Know someone who engraves stones, artistic rather than memorial, he`s
on to his third dremel in 5 years, of heavy abuse, if they`re used
heavily they are well made.


Similarly, site metallurgists use them when examining welds. Expensive,
but they tolerate abuse. For domestic use a Draper or Lidl/Aldi should
be OK.

Rechargeables can be useful (e.g. on the car) but battery life not very
good. Get a mains one for continuous use or if you don't need portability
