Value Collection 00574194 Drill Tap 8-32 Unc H3 Hss

Product Description

The VALUE COLLECTION 00574194 is a combination drill tap that drills and taps a hole in a single operation, eliminating the need for a separate drill step before threading. Sized for 8-32 UNC threads with an H3 thread limit, this tool is ground from high-speed steel for reliable performance in low-carbon steel, aluminum, and similar machinable materials. The two-flute geometry clears chips during the tapping process. The drill diameter is 0.1375 inches, the thread length is 33/64 inches, and the overall length is 2-1/8 inches. It is used by machinists, maintenance technicians, and trade professionals needing fast, accurate tapped holes in production or repair work.

This combination drill tap is suited for through-hole and blind-hole tapping applications in sheet metal, structural components, and light fabrication work where 8-32 UNC machine screw threads are required. It is a common choice in HVAC panel fabrication, electrical enclosure assembly, and general mechanical maintenance where speed and accuracy in creating tapped holes matter. The H3 tolerance class keeps thread fit consistent for standard 8-32 fasteners across repeated use.

Key Features

• Drills and taps in a single pass, reducing setup time and tool changes
• 8-32 UNC thread form with H3 thread limit for consistent tolerance control
• High-speed steel construction for durability in common machinable metals
• Two-flute design promotes chip evacuation during cutting
• 0.1375-inch drill diameter with 33/64-inch thread length and 2-1/8-inch overall length

Compatibility

Designed as an OEM-style replacement or direct-use combination drill tap for applications requiring 8-32 UNC machine screw threads in machinable metals and plastics.

Installation Notes

This tool is installed in a drill press, CNC machine, or tapping head rated for combination drill tap operations. Cutting fluid or tapping oil should be used to reduce heat and extend tool life. Power down and secure the workpiece before beginning. Do not use in a standard hand drill, as consistent alignment is required to produce accurate threads.
