Century Drill Tool Co Inc 95111 Plug Tap 1/2-13 Nc

Product Description

The CENTURY DRILL TOOL CO INC 95111 is a 1/2-13 NC plug-style fractional tap designed for hand cutting applications in metal, plastic, and similar materials. The 1/2-13 designation refers to a 1/2-inch diameter with 13 threads per inch in the National Coarse (NC) thread standard. Threads are precision cut and accurately formed to produce consistent, exact threading with each use. The tap is heat treated and tempered to achieve hard, durable cutting edges that extend service life across repeated threading operations. This tool is suited for trade professionals and skilled tradespeople who require reliable thread-forming performance in repair, fabrication, or maintenance work.

This plug tap is appropriate for hand threading applications where a starting taper tap has already been used or where through-holes and blind holes with adequate depth are involved. The plug style sits between a taper tap and a bottoming tap in the standard tap sequence, making it a versatile choice for general-purpose threading tasks in field and shop environments. Sold as a package of 2 units, it provides a ready spare for jobsite or shop inventory.

Key Features

• 1/2-13 NC thread specification for standard National Coarse applications

• Precision-cut, accurately formed threads for consistent thread quality
• Heat treated and tempered construction for hard cutting edges and extended service life
• Designed for hand cutting applications
• Package includes 2 taps per unit

Compatibility

Designed as a standard 1/2-13 NC plug tap suitable for hand threading operations in materials commonly encountered in mechanical, plumbing, HVAC, and general fabrication trades.

Installation Notes

This tap is intended for hand cutting use with a standard tap wrench. Apply cutting fluid appropriate to the workpiece material to reduce friction and extend tap life. Ensure the workpiece is securely clamped before beginning threading. Back off periodically during threading to break chips and prevent tap binding or breakage.
