How easy would it be to drill through a hacksaw blade?
Reason:
I have a hand B&Q mitre saw the blades (350mm) are now unavailable.
The nearest I can find are hacksaw blades, not ideal as saw is used for
wood.
However as I dont use it much it would do but I would need to re drill
the positioning holes.
I have emailed B&Q but dont expect an answer.
I have electric drill and normal metal/wood drills.

I'd have thought you need something like a burr (diamond or carbide or
something), but then you need something to mount it in. Electric drill
would need a very steady hand :-)

I'd buy a tungsten drill (Ebay) and give it a try. Tungsten are very
brittle so best used in a drill press.

My thoughts would be: good quality high carbon steel blades? Forget it.
Cheaper steel blades with case hardened teeth might take it though. If I
couldn't drill through after reasonable attempts I might try heating it
up to anneal it first then re-tempering it afterwards. But someone will
be along shortly to tell you why my recollection of GCE O-level

they are very hard (although some of the very cheap ones aren't.)

And some of the more expensive ones aren't either, in the part that needs
drilling: look for "bi-metal" blades. Flexible back but hard teeth -- so the
back part may be easier to drill with a standard metal bit. (ISTR it's done with
differential hardening).

it said they were on clearance at 10p each when I looked, but couldn;t
find any stores with them in stock, and unavailable for mail order.

several complete saws on gumtree, or bahco power saws seem to take a
350mm blade.

Heat the part you want to drill to red/orange heat and let it cool
naturally.

There are some tungsten tipped drills that pride themselves on being

Easy with a diamond core drill and lots of water. IME anything else is
a very iffy process.

I'd try a cheap carbide tile/glass drill bit like:

https://www.ironmongerydirect.co.uk/...-6x60mm-233607

But make sure that the saw blade is clamped firmly and if possible use a
drill stand or mill - if you haven't got one then you will need a very
steady hand and take great care as the bit will tend to slip across the
blade.

You might perhaps get away with just softening the ends. Since hacksaw
blades are relatively cheap, you could experiment a bit. I would say it
is not worth the effort to try to re-harden after drilling, you just
won't have the control.

Heat the first 5 mm or so up quickly to red heat and let it air cool.
This will probably soften an inch or so.

Stick to carbon steel blades, don't bother with the expense of high
speed steel (HSS). Don't bother to try to drill "single metal" blades
even with cobalt drills.

May still have an issue with the holes, the one I have slots in to a
larger hole then the neck of the bolt slides in to a smaller one.
So it has two holes adjoining like a figure of eight at each end.

Have you considered modifying the mitre saw to take hacksaw blades? It looks
pretty easy.

It will probably shatter when you try it as they are, I think made with a
hard outer surface, at least the ones that do not go blunt are.

It could be a brand that has been renamed by b/q to something else so what
you might be looking for is a different make.

(Are you sure the blades are unavailable? I assume you've checked eBay?)

IME hand mitre saw blades tend not to be hardened except for the teeth.
You can see a bluish colour to the teeth where they have been induction
heated to temper them.

Hacksaw blades can be flexible or all hard.
The flexible ones may be drillable but not the all hard without
softening them but then they would lose their edge quickly.

Hand saws are probably hardened throughout so they are springy and don't
bend easily. They will have been tempered to be softer than the teeth so
they don't shatter but will still be quite hard. The teeth will have had
a second hardening/tempering after the main blade which you can see by
the bluish colour.

Thanks all for contributions, I will probably go for cheap type hacksaw
blade and see how I get on.
Just thinking as I type a couple of years back I made some lock picks
from a hacksaw blade and I ground them and filed them rather easily,
must have been cheap blades.

Does not have to be extremely hard for lockpicks,Go to some car parts
place and you will find metal strips that come from window wiper blades
lying on the ground outside, these are good for lockpicks.
