• The shear cut virtually eliminates tear-outs.
• 40x lifetime from our proud carbide insert.
• Feed faster and higher work efficiency.
• Producing much smaller chips and your dust collection system will function more efficiently.
• Changing blades is effortless and does not require adjustment.
• No need to re-sharpen the blades any longer.
• Dramatically reduced noise.

Note: We have recently changed the compatible blades from 15x15x2.5mm-R150 blades to 15x15x2.5mm-R150-4R0.5 blades. Please do not use the different blades mixedly (If you are not sure which blades you purchase, do not hesitate to contact us). In case you're unable to locate a cutter head that matches your machine model, we also provide an option for a custom cutter head.
