Three Point Surface Plates

APPLICATIONS Three point surface plates provide a precise reference surface for toolmaking, layout, or checking the accuracy of other surfaces. The three point bearing pads and rigid ribbed construction permit support by less accurate surfaces without disturbing the surface accuracy. Wooden cover supplied with each plate.

TOLERANCES Available precision ground flat within .0005" or hand scraped flat within .0002" through 12 x 18. On larger sizes, precision ground flat within .001" or hand scraped flat within .0005".

OPTIONS Wheeled and stationary stands are available to provide a working height of approximately 36" for plates 18" x 24" and larger. *Steel handles also available. Part Number is for one handle. Order Two.
