C-Thru Compass and Protractor Set

C-Thru's Compass and Protractor Set includes two measuring tools in one pack.

Draw precise circles with the precision metal compass. It has a spring-bow head and the center wheel has a nickel finish that resists rust. The maximum circle diameter on the compass is approximately 10.375", while the compass's length is 6". The compass includes one piece of drafting lead and an eraser.

Calculate angles easily and accurately with the half circle protractor, which is graduated in degrees. It lays flat and increments are clearly printed in black. The protractor's straight segment offers a straight edge ruler with inches on the outside, and centimeters on the inside.
