Abstract

PURPOSE:To provide boring with a drill having the extremely small diameter and high positional accuracy by covering at least one side surface of hard synthetic resin plate-like workpiece such as printed circuit substrate wit an auxiliary plate made of resin composition. CONSTITUTION:Auxiliary plate 2, 3 for boring and cutting cover at least one side surface of a hard synthetic resin plate-like workpiece (printed circuit substrate) 1. In boring and cutting the workpiece 1, boring auxiliary plates 2, 3 for protecting the workpiece 1 are made of resin composition consisting of 100pts.wt. of polyolefin, 50-200pts.wt. of pulverulent organic filler and 10-100 pts.wt. of pulverulent inorganic filler. These auxiliary plates 2, 3 are relatively soft and excellent in cushion property. Thus, the printed circuit substrate 1 or the like can be extremely smoothly bored. Even if the diameter of a drill is very small as 0.1-0.3mm for example, said substrate can be bored with high accuracy.
