Value Collection 00574186 6-32 Unc H3 Combination Drill Tap

Product Description

The VALUE COLLECTION 00574186 is a combination drill tap designed to drill and tap a hole in a single operation, eliminating the need for a separate drill bit and tap. Built from high-speed steel, this tool is suited for threading ferrous metals and other common shop materials. It cuts a 6-32 UNC thread form with an H3 thread limit, making it appropriate for applications requiring controlled thread tolerances. With 2 flutes and a 0.1115-inch drill diameter, it produces clean entry holes and adequate chip clearance for standard through-hole and blind-hole work in machine screw applications. Machinists, toolmakers, and maintenance technicians install this type of tooling in CNC machines, drill presses, and hand-held power tools.

This combination drill tap is used in light to medium fabrication, assembly, and repair work where 6-32 machine screw threads are required. Typical applications include tapping sheet metal enclosures, electronic housings, brackets, and general mechanical assemblies. The H3 thread limit designation makes it compatible with standard 6-32 UNC class 2B thread fit requirements found across a broad range of commercial and industrial fastening applications.

Key Features

• Drills and taps in a single pass, reducing cycle time and tooling changes
• 6-32 UNC thread form with H3 thread limit for controlled fit tolerances
• High-speed steel construction for durability in ferrous and non-ferrous materials
• 2-flute geometry provides adequate chip clearance in standard drilling applications
• 0.1115-inch drill diameter matched to 6-32 thread engagement requirements
• 15/32-inch thread length with a compact 2-inch overall length for versatile tool holder compatibility

Compatibility

Designed as a standard combination drill tap for 6-32 UNC threaded fastener applications in light fabrication, maintenance, and assembly operations where a single-pass drill-and-tap process is appropriate.

Installation Notes

This tooling is installed and operated by machinists or maintenance technicians in drill presses, CNC machining centers, or hand-held power tools capable of holding round shank taps. Ensure the workpiece is securely fixtured before operation and use appropriate cutting fluid for the material being threaded. Do not exceed recommended spindle speeds for the material and tool diameter. Inspect the tool for wear or chipping before each use, as a damaged combination drill tap can produce out-of-tolerance threads or break in the workpiece.
