Starrett C33-1224 Forged, Hardened Steel Center Head For Combina

Description

The Starrett C33-1224 Center Head, made of forged hardened steel with
a smooth black enamel finish, attaches to combination squares,
combination sets, and bevel protractors to accurately locate the center
of cylindrical or square workpieces. It fits blades 12″, 18″, 24″,
300mm, 600mm, or longer on Starrett combination squares (except the 33J
series and 8 series), combination sets, and bevel protractors

Protractors are tools that measure specific angles, which allow users to
create and replicate desired angles. The tools include a stationary
base and movable rule, usually connected by a scale that may be digital
or manual. They are useful in a wide range of applications, such as
measuring crown molding and installing baseboards. A protractor can be
included as part of a combination set, along with a center and a square.
A center accurately locates the center of a circle or cylindrical rod. A
square is used to scribe right angles and parallel lines, calibrate
miter and table saws, or as a miter, height gauge, or depth gauge.
