With their 6-hole “see through” technology Holey Galahad tungsten carbide discs are phenomenal for wood carving and sculpting. They leave a very coarse to even finish on contoured, convex and flat surfaces.
Holey Galahad discs fit most standard 4-1/2″ to 5” and metric 115mm to 125mm angle grinders. There are eight 7/8″ x 4″ (22mm x 100mm) discs to choose from in four grits (from extreme coarse to fine) and in round and flat profiles.
There’s no stopping to continuously lift the angle grinder – now you can see what you’re doing and where you’re going versus the usual method of carve, lift, check – repeat. Holey Galahad discs are very fast, easy to control, can be used on both face and edge surfaces and there’s no heat buildup. The discs are made with high quality structured tungsten carbide teeth that are meticulously bonded to steel discs over the total cutting surface in a 5-stage patented process. Discs can be cleaned and reused multiple times, saving hundreds of dollars in flap disc sanders, time, labor and effort.

I checked out the video and visited the King Arthur website. The comments are very positive on this product and it seems to do the job very efficiently. The downside is that the price is in USD and with shipping the total cost is over $125 CAD per disc if you buy a set of 4. It also ships from the US so there may be the additional cost of duty and Canadian taxes.
You can get a single Kutzall disc from Lee Valley for less than $100 CAD including shipping and taxes. Other than the holes, this disc seems to perform just as well as the Holey Galahad.
