Century Drill Tool 97509 Metric Tap Drill Bit 5.0x0.90

Product Description

The CENTURY DRILL TOOL CO INC 97509 is a metric plug-style tap and drill bit combo pack designed for hand cutting threaded holes in metal and similar materials. The set pairs a 5.0 x 0.90 metric tap with a number 20 drill bit, giving technicians both tools needed to drill and tap in a single package. Threads are precision cut and accurately formed for consistent, exact threading results. The tap is heat treated and tempered to file-hard hardness, extending service life under repeated use. This two-piece combo is suited for mechanics, maintenance trades, and fabrication work where metric threading is required.

This combo pack is intended for hand tapping applications where a 5.0 mm diameter thread with a 0.90 mm pitch is required. Common use cases include threading bolt holes in light fabrication, equipment repair, and maintenance tasks across HVAC, plumbing, and general mechanical service work. The plug-style tap geometry is appropriate for through-holes and partially blind holes. The included number 20 drill bit is sized to produce the correct tap drill diameter for the M5 x 0.90 thread form.

Installation Notes

This tap and drill set is intended for use by mechanics and trade professionals performing hand tapping operations. Before tapping, secure the workpiece firmly and use the included drill bit to produce the correct pilot hole. Apply appropriate cutting fluid to the tap before threading to reduce friction and extend tool life. Do not use this tap in a power driver or drill press without a dedicated tapping attachment, as off-axis force can break the tap.
