Value Collection DT22HEX-8-32 Combination Drill Tap 8-32

Product Description

The VALUE COLLECTION DT22HEX-8-32 is a combination drill tap designed to drill and tap a threaded hole in a single operation. It is sized for 8-32 unified coarse thread and features a 2-flute geometry with a 135-degree split point for accurate entry and reduced thrust. The cutting body is manufactured from high-molybdenum high-speed steel and carries a gold coating for improved lubricity and wear resistance. This tool is used by machinists, HVAC technicians, electricians, and other trade professionals who need to create tapped holes quickly in sheet metal, light steel, or similar materials without a separate drilling step.

The DT22HEX-8-32 is suited for tapping 8-32 threaded holes in thin to medium-gauge ferrous and non-ferrous materials. With an overall length of 2.5 inches and a thread length of 0.5 inches, it fits standard drill drivers, hand tap handles, and CNC or benchtop drill presses. It is commonly used in electrical panel assembly, HVAC equipment fabrication, plumbing fixture mounting, and general equipment repair where 8-32 fasteners are specified.

Key Features

• Combination drill-and-tap design completes drilling and threading in one pass
• 8-32 unified coarse thread form with 0.5-inch thread length
• High-molybdenum high-speed steel construction for extended tool life in ferrous materials
• Gold coating reduces friction and improves chip evacuation
• 135-degree split drill point for self-centering entry and reduced thrust force
• 2-flute geometry supports efficient chip clearing in through-hole and shallow blind-hole applications

Compatibility

Designed for use in applications requiring 8-32 threaded holes in sheet metal, light structural steel, aluminum, and similar materials. Compatible with standard drill drivers, tap handles, and drill press chucks that accept the tool shank diameter.

Installation Notes

A licensed machinist or qualified tradesperson should select appropriate cutting fluid or tapping oil before use to maximize tool life and thread quality. Ensure the workpiece is securely clamped before beginning the drilling and tapping operation. Use low spindle speeds appropriate for the material being tapped, and back the tool out periodically to clear chips when working in blind holes. Inspect the tool for wear or chipping before each use and replace if cutting edges show visible damage.
