KEY POINTS
•
Bi-Metal™ construction synergises the self-drilling performance of
a AISI C1022 carbon steel self-drilling point with the exceptional
corrosion resistance of an AISI 316 austenitic stainless steel body
and head.
•
Revolutionary SuperTEK® double-helical point consistently provides
industry-leading drilling performance due to its aggressive rake and
flank angling and honed blade-edge.
•
This product will self-drill and self-tap in mild steels from 4.0 mm
to 22.0 mm in overall thickness.
•
A4-50 (EN 1.4401/ AISI 316) stainless steel body and head provide
ultimate corrosion protection that exceeds organic coating performance.
