Tersa blade - what type to buy?

bp122 · 18 Nov 2022

Hello all

I have a 260mm planer thicknesser and a lunchbox thicknesser, both needs their blades to be replaced / sharpened.
But I thought it might be a good idea to get some new blades as I have a few urgent projects and would like to start with new blades.

I have heard about Tersa blades a lot before, but don't know what type to get.

Which ones of these are a good compromise between cost, sharpening, longevity, durable edge etc.?
And which ones are to be steered clear of, if any?

Thank you for your help

If you have a standard block (where the blades mount to) you cant / shouldnt use Tersa blades. You need a specialised block for them.

Ah that buggers the plan!

Anyone know where best to get the normal planer blades from?

I tried to buy 2 new blades for a large DeWalt planer......was quoted £60 odd for the originals.....
stuff that so got some from china direct about £15 for the pair.....because I was doing rough work with suspect dirty timber....
honestly cant tell the difference....
prob coz they all made there.....

I looked at the cost of a Tersa kit for another planer but the cost was as much as a Helix....
someone on here suggested another make of blade/block kit but I cant find the reply anymore....
