Century Drill Tool Co Inc 95409 7/16-14 Tap Drill Bit Combo

Product Description

The CENTURY DRILL TOOL CO INC 95409 is a two-piece combo pack containing a 7/16-14 national coarse (NC) tap and a 3/8 inch fractional drill bit, designed for hand cutting thread applications in metal and similar materials. The tap features precision-cut threads that are accurately formed for consistent, exact threading results on each pass. Both the tap and bit are heat treated and tempered to achieve file-hard threads, extending service life under repeated use. This combo is suited for tradespeople and technicians who need a matched tap-and-drill pair for field repairs, equipment maintenance, or fabrication tasks.

This combo pack is intended for hand threading applications where a 7/16-14 NC thread is required. The 3/8 inch drill bit serves as the correct tap drill size to prepare the pilot hole before threading. Typical uses include threading bolt holes in HVAC brackets, plumbing supports, electrical enclosures, and general mechanical assemblies. The two-piece format keeps the correct drill-and-tap pairing together, reducing the chance of mismatched sizing on the job.

Installation Notes

This tap and drill bit combo is intended for use by mechanics, technicians, and tradespeople performing hand threading with a tap wrench. Before tapping, drill the pilot hole using the included 3/8 inch bit at the appropriate depth for the fastener being used. Apply cutting fluid during tapping to reduce friction and extend tap life. Back the tap out periodically to clear chips and prevent binding or breakage.
