Century Drill Tool 95410 7/16-20 Tap 25/64 Bit Combo 2pc

Product Description

The CENTURY DRILL TOOL CO INC 95410 is a two-piece combo pack that includes a 7/16-20 national fine thread tap and a matching 25/64-inch fractional drill bit. The tap features precision-cut threads accurately formed for consistent, exact threading results on every pass. Both tools are heat treated and tempered to achieve file-hard thread surfaces, which extends service life under repeated use. This combo is designed specifically for hand cutting applications, making it a practical choice for plumbers, HVAC technicians, electricians, and general trade professionals who need matched tap-and-drill sets for field or shop threading work.

This combo pack is suited for hand tapping operations where a 7/16-20 national fine thread is required. The 25/64-inch drill bit is sized to produce the correct pilot hole for the 7/16-20 tap, eliminating the guesswork of selecting a separate drill size. Typical applications include threading metal fastener holes, repair work on existing threaded connections, and new thread creation in ferrous and light non-ferrous materials during mechanical assembly or service tasks.

Compatibility

Designed for hand tapping applications requiring a 7/16-20 national fine thread; the included 25/64-inch drill bit is the standard pilot size for this thread specification.

Installation Notes

This tap and drill bit set is intended for hand cutting use only; do not use the tap in a power driver or drill press at high speed, as this can break the tap or damage threads. Secure the workpiece firmly before drilling the pilot hole and apply appropriate cutting fluid to both the drill bit and tap to reduce heat and extend tool life. Follow applicable trade codes and safe tool-handling practices when threading in confined or overhead locations.
