Century Drill Tool 97508 5.0x0.80 Metric Tap Drill Combo

Product Description

The CENTURY DRILL TOOL CO INC 97508 is a metric plug-style tap and number drill bit combo pack designed for hand cutting thread applications. The set includes a 5.0 x 0.80 mm metric tap paired with a number 19 drill bit, giving technicians and tradespeople both the clearing and threading tools needed in a single package. Threads are precision cut and accurately formed for consistent, repeatable results. The tap is heat treated and tempered to file-hard condition, extending service life and reducing wear during repeated use in metal threading tasks.

This combo pack is suited for hand tapping operations in metal fabrication, equipment repair, and maintenance work across HVAC, plumbing, electrical, and general mechanical trades. The plug-style tap is the standard choice for threading through-holes and initiating threads in blind holes when used in sequence with a bottoming tap. The included number 19 drill bit is sized to produce the correct tap drill diameter for the 5.0 x 0.80 mm thread profile, eliminating the need to separately source a matching bit.

Installation Notes

This tap and drill bit set is intended for hand cutting use and should be operated with a standard tap wrench rather than power equipment to avoid overloading the tap. Always secure the workpiece before drilling and tapping. Apply appropriate cutting fluid to extend tap life and improve thread quality, particularly in ferrous metals. Follow standard shop safety practices and use eye protection when drilling and tapping.
