Value Collection 314-9581 Tap Drill Set 18 Piece Hss

Product Description

The VALUE COLLECTION 314-9581 is an 18-piece tap and drill set designed for threading operations across a range of standard inch sizes. The set covers tap thread sizes from 6-32 up to 1/2-13 and includes matching drill bits sized from 5/16 inches to 27/64 inches. All taps and drills are manufactured from high speed steel with a bright finish. Taps feature a plug chamfer, making them suitable for through-holes and moderately deep blind holes. The set ships in a metal case for organized storage and field use. Machinists, millwrights, plumbers, and HVAC technicians reach for sets like this when cutting new threads in metal components during repair or fabrication work.

This set is suited for general metalworking, maintenance, and repair applications in residential and commercial trade environments. It covers the most common unified coarse and unified fine thread sizes encountered in mechanical, HVAC, plumbing, and electrical panel work. The metal case keeps taps and drills paired by size, reducing setup time on the job. The full range of tap sizes included — 6-32, 8-32, 10-24, 10-32, 1/4-20, 5/16-18, 3/8-16, 7/16-14, and 1/2-13 — addresses the majority of fastener thread profiles found in standard trade work.

Installation Notes

Tap and drill sets of this type are used by machinists, plumbers, HVAC technicians, and electricians when cutting or chasing threads in metal. Always use appropriate cutting fluid when tapping ferrous metals to extend tap life and reduce breakage risk. Secure workpieces firmly before drilling and align the tap perpendicular to the work surface to avoid tap breakage. Inspect each tap for wear or damage before use and replace any tap that shows signs of chipping or galling.
