Value Collection 00452433 Combination Drill Tap 3/8-16

Product Description

The VALUE COLLECTION 00452433 is a combination drill tap designed to drill and tap a hole in a single pass, eliminating the need for a separate drill bit operation. Built from high-speed steel (HSS), this tool handles the 3/8-16 UNC thread form with an H3 thread limit for consistent tolerance control. It features 2 flutes and a drill diameter of 0.3225 inches, with a thread length of 1.125 inches and an overall length of 3.375 inches. Machinists, maintenance technicians, and fabricators use combination drill taps to reduce cycle time on through-hole and blind-hole tapping operations in mild steel, aluminum, and similar machinable materials.

This combination drill tap is suited for production and maintenance applications requiring 3/8-16 UNC threaded holes in metalworking, mechanical assembly, and repair work. The H3 thread limit designation makes it appropriate for use with standard class 2B fit requirements, which covers the majority of general-purpose fastener applications. It is well-suited for use in drill presses, CNC machining centers, and tapping heads where controlled feed rates can be maintained.

Key Features

• Drills and taps in a single operation, reducing setup and cycle time
• 3/8-16 UNC thread form with H3 tolerance limit for class 2B fit applications
• High-speed steel construction for durability across a range of machinable metals
• 0.3225-inch drill diameter matched to 3/8-16 thread specifications
• 2-flute design promotes chip evacuation during the combined drilling and tapping pass
• 1.125-inch thread length accommodates standard material thicknesses for this thread size

Compatibility

Designed as a standard 3/8-16 UNC combination drill tap suitable for use in drill presses, CNC machining centers, and tapping heads that accept straight-shank tooling of the appropriate diameter.

Installation Notes

Combination drill taps are installed by machinists or maintenance technicians using equipment capable of maintaining a controlled, synchronized feed rate matched to the thread pitch. Secure the workpiece firmly before operation and use cutting fluid appropriate for the workpiece material to extend tool life and improve thread quality. Do not reverse the tool under power in a blind hole without confirming chip clearance, as packing can break the tool. Follow applicable workplace safety standards for rotating cutting tool operations.
