Value Collection 314-9582 Tap Drill Set 18 Piece Hss

Product Description

The VALUE COLLECTION 314-9582 is an 18-piece tap drill set designed for standard hand tapping operations across a range of unified inch thread sizes. Built from high speed steel with a bright finish, both the taps and drills are suited for general-purpose metalworking, maintenance, and repair tasks. The set covers tap sizes from 6-40 up to 1/2-20 and includes drill sizes spanning wire, letter, and fractional inch formats. A plug chamfer on the taps makes them well suited for through-hole applications. Machinists, maintenance technicians, and tool room professionals will find this set a practical bench resource for common threading jobs.

This tap drill set is used in machine shops, maintenance facilities, and fabrication environments where a broad range of small-to-mid inch thread sizes must be cut or chased. The included drill sizes cover wire gauges 33 and 29, 25, 21, and 3, letter sizes I and Q, and fractional sizes 25/64 inch and 29/64 inch, giving the user the correct pilot hole drill for each tap in the set. The metal case keeps components organized and protected between uses. It is appropriate for use in ferrous and non-ferrous materials with compatible cutting fluids.

Installation Notes

Tap drill sets of this type are used by machinists and maintenance technicians working on threaded hole creation or repair. Select the matching pilot drill for the intended tap size before beginning, and use an appropriate cutting fluid for the workpiece material. Secure the workpiece fully before drilling or tapping to prevent movement. Inspect tap flutes for chips and clear them regularly during the tapping process to avoid tap breakage.
