Dental burrs revisited - for UK readers

noted, even if carbide coated rather than diamond, I assume the 1mm or so ones are annealed/tempered/strong enough to take a little lateral pressure. I looked to see what diamond edged mini cut-off wheels they had but those at

30GBP odd are probably pucker diamond dust, something else I could do with sometimes. somewhat related interesting discussion I recently started on uk.d-i-y on sanding discs that I'd not seen available in DIY barns or more specialised toolshops .

VERY little. You are supposed to let the speed do the work, not pressure. If you try to flex the shank at those speeds, it will destroy them.

The original context was for creating short and narrow slots in polyester pcb board , starting from some original through holes for replacement, legged pcb mount switches, with slightly different footprint. Would glass/polyester board be too much for these burrs ?

The steel shaft of those burrs probably doesn't need to be very hard, a little flexibility might be a good thing. Unlike drills, they are designed for lateral pressure. It`s the diamond (or whatever substance it is) chips that do the cutting.

The burrs in my fifteen quid cheap rechargable rotary tool do the job on fibreglass pcb material admirably.
