*Astra Coated* Bits&Bits 540-SRF500CB – 1/2″ Up-Cut Chip Breaker – 2″ LOC

What is a Chipbreaker?

Chipbreaker bits have unique notch profiles in the flute, creating a serrated cutting edge that breaks down chips into small, manageable pieces during machining. This feature improves bit life by making shorter chips which allows for quicker chip evacuation, reducing cutting force and allows for more accelerated speeds and feeds. The offset flute-to-flute arrangement of chipbreaker notches ensures a proper, flat surface finish as each flute cleans up excess material left behind by previously passed flutes.

What is an UpCut bit?

UpCut bits allow for rapid cuts since the tool clears the chips away from the material.  While Ideal for cutting thicker materials, this type of tool is not recommended for thinner or softer materials. They are more likely to tear the top surface with the cutting edges because they’re pulling the wood fibers up while cutting. When cutting laminated materials, such as plywood with a thin top veneer, that can matter a lot. This type of bit is used whenever the best finish is needed on the bottom side of a part.
