Straight Edges

VERITAS Straight Edge made of steel

Shop accuracy begins with a benchmark straight edge as a surface reference. These Canadian-made precision steel straight edges are ground flat to within 0.001 inch (0.025 mm) over the entire length on both edges, and have been stress-relieved to remain true under temperature variation. Useful for checking whether surfaces are flat or straight, they are 1-1/2 inch (38 mm) wide and easily stand on edge unsupported, leaving both hands free for precise measurement or tool adjustment. All have hang holes, allowing storage on a nail or hook. Not stainless!

VERITAS Straight Edge made of aluminium

A straight edge is extremely useful for setting up machines such as planers and jointers. The Veritas anodized aluminum straight edges are wide enough to stand on edge unsupported, so you have both hands free to make precise adjustments to your tools. Each also has a hanging hole for easy storage.

These aluminum straight edges are 1-3/4 inch (44.5 mm) wide and 7/16 inch (11 mm) thick, and will not rust. The reference edge is machined flat to within 0.003 inch (0.076 mm) over the entire length. They are available in three lengths, 24 inch, 38 inch and 50 inch (610 mm, 965 mm, 1270 mm). The 24 inch straight edge weighs 1 lb (450 g), the 38 inch weighs just under 2 lb (900 g), and the 50 inch version weighs 2.5 lb (1150 g).

STARRETT Steel Straight Edge

These straight edges are precision ground and nicely finished to rigid Starrett standards. They are unexcelled for drawing or scribing straight lines and checking surfaces for straightness. Their thickness and design permit them to retain shape and accuracy, but still be portable and easy to handle. Starrett No. 380 Series are not beveled or graduated. Not stainless!

Many jobs involve the use of straight edges in the flat position - and it is in this position that Starrett checks most stringently.

PREISSER Precision Straight Edge - with Bevel Edge

Straight edges are used to check if a surface is flat and straight. This one from Preisser is made of a special, hardened, steel alloy, and tapers to a point at one end. The edge is slightly rounded off, to help keep it from getting damaged, and to prevent it from cutting or marring the surface one wants to check. The straight edge is burnished to be glare-free and to avoid reflections but not stainless.

To use, the measuring edge is set on the surface to be examined. With back light, even the slightest gap or unevenness can be seen. Under favorable lighting conditions, one can detect a gap smaller than 1/100th of a millimetre.

Preisser manufacturers the straight edge to the DIN 874 GG-00 standard (German industrial standard), which works out to be 3/1000 of a millimetre. The back of the straight edge is covered with a strip of ridged plastic to provide a secure grip on the delicate instrument and to protect the hands in cold weather. The straight edge comes with a vinyl case. Picture: the 150 mm long straight edge.

MATSUI Precision Straight Edge

Straight edges from MATSUI made of rustproof stainless steel are carefully finished precision intruments. One edge is bevelled, but left with flat edge (0.8 mm for 400 mm and 1 mm for 600 mm version) which serves as measuring edge. These instruments are also supplied as a notched variant, with the notch in the bevelled edge. This lets you check surfaces that are interrupted by a sharp protruding object such as a plane iron. Supplied in a plastic sheath.
