Bi-metal Bandsaw blade woes

[Ian]

I just got a 131" 3/4" 4TPI Bi-metal blade the other day and on cutting some old wood down I hit a bolt of some sort (very hard)

Didn't realise and kept pushing now the blade just barely cuts and no more.

Anything I can do to save it ?

cheers

allegdedly (according to an and bob phillips) you can resharpen a blade by using an abrasive disc on a sander and just touching the top of each tooth (with the saw off and rotating by hand obviously)

however for your degree of damage you probably need a saw doctor and it might work out cheaper just to replace the blade.

if you are going to do a lot of wood recycling you also ough to invest in a metal finder as bolts, screws, etc are a common occurence ( ive found rifle bullets, musket balls and allsorts in recycled oak beams)

I think the bin.

I did try the dremel and a disc but no good.

I suspect the bolt might have been high tensile steel...an M42 blade (if that's what you're using) would probably struggle with that but I understand they cope very well with ordinary steel ie: nails - Rob

I think the best thing you can do to that,
is to cut it up and make a few thousand chatter tool tips :? :shock: :roll: :lol: :lol: :lol:
