Westward 1/2"-13 UNC Straight Flute Tap

This Westward straight flute hand tap cuts 1/2"-13 UNC threads with a taper lead. It is made from high-speed steel with a bright, uncoated finish and features four flutes. The tool is designed for right-hand threading in general-purpose applications. Machinists and maintenance technicians use it for through-hole or blind-hole work.

Check thread specifications

Verify that the workpiece requires a 1/2"-13 UNC thread form before ordering. Confirm the material is suitable for high-speed steel cutting tools. Ensure the drilled hole matches the correct tap drill size for this thread limit. The taper chamfer helps start threads straight in the hole.

Consistent cutting in extended operations

The high-speed steel body maintains hardness during prolonged use in steel or iron. Four flutes distribute chip load evenly across the cutting edges. The bright finish allows visual inspection of wear without coating masking. Taper lead reduces torque spikes when deepening threads in long production runs.
