Century Drill Tool Co Inc 93201 Npt Tap Drill Bit 1/8-27

Product Description

The CENTURY DRILL TOOL CO INC 93201 is a combo pack that includes a 1/8-27 NPT hand tap and a 21/64 inch drill bit, packaged together for internal pipe thread cutting. The tap is heat treated and tempered to file-hard standards, delivering consistent thread form and extended service life. The set is designed for hand cutting applications, making it a practical two-piece solution for plumbers, pipefitters, and maintenance technicians who need to cut NPT threads directly in the field or at the bench. Each pack contains 2 pieces.

This tap and drill combo is suited for internal threading on all types of pipes using the 1/8-27 NPT standard. The drill bit prepares the correct pilot hole, and the tap follows to cut precise national pipe threads. This size is commonly used in plumbing, HVAC, and light industrial applications where 1/8-inch pipe fittings and ports are required. The hand-tap design makes it appropriate for low-speed, manually controlled operations where a drill press or tapping machine is not available.

Installation Notes

This tool is typically used by plumbers, pipefitters, and HVAC technicians for field or bench tapping operations. Always de-energize and depressurize the system before working on any pipe or fitting. Use appropriate cutting fluid to reduce friction and extend tap life. Apply steady, even hand pressure and back the tap out periodically to clear chips and prevent binding.
