reb78 Posted July 22, 2015 Share Posted July 22, 2015 I use the hacksaw for metal. I have some old blades that my grandfather would have got when he worked for British Gas 30 years ago and they are great - will cut anything. However, my stock is running low. I bought some new ones recently (from Wickes i think) and they may as well have been made of butter. Absolutely useless and the teeth gone after very little use. Can anyone recommend some good ones for metal? Quote Link to comment Share on other sites More sharing options...

reb78 Posted July 22, 2015 Author Share Posted July 22, 2015 Sandvik blades every time for me. Thanks - they actually look like the ones grandad had - my remaining ones are so old that the lettering has worn off but the colouring is what i remember them looking like!

ejparrott Posted July 22, 2015 Share Posted July 22, 2015 I usually use Eclipse, but I certainly don't buy from Wickes!! Your local engineering hardware store should be able to sell you good quality blades. Quote Link to comment Share on other sites More sharing options...

landroversforever Posted July 22, 2015 Share Posted July 22, 2015 Decent branded stuff is always best. In no particular order.... Sandvik, Irwin, bahco, eclipse. Quote Link to comment Share on other sites More sharing options...
miketomcat Posted July 22, 2015 Share Posted July 22, 2015 Starret all the way nothing cuts or lasts as well in my opinion eclipse are useless. Mike Quote Link to comment Share on other sites More sharing options...
De Ranged Posted July 22, 2015 Share Posted July 22, 2015 Bahco or a local brand called Evercut One thing I will say is stay away from those expensive "unbrakeable flexy" blades they come under a few different names.... and yes they really do cut stuff you would normally snap your blade trying to cut..... catch is so long as you don't mind the cut going where it wants. I destroyed a hacksaw frame trying to tension the blade to stop it wandering lol in the end biffed the remaining blades in the scrap bin Oh and get your tooth count right for the thickness your cutting... think it was a min of 4 teeth must contact the metal while you cut (google it, been a while since I learned all that lol) this will be why your teeth are snapping too few a teeth in contact with the work 1 Quote Link to comment Share on other sites More sharing options...

vulcan bomber Posted July 22, 2015 Share Posted July 22, 2015 3 teeth in contact at all times with saw blades. The Bacho blades at work seem ok, something that's hard to teach with hacksaws is they only cut on the forward stroke. Quote Link to comment Share on other sites More sharing options...
reb78 Posted July 22, 2015 Author Share Posted July 22, 2015 Is the teeth in contact thing to do with the thickness of the material? So a 3mm thick (~0.12") piece would need a blade with ~25tpi (closest available would be 24tpi)? If that's correct, wouldn't 1mm thickness technically require 75tpi? When using decent blades, you can feel them cutting on the forward stroke. They dont do much on the backward one, so its easier to release the pressure when drawing back.

miketomcat Posted July 22, 2015 Share Posted July 22, 2015 I've always used 18tpi on aluminum, 24tpi on steel and 32tpi on stainless. As for the 3 teeth thing this is achieved by angling the cut ie thick metal cut be cut at 90° where as thin needs 45° or more. But that's just what I was taught I maybe wrong but it works for me.

ejparrott Posted July 22, 2015 Share Posted July 22, 2015 Angle the cut Richard. You should never try to cut anything thin by going across it directly, always lengthen the cut and cut at an angle. Wondered yesterday why my hacksaw wasn't cutting very well when I know it's not all that long since I changed the blade.....then I remembered...lent it to a neighbor a few weeks ago...blade was in backwards...no wonder it wouldn't cut.....

ballcock Posted July 23, 2015 Share Posted July 23, 2015 Having the blade in backwards can be a benefit at times. Pull saws have their uses, if you are cutting a finished surface from the rear face then reversing the blade will give a cleaner cut and on some cheaper frames pulling the blade will keep it taught where as pushing will flex the frame causing the blade to loosen.

reb78 Posted July 24, 2015 Author Share Posted July 24, 2015 Thanks all. Screwfix have Irwin ones in stock, so I will pick up a few of these at the weekend. Looking at the pictures of the ones on the toolstation website (essentially wickes), these were the blue coloured ones I bought from wickes once before that appeared to be made of chocolate. They were actually eclipse blades! Quote Link to comment Share on other sites More sharing options...
nickwilliams Posted July 24, 2015 Share Posted July 24, 2015 If you generally wear your hacksaw blades out rather then snap them then by far the best blades to use are 'all hard' HSS blades made by LS Starrett. If you normally break the blade before you wear it out then bimetal blades from Sandvik are a better bet. It's important to keep a range of tooth pitches in stock for use on different materials and thicknesses. 1 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 24, 2015 Share Posted July 24, 2015 So what you're saying , is cos I prefer Sandvik blades, that I am a bit cack-handed with them Probably true to be fair Quote Link to comment Share on other sites More sharing options...
miketomcat Posted July 24, 2015 Share Posted July 24, 2015 So what you're saying , is cos I prefer Sandvik blades, that I am a bit cack-handed with them Probably true to be fair What's more worrying is it's saying I'm not cack-handed which I most definitely am.

smallfry Posted July 24, 2015 Share Posted July 24, 2015 Starret all the way nothing cuts or lasts as well in my opinion eclipse are useless. Mike What he said ^ And FYI you are incorrect. Wickes hacksaw blades are NOT made of butter, or chocolate. But cheese. Camenbert I believe. Quote Link to comment Share on other sites More sharing options...
reb78 Posted July 25, 2015 Author Share Posted July 25, 2015 Well, got a couple of Irwin blades this morning. Fitted the 18tpi one to cut some 3mm RHS. What a difference to my old blade!!! Like a knife through butter! Quote Link to comment Share on other sites More sharing options...
