Series
V-Blocks and Clamps
No. 278 Series 1" (25 mm) Capacity
Starrett No. 278 V-Blocks are precision ground to extreme accuracy. The
V's are central, parallel, and square with the ends and sides.
The blocks are made of steel, hardened and ground
and numbered in series so that the V's in each set are always in alignment.
The blocks have a 1/4-20 tapped hole through the sides so that they may
be attached to an angle iron. The angle iron holding the block can then
be attached to a lathe faceplate or held by a magnetic chuck.
Each block is 1 1/4" (32 mm) square and 1 5/8"
(40 mm) long.
