Milwaukee Tool 48-89-4872 Combination Drill Tap 10-24

Product Description

The MILWAUKEE TOOL 48-89-4872 is a combination drill tap designed to drill and tap a 10-24 UNC thread in a single operation. It features a 2-flute, right-hand configuration with a split-free drill point and a 1/4-inch hex shank for direct chuck or hex-drive compatibility. The tool is manufactured from steel and measures 2.22 inches in overall length. It delivers a medium class of fit, making it suitable for standard threaded fastener applications in metal fabrication, mechanical assembly, and maintenance work. Licensed trades and skilled fabricators use this type of tool to reduce process steps when threading ferrous and light non-ferrous materials.

This combination drill tap is suited for use in residential and commercial maintenance, mechanical fabrication, and light manufacturing environments. The 10-24 UNC thread size is a widely used coarse-thread standard in sheet metal, electrical enclosures, and equipment panels. The 1/4-inch hex shank allows direct use with standard hex-drive power tools, reducing setup time. It is a single-pass solution for operators who need to drill and tap without switching tools or repositioning the workpiece.

Key Features

• Drills and taps a 10-24 UNC thread in one pass, eliminating a separate tapping step
• 1/4-inch hex shank is compatible with standard hex-drive chucks and quick-change systems
• Right-hand flute direction and right-hand thread for conventional forward-drive operation
• Medium class of fit for standard threaded fastener assembly
• Steel construction for durability in ferrous and light non-ferrous materials
• Compact 2.22-inch overall length suits confined work areas

Compatibility

Designed for use in standard 1/4-inch hex-drive drill/drivers and drill chucks. Intended for applications requiring 10-24 UNC right-hand threads in sheet metal, electrical panels, and mechanical assemblies.

Installation Notes

Installation is performed by a machinist, electrician, or mechanical technician using a drill/driver or drill press equipped with a 1/4-inch hex-drive chuck. Secure the workpiece firmly before beginning to prevent movement during the combined drilling and tapping operation. Use appropriate cutting fluid for the material being tapped to reduce heat and extend tool life. Back the tool out periodically on deeper passes to clear chips and prevent binding.
