Router Bits

[Invisible-Man]

Hi, could anyone advise how many worktop Butt and Scribe joints should you be able to get from 1 router bit and can you re-sharpen them, I done 1 joint and 3 end cuts and the router bit seems to have got slightly blunt, slight smell of scorching. The reason I ask is that they are rather expensive!

Is it more cost effective to buy dearer ones (maybe last longer) or cheaper ones?

Many thanks

around one and a half is right

if you cut off the majority with a jigsaw[leave around 4mm] but only if you know your jigsaw wont wander off line

its cheaper in the long run to use replacable cutter blades

Like big-all I find I get a couple of joints or one joint and maybe a couple of ends from decent quality brazed tooling, but I use replaceable tip stuff most of the time, now, from Wealden Tool (ref. K69420). I tend to keep a couple of "part worns" with the router for doing the connector cut-outs. When you grind brazed TCT cutters the diameter is reduced so you can't regrind and use for worktops I'm afraid - the conector holes are not critical, so regrounds are OK for that. The TC-RT stuff has constant diameter, but lasts no longer that decent brazed, but you do get two edges per tip. I've had cheap brazed cutters which won't even do one joint properly, so they're really not an option when you're cutting £100 or more worth of top.

So about £10 per joint would be a fair allowance?

Many thanks for all the information
