CNC Router Bits & Cutting Bits at Rockler

For more on regular milling cutters most of which can also be used on a router except for larger tooling like Face Millscheck out our Total Guide to Milling Cutters. For an even more basic Cnc Bits For Wood 400 view of how to choose the right cutter, try our series on choosing cutters for mills and routers.

Depending on which way the spiral goes on a cutter, you get a cutter that either moves the chips up or down. Whichever way the chips are going, there is also force exerted on the workpiece in the same directions. So, an upcut will move the chips up and out of the cut, and it will tend to pull up on the workpiece. BTW, the conventional endmill world refers to some cutters as left Cnc Drill Bits For Wood Zone handed or right handed.

This is not the same thing because it refers to the actual spindle rotation. An upcut is a conventional endmill for all intents and purposes. For wood and materials that may chip, it has the disadvantage that it wants to pull chips along the top edge. Since a downcut pushes down, it leaves a cleaner cut on top, but can fray the bottom edge.

Workholding is another issue. The upcut wants to pull up on the workpiece. A vacuum table helps Router Bits For Wood Cnc 5g a lot with this. Cnc bits for wood optimization, why not always use the Downcut, get cleaner cuts, and keep the workpiece firmly pressed down onto the table? The answer is that the downcut forces the chips down to the bottom of the hole, which is far from ideal.

If you read the CNCCookbook blogs, you will have heard me talking about the need to be paranoid about clearing chips. It is less a problem with wood than metal, but it is still very much a problem. Consider using a downcut for a final finish pass where there are fewer chips to clear and where you want to avoid chipping the top edge of the cut.

When using our G-Wizard Feeds and Speeds softwaretreat upcuts as normal endmills. G-Wizard is actually the first feeds and speeds calculator designed especially with the needs of CNC Router users in mind.

One other tip: a lefthand endmill smaller than the diameter of a stuck screw can make a great way to remove the screw.

The flutes literally go one way for the bottom half of the cnc bits for wood optimization length and the other way at the top.

Compression cutters are for plywood, composites, and laminates. Given the chip clearing problems, and cnc bits for wood optimization desired use to prevent chipping, G-Wizard has a special setting for compression cutters. The edges are serrated to break up the cnc bits for wood optimization into smaller pieces and really move some material fast when roughing.

I like these bad boys a lot: check out our article on roughers for more info. Cnc bits for wood optimization helical flute allows the edge to gradually ramp up its engagement on a chip. For a straight flute, it happens all at once as the entire edge slams into the workpiece. For CNC, they seem like a waste, and I would definitely never use on on anything but wood or plastics. According to Wealden Toola spiral fluted cutter can go 3x faster and leaves a better finish.

OTOH, they are cheap. One machinist wrote that he mostly uses straight flute cutters on wood projects because they are so much cheaper. Spoilboard Cutters are similar to facemills and fly cutters found on conventional CNC milling machines. Their purpose is to make the entire surface of a spoilboard flat as quickly as possible.

It ends up spinning on the end of the bit. I have on more than one occasion had a plug spin inside a cut…. Router fires can be dangerous, check out our article on them.
