Value Collection DT22HEX-SET-NC5 Drill Tap Set 5pc Unc

Product Description

The VALUE COLLECTION DT22HEX-SET-NC5 is a 5-piece combination drill and tap set designed for threading operations in metal and other hard materials. Each tool in the set combines a drill point and tap geometry into a single shank, allowing the user to drill and tap a hole in one operation. The set covers a thread range from 1/4-20 to 1/2-13 UNC and is manufactured from high-speed steel for durability under load and heat. This set is a common shop and field tool for machinists, millwrights, and maintenance technicians who need to cut UNC threads efficiently without tool changes.

This combination drill and tap set is suited for use in maintenance, repair, and fabrication environments where UNC threaded holes are required across a range of fastener sizes. The 1/4-20 through 1/2-13 UNC range covers some of the most common fastener sizes found in mechanical assemblies, HVAC equipment mounting, electrical enclosures, and structural connections. The set is appropriate for use with a drill press or hand drill at appropriate speeds for the material being threaded.

Key Features

• Combination drill and tap design allows drilling and tapping in a single pass
• Covers 1/4-20 to 1/2-13 UNC thread range in one set
• High-speed steel construction provides resistance to heat and wear
• 5-piece set spans common UNC fastener sizes used in trade and industrial applications
• Reduces tool changes and speeds up threading operations in the field or shop

Compatibility

Designed as a general-purpose UNC combination drill and tap set compatible with standard drill press chucks and hand drills accepting straight-shank tooling. Suitable for use in steel, aluminum, and similar machinable materials within the 1/4-20 to 1/2-13 UNC thread range.

Installation Notes

Combination drill and tap tools should be used by machinists or experienced tradespeople familiar with cutting speeds and feeds for the material being threaded. Always secure the workpiece and use appropriate cutting fluid to extend tool life and improve thread quality. Do not exceed the recommended RPM for the tap size and material, as combination tools are more sensitive to breakage than standard drills. Inspect each tool for damage before use and replace any worn or chipped tools to avoid thread damage.
