Cleveland C57214 Spiral Point Tap 1/2-13 Unc Hss

Product Description

The CLEVELAND C57214 is a spiral point tap designed for right-hand through-hole threading in metalworking applications. It cuts a 1/2-13 UNC thread with a plug chamfer, pushing chips forward through the hole rather than packing them into the flutes. Built from high speed steel with a bright finish, this tap maintains edge sharpness across a range of ferrous and non-ferrous materials. The H2 thread limit ensures consistent Class 2B thread tolerances. With a 3-flute design and an overall length of 3.375 inches, it is well suited for production environments where clean, reliable tapping is required.

This tap is used for through-hole tapping in alloy steel, carbon steel, and aluminum workpieces. The spiral point geometry is preferred in production settings where chips must be evacuated forward to prevent thread damage. It fits standard tap holders and is commonly used in CNC machining centers, drill presses, and manual tapping setups. The plug chamfer makes it appropriate for starting threads in through-holes rather than blind holes. It is installed and used by machinists, tool and die workers, and maintenance technicians working in fabrication or repair settings.

Key Features

• Spiral point geometry pushes chips forward, ideal for through-hole tapping
• 1/2-13 UNC thread form with H2 thread limit for Class 2B fit
• 3-flute, plug chamfer design for efficient thread starting
• High speed steel construction for use in alloy steel, carbon steel, and aluminum
• Bright finish with no coating for straightforward re-sharpening
• Right-hand cut, no coolant-through requirement

Compatibility

Designed for through-hole threading applications in alloy steel, aluminum, and carbon steel. Compatible with standard 1/2-13 UNC tap holders and tapping chucks used in manual and CNC machining equipment. Part of the CLEVELAND Series 1011.

Installation Notes

Always secure the workpiece and ensure the tap is properly aligned with the pilot hole before engagement. Use an appropriate cutting fluid for the material being tapped to extend tool life and improve thread finish. For CNC use, verify spindle speed and feed rate match manufacturer recommendations for the material and tap size. Inspect the tap for wear or chipping before each use and replace if thread quality degrades.
