Value Collection 00382234 Combination Drill Tap 1/4-28 H3

Product Description

The VALUE COLLECTION 00382234 is a combination drill tap designed to drill and tap a threaded hole in a single operation. It cuts a 1/4-28 UNF thread to an H3 thread limit tolerance, making it suited for close-tolerance threaded fastener applications in metal fabrication, maintenance, and mechanical assembly work. The cutting body is ground from high-speed steel (HSS) for durability across ferrous and non-ferrous workpiece materials. With an overall length of 2.5 inches and a drill diameter of 0.22 inches, this tool fits standard drill chucks and is sized for tight-clearance applications. Machinists, maintenance technicians, and tool-and-die workers use this type of tool to reduce setup steps on manual or CNC drill presses and hand-held power drills.

This combination drill tap is intended for threading operations in metal components where a 1/4-28 UNF fastener will be installed. The H3 thread limit makes it appropriate for standard commercial-fit thread assemblies. Typical applications include equipment repair, fixture fabrication, and production tapping in light to medium steel, aluminum, brass, and similar materials. The 23/32-inch thread length provides adequate thread engagement for most standard fastener installations in these material types.

Key Features

• Drills and taps in one pass, reducing setup time on manual and CNC equipment
• 1/4-28 UNF thread form for fine-thread fastener applications
• H3 thread limit tolerance for standard commercial-fit thread assemblies
• High-speed steel construction for use across ferrous and non-ferrous materials
• 0.22-inch drill diameter with 23/32-inch thread length and 2.5-inch overall length

Compatibility

Designed as an OEM-style replacement or direct-use combination drill tap for applications requiring a 1/4-28 UNF thread in standard drill press, CNC, or hand-drill setups accepting straight-shank tooling.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians using a drill press, tapping machine, or hand-held power drill with a compatible chuck. Always secure the workpiece firmly before operation and use an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Power down and de-energize any machine before changing tooling. Do not exceed the recommended RPM range for the workpiece material and tool diameter.
