Features By Drill Specifications

■ Diameter Tolerance

★ Advantages of Plus Tolerance
・ Drills can be used at a hole tolerance of about H9 without the need for a reamer.
・ When drilling pilot holes for deep holes, setting a hole diameter with a plus tolerance allows highly precise guide holes to be drilled.
・ Tapping costs can be reduced and the durability of taps can be improved by setting a hole diameter with a plus tolerance when drilling pilot holes for taps.
・ Hole diameter minus values following regrinding can be reduced and limited.
