Cutting Off / Parting

Me again,

I lied.  

The holder is a William's No. 29-R Cutting-Off and Side Tool.

Hey Guys,

I have an Armstrong No. 29 Cutting Off Tool.  Can anyone out there tell me the correct blade size for this tool?  Can anyone out there suggest a location I can purchase one or two blades in that size?

Thanks as usual for all the help.

Greg

Hi There,

As far as I know, the 29 uses a 3/32" x 1/2" cut-off blade.  These
usually come about 4" to 4-1/2" long.  There are lots of them on eBay.

Good Luck!

Unfortunately, no go with 1/2-inch. When I measure the opening I get 0.445 to 0.486. Maybe 7/16-inch. Can’t find those anywhere.

That's an Armstrong.  As far as I can tell, the only difference is the locking mechanism.  Any guesses where one could acquire a 7/16-inch blade?

It's listed there, and clearly states 1/2-inch, but I've tried a 1/2-inch blade, but no go.

Guess I can try grinding a 1/2-inch blade down to fit, but that does not seem like a prudent approach.

Agreed, but 1/2-inch won't fit in the tool in front of me.  I need to believe the tool in hand over a Armstrong and Williams catalog.

Looking online I find no suppliers of 7/16" but lots of 1/2".  With the manufactures listing the product as using 1/2" also makes it seem as something is afoul here.

I have some original blades. They were not the regular rectangular kind that is mostly sold today. Armstrong and Williams made a tapered profile blade. If you look closely at the Williams catalogue extract you can see this.

John do your original 1/2" measure the full 1/2" or are they like my 5/8" a bit smaller?   If so what does the groove in your holder measure for height?

John,

I assume "not rectangular" implies wider at eh top of the blade than the bottom.  Could you check the dimensions of the blades you have?

Thanks,

Unfortunately, no go with 1/2-inch. When I measure the opening I get 0.445 to 0.486. Maybe 7/16-inch. Can’t find those anywhere.

Hi There,

As far as I know, the 29 uses a 3/32" x 1/2" cut-off blade.  These
usually come about 4" to 4-1/2" long.  There are lots of them on eBay.

Good Luck!

I’ll run the measuring equipment over them and let you know.

John,

 

I assume "not rectangular" implies wider at eh top of the blade than the bottom.  Could you check the dimensions of the blades you have?

 

Thanks,

 

Greg

John do your original 1/2" measure the full 1/2" or are they like my 5/8" a bit smaller?   If so what does the groove in your holder measure for height?

I have some original blades. They were not the regular rectangular kind that is mostly sold today. Armstrong and Williams made a tapered profile blade. If you look closely at the Williams catalogue extract you can see this.

I do not have any 1/2" cuttoff steel but a piece of Armstrong brand 5/8" I have only measures 0.59 not 0.625.

Looking online I find no suppliers of 7/16" but lots of 1/2".  With the manufactures listing the product as using 1/2" also makes it seem as something is afoul here.

Agreed, but 1/2-inch won't fit in the tool in front of me.  I need to believe the tool in hand over a Armstrong and Williams catalog.

OK I’m back.

I have an Armstrong No.20 tool and an Armstrong ½ inch blade.

Too hard to escribe the blade profile so I took pic – the blade in the No.20 tool has same profile.

Never tried to post a pic before so I hope it comes through.

 

The blade measure 12mm top to bottom, 2.25mm wide at the top and 1.55mm wide at the bottom.

Sorry if you likes inches but I find metric easier to use on the vernier.

The bottom is not flat but has a bevel to match the bevel in the tool holder. Likewise the top is only flat for about half the width then has a low bevel. This allows the blade to engage firmly with the cam lock on the tool.

Cheers

John B

Use a mill or file and widen the slot to 1/2'. That will make it a standard sze.
