Amana Tool Compression Bits

Amana Tool compression bits combine upcuts and downcuts. The result is a clean top and bottom cut surface.  In order to get clean top and bottom surfaces, you must ensure that your first pass is below the upcut portion of the bit; otherwise, you’ll get results similar to using just an upcut bit. You can extend the life of your bit and ensure that the entire piece is perfectly trimmed on top and bottom by using a ramp in, plunging into the material over a distance instead of all at once, and a lead in, starting outside the design to reach the pass depth, to the cut. Compression bits cut in one pass. As long as the first pass is below the upcut portion of the bit, if your machine is unable to handle that depth of cut, you can cut in multiple passes.

For every project, compression bits won’t replace downcut and upcut bits. When cutting a shallow pocket with a clean top surface, a compression bit will not be below the upcut portion. The top surface will become frayed or chipped as a result. A deep profile cut requires extra chip evacuation, so an upcut bit is your best option. To prevent recutting chips and wearing your bits, you should do this. Small hobby-style CNC machines may have trouble taking a deep enough first pass to get below the upcut portion. To stay within your machine’s capabilities, you should use an upcut or downcut bit for profile cuts. When used correctly, compression bits are the best way to ensure a clean top and bottom surface on your cut.
