I'll ask the (stupid) question first, can I use a 19mm TCT bit in a router?
I drilled my first dog holes in my new workbench today using a brand new new TCT 19 mm bit. It's the first time I've ever used a TCT bit and although it cut the 70mm hole in the jarrah somewhat easier than a spade bit, I was disappointed in the way the hole wandered off vertical. (Yeah, I know I should have drilled the holes before I put the bench together). I was holding the drill vertically up against a vertically clamped corner made of 2 MDF boards which was vertical according to my spirit level. Anyway the bit wandered off to my left by about 3mm over a hole depth of 70 mm. The second hole was slightly better but still maybe 2 mm off centre.
So, my next route is plunge routing and rather the fork out $$ for a 19 mm router bit I wondered if the TCT bit could be used in a router. One more thing, the TCT bit has a 3/8"? shank so are there 1/2 to 3/8 shank coverters for router available anywhere?
If this is a stupid suggestion please say so - I don't particulary feel like experiencing WC shrapnel flying around the workshop.
Cheers
