Up cut bits provide the ability to feed faster than down cut bits as the chips are pulled out of the cut by the upward shearing action and keep the tool running cooler.

1-800-544-8436 BALLNOSE UPCUT BIT A ball nose tool is a great choice for cove and fluting operations, but is also the tool of choice when complex shapes have to be surfaced. A flat bottom bit would leave lines and a poor finish, but a ball nose bit, due to its rounded shape, provides seamless passes. Another option for this tool is a carbide insert version (pictured below) , which is always much more cost effective if the project is ongoing with a continuous tooling need.

1-800-544-8436 DOWN CUT BIT The down cut spiral bit provides a superb top surface finish, but it does run the risk, depending on application, of pushing the chips into the cut and bogging down the bit. With good dust extraction and proper chip load, this should not be a problem. It is often selected for doing grooves, dados and rebate cuts. Important to remember, always use the shortest possible cut length for dados, grooves and rebates, as the longer tools will have more deflection and can break more easily or provide poor finish due to deflection when cut length is excessive. If there is an ongoing dado or rebate cut requirement, an insert bit will decrease cost considerably within a short period of time if the tool is available in the diameter needed. (Image below)

1-800-544-8436 COMPRESSION BIT The compression bit is designed to cut materials that have a laminate, melamine, HPL, paint, paper etc. on both top and bottom surface. The cutting flutes have opposite shear angle geometry and cut toward the center of the material, thus providing clean surface top and bottom. This is the most popular style bit used in composite panel processing and is available in many different executions .ranging from a variety of carbide grades defined for wood, composite material and melamine, and also coated versions. These bits come in multiple carbide grades! Pick the right one for the job! If using ¾ or larger compression bits, an insert or a PCD diamond tool offer the lower cost option for any ongoing need.

1-800-544-8436 COMPRESSION CHIP BREAKER BIT The compression chip breaker is the best choice for cutting plywood and OSB panels where a good surface finish both sides is expected. The chip breakers, which are notches machined in an offset pattern into the flutes, facilitate faster feed rate and breaking up the larger chips created by these materials. While the chip breaker is essentially more of a hogging tool, it does provide excellent machining characteristics as well as a good finish in the compression style. Below is an insert tool option for high feed speed requirements on plywood panels and other composite materials.

1-800-544-8436 UPCUT OR DOWNCUT CHIPBREAKER BIT The up or down cut chip breaker is a great choice for cutting composite panels and plywood where a good surface finish on one side is needed. (down cut for best finish on top, and up cut for machining face-down).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
