The CENTURY DRILL TOOL CO INC 95005 is an 8-32 national coarse (NC) plug-style machine screw tap used to cut internal threads in metal, plastic, and similar materials. Sold in a 2-pack, this tap features precision-cut, accurately formed threads designed to produce consistent, exact threading on every pass. The tool is heat treated and tempered for hardened thread-cutting surfaces, extending service life through repeated use. It is designed for hand cutting applications, making it a practical choice for maintenance techs, electricians, plumbers, and HVAC technicians who need to chase or cut 8-32 threads in the field or shop.
This tap is suited for light-duty threading tasks common in trade work, including tapping holes for machine screws in electrical enclosures, equipment panels, HVAC components, and plumbing fixtures. The 8-32 NC thread size is one of the most widely used machine screw sizes in equipment assembly and repair, making this tap a useful addition to any service technician's toolkit. The plug chamfer style is the standard starting point for most through-hole and blind-hole tapping operations.
Designed as a standard 8-32 NC plug tap for use in any application requiring hand-cut machine screw threads in that size and thread pitch.
A licensed or experienced tradesperson should select the correct drill bit size for the pilot hole before tapping — an undersized or oversized pilot hole will damage the tap or produce weak threads. Secure the workpiece firmly before tapping, apply cutting fluid where appropriate for the material, and turn the tap handle with steady, even pressure, backing off periodically to clear chips. Do not force the tap if resistance increases sharply, as breakage in a blind hole can require extraction tools to correct.
