Series
Double Squares with hardened blades
No. 13 Series 4-6"
No. 13M Series 100-150 mm
These squares are very popular with machinists, toolmakers, and patternmakers.
The sliding blades are adjustable making it more practical for a wide
variety of uses than a common square with fixed blade. The faces of the
head are ground square, and the 6" (150 mm) size has a level.
The bevel blade is available, featuring an
octagon angle 45° at one end and a hexagon angle 60° at the other
end, clearly marked.
A drill grinding blade, also available for
6" (150 mm) squares, is beveled to 59° for drill grinding on
one end and 41° (the cutting angle of countersinks for machine screws)
at the other. Both ends have quick-reading graduations in 64ths, and the
graduation is located to measure perpendicularly to the axis of the drill.
By reading the graduations, the center point can be easily and accurately
located.
The 6" square head used with the drill
grinding blade is approximately 3 1/2" (90 mm) long, and the faces
approximately 9/16" (14 mm) wide.
