Toolstation : Engineers Square

[transatlantic]

Just picked up 2 of these in different sizes and am very pleased with them for the price. Just though I'd share

According to DIN 875/1, from what I understand, the 200mm version should only have a maximum variation of 0.02mm

Looks a very good buy. Less than a third of the price of the Kinex ones at Workshop Heaven made to the same standard. Thanks for posting, I may pick up a 200mm one.

If anybody is in the market for engineer's squares, I can heartily recommend having at least one of 3" (75mm) size. Small, nimble and light; just right for all sorts of jobs like joint marking, checking squareness and camber of plane blades during grinding, and getting into places bigger squares won't go (inside small boxes to check for square when gluing up, for example). They're not expensive, either.

 

[Wizard9999]

I have the 75x50mm and 150x100mm Kinex ones, thought if I bought the 200mm from Toolstation it would bring the average cost of the three down :lol: . Honestly, there's a logic there somewhere.

Tool station is the best! So cheap

 

[tomlt]

Maybe I was unlucky, but I ordered all 3 of these from toolstation a little while back, they're "ok" but not toolroom quality, one of mine was actually quite off - probably 2mm from square at 150mm or so, so I wasn't overly impressed.

I think they're usually Silverline, so they're cheap for a reason.

I think a high percentage of engineer's squares that cheap are likely to be inaccurate.

I hope you got your money back, that's terrible.

How can that be if they claim it is made to a standard, or is somebody being a bit clever with some wording somewhere?

I seem to remember reading that woodworking squares are only accurate on the face and one edge, can't recall whether it is inner or outer edge. Engineers' squares are accurate on both edges. I wonder why?

I have learned to run the other way whenever I see the word Silverline

 

[Rorschach]

An actual set of certified squares is not very expensive I think mine were under £30 for 4 different sizes. They are all perfectly square and more than good enough for my engineering skills.

 

[woodenstx]

I picked up the short and long "engineers squares" from TS.... utter dog turd The small one seems just about fine but the longer one is out by a moderate margin (and also appears to have a curve in the outer edge). Yes I should take them back but apatrhy and low cost means I cant be bothered. Also I got an incra uber measure for christmas so that should sot my measuring out, and for cabinetry I use the old measure approach

 

[transatlantic]

Maybe I was just lucky then.

 

[woodenstx]

I guess it depends on the handling post production line/QA... also Standards are never standard :lol:

 

[DTR]

How can that be if they claim it is made to a standard, or is somebody being a bit clever with some wording somewhere?

Terry.

The standard can only reasonably apply at the point of manufacture. If the blade and stock are not rigidly joined (sloppy rivets etc) then it wouldn't take much to knock it out of square after the QC has been carried out. I can't account for a warped blade though.

 

[lurker]

Standards have tolerances.
That din standard quoted will be the b grade and the square is most likely just in tolerance

You need to realise standards are dominated by manufacturers and really mean what's the worst we can get away with.

I speak as an ex bsi committee member writing standards

 

[novocaine]

simple answer is they are manufactured to the standard, not certified to the standards.

din 875/1 requires 0.014mm deviation for 150mm to be class 2 (lowest class), so anything with visible deviation at the tip is definitely out of spec.

+1. Silverline stuff is usually pretty poor quality.

and run quickly!

I had a silverline engineers vice with 4" jaws. Tightening up one day the movable jaw casting snapped in two! With just my hand pressure!
The piece being held fell out and I was lucky to escape injury.
Never again for that make.
