Cleveland Spiral Flute Tap 5/16-24 UNF

This Cleveland spiral flute tap cuts 5/16 inch -24 UNF threads in a single pass. The high speed steel body handles general purpose tapping in steel and non-ferrous metals. A bottoming chamfer lets threads start close to the bottom of a blind hole. Three flutes provide balanced chip evacuation for cleaner threads.

Sustained cutting performance

The spiral flute geometry pulls chips up and out of the hole during continuous operation. This reduces packing and heat buildup when threading deeper holes or running multiple parts. High speed steel retains hardness at elevated temperatures so the cutting edges stay sharp longer. The bright finish allows visual inspection of wear without coating masking.

Build quality and daily use

The 3 flute design distributes cutting forces evenly across the tool body. A 2 23/32 inch overall length fits standard tap holders and wrenches. The H3 thread limit produces a class 2B fit for standard assemblies. Right hand thread direction matches common fastener requirements. The 75 percent thread drill size I simplifies hole preparation.
