Century 95309 14-20 Tap Drill Bit Combo 2 Pack

Product Description

The CENTURY DRILL TOOL CO INC 95309 is a 14-20 national standard plug-style machine screw tap paired with a number 10 drill bit in a two-piece combo pack. The tap features precision-cut threads accurately formed for consistent, exact threading results on each use. Both the tap and bit are heat treated and tempered to produce hard, durable cutting edges that extend working life across repeated use cycles. This combo is designed for hand cutting applications and is well suited for trade and maintenance professionals who need a matched tap-and-drill set for 14-20 thread work.

This combo pack is intended for hand-tapping applications where a 14-20 machine screw thread is required. The plug-style tap geometry makes it appropriate for through-hole threading tasks common in light mechanical assembly, equipment maintenance, and repair work. Technicians in HVAC, plumbing, electrical, and general mechanical trades will find this set useful for field tapping tasks where a pre-matched drill and tap combination saves setup time and reduces the risk of mismatched sizing.

Compatibility

Designed as a matched tap-and-drill combo for hand-tapping 14-20 machine screw threads in through-hole applications across general mechanical and trade repair work.

Installation Notes

This tap set is intended for hand cutting use and should be used with an appropriate tap wrench rather than power tools to avoid tap breakage. Secure the workpiece firmly before beginning, and apply cutting oil to the tap during threading to reduce friction and extend tap life. Back the tap out periodically to clear chips and prevent binding. Follow applicable shop safety practices when working with cutting tools.
