Machines:
Nesting and CNC overhead routing machines.

Materials:
Softwood, hardwood and wood based panels.

Applications:
Sizing, plunging and grooving.

Technical information:
Solid Carbide bit with negative helix designed for CNC routing with chip breaker for very high feed rate applications.
• Suitable for: sizing, ramp plunging and grooving with a rough finishing.
• Downcut helix, helps the clamping of the workpiece, downward chip removal.

Working parameters
To find suggested feeding speeds see the tables below and apply the following correction factors. Materials:
Hardwood: 0,9 MDF, Chipboard: 1,1 Depth of cut:
From 1 x D to 2 x D : 0,75 From 2 x D to 3 x D : 0,5 Over 3 x D : 0,4
Rotation speed:
Suggested speeds are proportional to RPM. Examples:
Factor for 12.000 RPM: 12.000/18.000 = 0,66
Factor for 24.000 RPM: 24.000/18.000 =1,33
To maximise the tool lifetime, always set the maximum speed that delivers the needed quality of cut.
Suggested speeds for softwood: 18.000 RPM. Depth of cut equal to cutting diameter.
