Elongation Sets

Yong Yi’s elongation sets of die minimize deviation in diameter, then we sorted the finished dies to individual sets by tolerance. With the elongation sets, you can achieve the maximum speed of the machine and reduced diamond wear.

Typical Hole Sizes

for ND/SSCD dies

0.0004in to 0.078in

(0.010mm to 2.0mm)

for PCD dies

0.004in to 0 .12in
