Break-in	Break-in procedures: For long blade life.
	For extended blade life, less blade changes and best payback of your tool cost, special break-in procedures should be adhered to. Overload of the razor-sharp tooth tips should be avoided at the start of cutting operation. Aggressive cutting with a new blade lead to premature tooth breakages. Correct break-in will control the gentle rounding of cutting edges. Starting feed should half of final speed rate at the recommended cutting speed (Recommendations) for the first 300 – 500 cm² cut surface. After that, feed rate should be gradually increased for maximum cutting rate as mentioned above (Right Feed Rate). Should vibrations or noises occur at the beginning of the cutting operation, cutting speed should slightly be adjusted.
