So, I read a review in one of the woodworking mags, they like Ti
coated blads - longer life, smoother cuts. I saw 10" blades at the
orange BORG (being a spacecase, I can't remember the brand - a little
help, foks?), and thought the price wasn't horrible. Has anyone any
experience with them? How do they compare to Freud or Forrest?
I use coated cutting tools daily, on things that do matter. The usefulness
of this coating drops off to being insignificant on materials as soft as
hardened aluminum. On wood, it would make no difference. You are right, the
reason for it showing up on so many cheap cutting tools is marketing, as it
looks high tech and is very cheap to apply.
Why, and which mag so that we can ignore any more rubbish they spout.
A TiN coating on a woodworking blade is pointless. Although some TiN
coatings are useful, these aren't the coatings you see at the Borg. In
general these days, gold coloured coating means cheap rubbish and run
away from it.
There are lots of important things that make a good sawblade work better
than a cheapie. TiN coating isn't one of them.
I have to disagree. With the TiN coating, the sawdust is given a positive
ionic charge so when they pass through the dust collection piping it will
reduce the likelihood of an explosion. It is also important to keep the
coating clean; wipe it down with acetone weekly. Just don't get the acetone
on your hands or you will get zits on your ass.
Surely it's easier to just screw an earth wire to the sawblade ?
Some sawblades have little copper slugs set into their anti-vibration
slots. Not many people realise these are actually soldering points for
the earth wires.
