Solid Carbide upcut bit used for carving and sign making on hard & soft woods. Excellent for milling wood, aluminum and other non-ferrous materials. These tools are coated with a proprietary high performance *Astra coating* that allows higher speed & feed rates as well as extended tool life & increased lubricity in abrasive material. Our tools are all Made in the USA with the finest carbide available.
How Chipbreaker Bits Work:
Chipbreaker bits feature unique notch profiles, creating a serrated cutting edge, these notches break down chips into small, manageable pieces during the machining process. This type of geometry can boost your efficiency by minimizing machine downtime to clear large chips from the workpiece, improve bit life by minimizing the cutting force on the bit during machining, and allow for more accelerated speeds and feeds.
As a chipbreaker bit rotates and its cutting edge impacts the workpiece, material is sheared off from a part, creating chips. When that cutting process is interrupted, as is the case with chipbreakers in the cutting portion of the bit, chips become smaller in length and are easier to evacuate. Because the chipbreaker notches are offset flute-to-flute, a proper, flat surface finish is achieved as each flute cleans up any excess material left behind from 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.
