Dewalt DWA1406 Combination Drill Tap 10-32 2B

Product Description

The DEWALT DWA1406 is a combination drill tap designed to drill and tap a 10-32 thread in a single operation, eliminating the need for a separate drill step before threading. Built from high-carbon steel with an oxide finish, it features a split drill point for accurate starting without center punching. The two right-hand flutes clear chips efficiently during the threading pass. At 1.87 inches in length and 0.22 inches in diameter, this tool fits standard drill chucks and tapping heads used in light metalwork and assembly applications. Machinists, maintenance technicians, and sheet metal workers install this type of tooling on drill presses and hand-held power tools.

The DWA1406 is suited for through-hole and blind-hole tapping in thin-gauge steel, aluminum, and other machinable metals where a 10-32 unified fine thread is required. Common applications include electrical enclosure assembly, HVAC sheet metal fabrication, and general light-duty machine shop work. The 2B class of fit produces a standard commercial thread tolerance appropriate for most fastener and screw-clearance requirements. Its compact length makes it practical for tight-clearance drilling and tapping in production environments.

Key Features

• Combines drilling and tapping into a single pass, reducing cycle time and tool changes
• Split drill point starts on contact without center punching
• High-carbon steel construction provides adequate hardness for threading steel and aluminum
• Oxide finish reduces friction and provides light corrosion resistance during use
• Right-hand flute direction compatible with standard drill and tapping equipment
• 2B class of fit meets commercial thread tolerance standards for 10-32 fastener applications

Compatibility

Designed as an OEM-style combination drill tap for use in standard drill chucks and tapping heads accepting tooling with a 0.159-inch drill diameter and 10-32 thread form.

Installation Notes

A licensed machinist or qualified maintenance technician should install this tooling. Secure the workpiece firmly before operation and use appropriate cutting fluid for the material being tapped to extend tool life. Do not reverse the tool in a blind hole without confirming flute direction compatibility with your equipment. Follow applicable shop safety practices for rotating cutting tools.
