Accupro 34242-00T Spiral Point Tap 6-32 Unc Tin Coated

Product Description

The ACCUPRO 34242-00T is a spiral point tap designed for cutting internal 6-32 UNC threads in through-hole applications. Manufactured from powdered metal and finished with a titanium nitride (TiN) coating, it delivers extended tool life and improved wear resistance compared to standard high-speed steel taps. The plug chamfer style distributes cutting load across several leading threads, making it well suited for through-hole tapping where chip evacuation is a priority. At 2 inches overall length, this tap fits standard toolholders used in both hand tapping and machine tapping setups. The H2 thread limit holds tolerances appropriate for a 3B class of fit.

This tap is used in machine shops, maintenance environments, and light manufacturing where 6-32 UNC threaded holes are required in through-hole workpieces. The spiral point design pushes chips ahead of the tap rather than packing them in the flutes, reducing the risk of tap breakage in production runs. It is appropriate for use in softer steels, aluminum, and similar machinable materials typical of 6-32 fastener applications. Machinists, tool and die technicians, and maintenance mechanics are the primary installers.

Key Features

• 6-32 UNC thread form with 3B class of fit for standard thread tolerance
• Plug chamfer distributes cutting load and suits through-hole tapping
• Spiral point geometry pushes chips forward, reducing flute packing
• TiN coating increases surface hardness and reduces friction for longer tool life
• Powdered metal construction provides consistent grain structure and wear resistance
• H2 thread limit for controlled oversize tolerance

Compatibility

Designed as a direct-use tap for through-hole 6-32 UNC thread applications. Compatible with standard tap wrenches, T-handles, and CNC or manual tapping heads accepting round-shank taps of the appropriate diameter.

Installation Notes

Install and operate this tap using a properly sized tap wrench or machine spindle with appropriate speed and feed for the workpiece material. Ensure the workpiece is securely fixtured before beginning the tapping operation. Apply cutting fluid appropriate to the workpiece material to reduce heat buildup and extend tool life. Inspect the tap for wear or chipping before each use, as a damaged tap can seize in the hole and damage the part.
