Regal Cutting Tools 011107AS Spiral Point Tap 15/32-32

Product Description

The REGAL CUTTING TOOLS 011107AS is a spiral point plug tap designed for threading operations requiring a 15/32-32 UNS thread form. Manufactured from high speed steel with a bright finish, this tap uses a spiral point geometry to push chips ahead of the cut rather than packing them into the flutes. It carries a right-hand thread direction, an H3 thread limit for consistent tolerance control, and three flutes to support a wide range of machine tapping applications. It is suited for use in production environments and toolroom setups where thread quality and tool life matter.

This tap is intended for tapping through-holes in a variety of workpiece materials. The plug chamfer provides a moderate lead-in, making it appropriate for most standard through-hole tapping applications where a starting taper is not required and a bottoming finish is not needed. The H3 thread limit accommodates typical class 2B and class 3B tolerance requirements. It is compatible with standard tap holders and tapping chucks used on CNC machining centers, drill presses, and manual lathes.

Key Features

• Spiral point geometry pushes chips forward through the hole, reducing chip packing in through-hole applications
• 15/32-32 UNS thread form for non-standard unified thread applications
• H3 thread limit supports class 2B and 3B fit requirements
• Plug chamfer provides a reliable lead-in for through-hole tapping
• High speed steel construction offers a balance of toughness and wear resistance
• Bright finish, no coolant-through, right-hand cut, non-oversize

Compatibility

Rated for use in alloy steel, aluminum, cast aluminum, cast iron, die casting aluminum, free machining steel, high carbon steel, low carbon steel, medium carbon steel, nickel alloy, precipitation hardened stainless steel, stainless steel, and wrought aluminum workpieces.

Installation Notes

Installation should be performed by a qualified machinist. Before tapping, ensure the drilled hole diameter matches the recommended tap drill size for a 15/32-32 UNS thread. Secure the tap in a properly aligned tap holder to avoid bell-mouthing or tap breakage. Apply an appropriate cutting fluid for the workpiece material, and never back-drive a spiral point tap against the thread direction.
