Century Drill Tool 97519 M12x1.25 Tap 27/64 Drill Bit Set

Product Description

The CENTURY DRILL TOOL CO INC 97519 is a two-piece combo pack pairing an M12 x 1.25 metric plug-style tap with a 27/64 inch fractional drill bit. Threads are precision cut and accurately formed for consistent, exact threading in hand-cutting applications. The tap and bit are heat treated and tempered to achieve file-hard threads, extending service life in regular trade use. This combo is well-suited for machinists, maintenance technicians, and general fabrication tradespeople who need a matched tap and drill set for a single metric thread specification.

This set is intended for hand tapping operations where M12 x 1.25 fine-pitch metric threads are required. The plug-style tap is the standard choice for through-hole threading and for continuing threads in a partially tapped hole. The included 27/64 inch drill bit is sized to produce the correct tap drill diameter before threading. Typical applications include threading metal components in mechanical, HVAC, plumbing support structures, and general industrial maintenance work.

Installation Notes

This set is used by machinists, maintenance technicians, and tradespeople performing manual threading operations. Always secure the workpiece firmly before drilling and tapping. Use appropriate cutting fluid to reduce heat and extend tap life when threading steel or other hard metals. Ensure the tap is kept perpendicular to the work surface to avoid cross-threading or tap breakage.
