Drill sizes shown are recommendations only and PowerCoil would stronglysuggest that independent testing be performed for specific and critical applications.When using wire thread inserts it is important that the drilling and tapping diameters and lengths listed below are adhered to.The figures outlined in these tables encompass effective free coil tolerances for most globally recognized standards and manufacturers, including thoseof reduced diameter wire thread inserts.PowerCoil wire thread inserts can be manufactured to different standards upon request. Technical data on these standards can be obtained from ourwebsite – www.powercoil.com.au.S (Drilling Length – min.) T (Tapping Length – min.)
