Break-in Procedure for your Bandsaw Blade


A break-in procedure, is the most important bandsawing step you can take when a new bandsaw blade is put on the machine. This step will help to ensure your band saw blade lasts longer and cuts faster and straighter.

A break-in procedure could also be called tooth sharpening and is important for both operational and production bandsaw blade cutting.

What Does the Bandsaw Blade Break-in Procedure do?

When you first receive your bandsaw blade it has a dead sharp point and a feather edge. The break-in procedure places a fine tip radius on the tooth. The radius allows the material chip to shear away from the work piece and gives the tooth tip the support necessary.

Before you begin the band saw blade break-in procedure, check the following:

  • Is the blade is correctly positioned on the band wheels and in the guides?
  • Is the blade tension is correct at 150-250 N/mm?
  • Are the band saw blade guides are positioned as near as possible to the work piece?
  • Has the chip brush and other equipment for removing chips from the blades been properly positioned and are they working correctly?
  • Has adequate cooling and lubricating fluid been entering the kerf and at the right consistency?
  • Has the cutting data been entered correctly – or is it correct (speed, feed, etc.)?
  • Has the work piece is correctly clamped?
  • Ensure the blade is not started or stopped while in contact with the work piece.
  • Ensure a new band saw blade is not used to saw in an old kerf.


Here is our suggested band saw blade break-in method:

  1. Determine the correct cutting speed and feed rate (use the WIKUS data slide rule, if necessary) based on the material to be cut and band saw machine dimensions.
  2. First, reduce the feed force as low as possible while pulling a chip
  3. Then, increase feed force over 50-100 square inches until normal feed is reached. (50 square inches – difficult-to-cut material; 100 square inches – easy-to-cut material).

For difficult to cut material, begin the break-in with a heavier feed so the material will not work harden and the tooth is not damaged.
