What do you have videos? ... links?
I did a video series on shapers for small shops which includes some discussion about chip limiter tooling, but it's sorta buried in amongst the weeds!
Here's the nitty gritty from the HSE in the UK: Came from here: http://www.hse.gov.uk/woodworking/tooling.htm
Benefits of chip-limited tooling
The limiter reduces the depth of cut so Ďkick backsí are less likely to occur.
Ejection of the tools was common with the old style cutters as they were only held in place by the friction from clamping bolts. Chip limited tooling has two ways of securing the cutters, preventing ejection.
The reduced depth produces a better finish, so less sanding is required, reducing the health risk and improving production.
Chip limited tooling is much better balanced so there is less vibration when it runs. This has the following benefits:
With high revolution machines such as CNC routers vibrating tools can be ejected with serious consequences;
Less vibration means there will be also be a reduction in noise levels. In addition, noise levels will also be reduced if the tool body is made from aluminium, a feature of some chip limited tools. Lighter aluminium bodies also reduce forces on the motor during braking as well as making the tools easier and safer to handle.
Less vibration means that the tool cuts more efficiently so it can therefore have a three to four times longer tool life. In addition, there will be an improved finish and less wear on the shaft and bearings of the machine.
The old style tooling requires a lot more skill and time to set up correctly. Chip limited tooling is simpler to set up and therefore reduces down time during changeover. Also, as it is more likely to be right first time less timber is wasted. One head can also have several different profiles which also reduces set up times.
