4 pc. Modelling Carbide Tool Set

I live in Taiwan but I am British born and bred. I heard of Dura Grit from my buddies who fly R/C model sailplanes. Since these are mostly made from moulded composites these days, Dura Grit tools are the very best for making modifications, routing out glass and carbon fibre, and even making repairs.
 
Last time I was in the US I bought a set of burrs, but unfortunatley they were lost when my workshop was wrecked by a typhoon late last year. [Hence re-ordering]
 
Most bang for the buck and the tools last for ages even in our amateur environment in which I am sure there is daily misuse!

have tried many [other types of] carbide burrs, typically those machined from solid. No doubt they have their place. Problem is that when used in hand held devices such as the trusty Dremel, the inherent lack of rigidity between the cutter and the workpiece often causes sympathetic vibration of the cutter - especially if machining wood. This is sometimes an interaction between the flutes of the cutter and the grain of the wood. This is why the Dura Grit bits are so good. Because of the relatively disorganized grain pattern of the grit, vibration is rare if ever, so the finish is easier to achieve and smoother than can be obtained by a machined burr. Added to this is the fact that most Dura Grit burrs come in two different grit sizes that are ideal for roughing and pre-finishing - something that is not possible with the more expensive all-carbide bits.
 
By the way I have a PhD in materials science from a top UK university.
