Value Collection DT22HEX-10-32 Combination Drill Tap 10-32

Product Description

The VALUE COLLECTION DT22HEX-10-32 is a combination drill tap designed to drill and tap a hole in a single operation, eliminating the need for separate drilling and tapping steps. It is sized for 10-32 unified fine (UNF) thread and features 2 flutes with a 135-degree split point for accurate positioning and reduced thrust on entry. The body is machined from high-molybdenum high-speed steel (HSS-E), which offers improved hardness and heat resistance compared to standard M2 high-speed steel. A gold-tone oxide coating provides additional lubricity and mild corrosion protection. This tool is installed by machinists, maintenance technicians, and tool-and-die professionals working in metal fabrication, HVAC equipment assembly, and general industrial repair.

The DT22HEX-10-32 is suited for through-hole and blind-hole applications in ferrous and non-ferrous metals where a 10-32 threaded fastener is required. Typical applications include sheet metal enclosures, electrical panels, HVAC equipment brackets, and light structural components. It is used in both manual hand-tap holders and low-speed CNC or drill-press setups where feed rate can be controlled precisely to match thread pitch. The 5/8-inch thread length supports standard fastener engagement depths in light- to medium-gauge material.

Key Features

• Drills and taps in one pass, reducing setup time and tool changes
• 10-32 UNF thread size for fine-pitch fastener applications
• High-molybdenum high-speed steel construction for extended tool life in hard materials
• 135-degree split point improves self-centering and reduces walking on entry
• 2-flute design aids chip evacuation in through-hole and short blind-hole applications
• Gold oxide coating adds lubricity and mild protection against corrosion

Compatibility

Designed for use in standard drill-tap chuck holders, T-handle tap wrenches, and low-speed drill press or CNC setups accepting a straight shank tool sized for 10-32 thread production.

Installation Notes

Secure the workpiece fully before beginning; unsupported material can grab and snap small-diameter combination tools. Use a cutting fluid or tapping oil appropriate for the workpiece material to reduce heat buildup and extend tool life. Set spindle speed conservatively — combination drill taps are more sensitive to speed and feed mismatch than standard twist drills. Inspect the flutes for chip packing after each hole in blind-hole applications to prevent tap breakage.
