Drill sizes shown are recommendations only and PowerCoil would strongly suggest 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 those of 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 our website – www.powercoil.com.au.

IMPORTANT The success of any drill and tapping operation is dependant upon many factors –type of material being cut, cutting speed, coolant,equipment<br />
being used – and it is not possible to give specific drill sizes for each material. Drill sizes shown are re<strong>com</strong>mendations only and PowerCoil would strongly<br />
suggest that independent testing be performed for specific and critical applications.<br />
When using <strong>wire</strong> <strong>thread</strong> <strong>insert</strong>s it is important that the drilling and tapping diameters and lengths listed below are adhered to.<br />
The figures outlined in these tables en<strong>com</strong>pass effective free coil tolerances for most globally recognized standards and manufacturers, including those<br />
of reduced diameter <strong>wire</strong> <strong>thread</strong> <strong>insert</strong>s.<br />
PowerCoil <strong>wire</strong> <strong>thread</strong> <strong>insert</strong>s can be manufactured to different standards upon request. Technical data on these standards can be obtained from our<br />
website – www.<strong>powercoil</strong>.<strong>com</strong>.<strong>au</strong>.<br />

Optimum Thread<br />
performance with<br />
Wire Thread Inserts<br />
is achieved when<br />
the <strong>insert</strong>s are<br />
installed 1/2 to 1<br />
pitch below the<br />
surface of the<br />
Tapped Hole. This<br />
means that the<br />
actual length of an<br />
installed <strong>insert</strong> is<br />
equal to dimension<br />
DL less 1/2 to 1<br />
pitch. Dimensions<br />
AL and CL allow for<br />
tap end clearance<br />
of finishing Taps.<br />
When using<br />
Bottoming and<br />
Spiral Flute Taps<br />
these dimensions<br />
maybe reduced by<br />
an amount equal to<br />
2 <strong>thread</strong> pitches.<br />
Any counterbore<br />
depths must be<br />
added to these<br />
dimensions.<br />
