No. It is sold undrilled, without finger holes, so it can be fitted to your hand and span at your pro shop. It ships polished for the most length, and your pro shop can take the surface down for an earlier, stronger read when the oil increases. Because the core is asymmetric, layout changes the reaction more than on a symmetric ball.
