Precision biscuits are made from pressed solid beech to a very high standard and hold their tolerance. The biscuits are slightly compressed in manufacturing, so that on contact with the glue they expand tightly into the joint. Standard sizes are: No. 0 - 47 x 15 x 4mm, No. 10 - 53 x 19 x 4mm and No. 20 - 56 x 23 x 4mm.
