The CENTURY DRILL TOOL CO INC 95305 is a two-piece combo pack pairing an 8-32 national coarse plug-style machine screw tap with a No. 29 drill bit. The tap features precision-cut threads accurately formed for consistent, repeatable threading in metal and other machinable materials. Both the tap and bit are heat treated and tempered to produce hard, durable cutting edges that hold up over extended use. This combo is designed specifically for hand cutting applications, making it a practical grab-and-go pairing for tradespeople who thread fastener holes in the field or shop.
The 8-32 thread designation is a standard coarse machine screw size used across HVAC equipment panels, electrical enclosures, junction boxes, and light structural assemblies. The included No. 29 drill bit is the correct tap-drill size for 8-32 threads, eliminating the need to source the matching bit separately. Suitable for use in steel, aluminum, brass, and similar materials in residential and light commercial trade work where hand tapping is the preferred or required method.
Designed for hand tapping 8-32 national coarse machine screw threads in machinable materials including steel, aluminum, and brass.
Hand tapping should be performed with an appropriate tap wrench; power driving this tap is not recommended for hand-cutting-rated tooling. Secure the workpiece firmly before drilling the pilot hole with the No. 29 bit, then advance the tap gradually, backing off periodically to clear chips. Apply a suitable cutting fluid when tapping steel to reduce heat and extend tool life. Follow applicable shop safety practices including eye protection when drilling and tapping.
