These are usually used in routers for decorative effects in wood:
but they are potentially useful for joinery:
Next up is more boxes, this time for magazine storage — for my part I just cut open Fed Ex boxes:
But they’re not always available in a suitable size for typical magazines.
There are a number of commercial options:
So there is certainly precedent for wooden boxes — we’ll try for an inexpensive material, since this is going to be a fairly large project (sorry Nomad owners) — Luan Plywood is available at most home centers, usually as underlayment, a bit of care…
They are also useful for rounding off parts to allow rotary motion as for a hinged lid.
Unfortunately, Carbide Create does not support this endmill geometry — but using the new support for previewing a V endmill when used in a No Offset Contour toolpath, it should be possible to preview them w/ confidence by stacking a series of V endmill cuts.
Another source for these is Amana:
Industrial Quality Router Bits, CNC Router Bits, Saw Blades, Shaper Cutters, Boring Bits & Planer and Jointer Knives by Amana Tool
which has the advantage of providing rather more detailed information, in particular the tip diameter:
which allows one to set up a tool w/o the need for a test cut.
I was looking at these the other day and with a simple properly spaced grid could make for a nice soft “pillowy” background effect. like a nice tray of milk buns or somehting
To get a preview of how the tool will cut, draw up such a tool in profile (or import the DXFs):
The tool drawn above is:
With a profile in place, it is simply a matter of matching up various V endmills at appropriate depths:
(depicted are 30, 60, 90, 120, and 150 degrees)
This also brings up the fact that one could make such cuts using a series of V endmill and then sand to the desired profile.
Once the geometry which we wish to use is drawn up:
we position various V endmills relative to it:
and then draw the line for the contour toolpaths:
and create a group for the V endmill toolpaths:
and then assign the various V endmill toolpaths cutting to the appropriate depths:
until one arrives at:
Here’s a lid which uses this technique:
three_dollar_box - lid - offset roundover.c2d (501.2 KB)
which can be used on:
for a hinged design — first, verify the concept by designing and cutting a prototype in Carbide Create, then going back and updating the 3D modeling.
First consideration is size — want it to use 3 bamboo cutting boards:
sides and front and back

The fit and appearance of the lid w/ the roundover tooling is much better:
