PAGE 51 — COMMON RADIUS DIAL INDICATOR CONTACT POINT
PROFESSIONAL REPAIRS & SALES IN THE U.S.A. SINCE 1959
Radius points are the most common and can be the cheapest of the indicator contact points. The diameter (ØA) is .188" and the radius is 4 mm. There are two styles: they're made of blackened, hardened steel or they have a carbide end, both with a light radius. Although they are available in many different lengths, we think it's best to buy the standard 1/4" length, and then combine it with an appropriate extension.
