Cleveland C58572 Spiral Flute Tap 5/16"-24 UNF 3 Flutes Bright

SKU CH-DEGS-6W0FH

A spiral-flute tap cuts 5/16"-24 UNF threads in three flutes with a bright high-speed steel finish

  • Product typeTaps
  • Spiral flute design clears chips efficiently in blind holes
  • High-speed steel construction resists wear during repeated threading cuts
  • 5/16"-24 UNF thread size fits standard fine-pitch applications
  • Three flutes balance cutting speed with thread finish quality
  • Bright uncoated surface suits general-purpose tapping in ferrous metals

Application and Purpose

The Cleveland C58572 is a spiral flute tap designed for creating UNF threads in a 5/16"-24 size. It suits machinists and maintenance technicians who need to cut internal threads in blind holes where chip evacuation is critical.

Capacity and Limits

The tap cuts a thread length of 11/16 in within an overall length of 2 23/32 in. It is built for a 75 percent thread drill size I and meets a class of fit 2B with an H3 thread limit. The three-flute geometry manages chips in softer materials but may load up in tougher alloys or deep holes beyond the stated thread length.

Build and Day-to-Day Use

Constructed from high speed steel with a bright uncoated finish, the tool resists wear during general-purpose threading. The right-hand thread direction and plug chamfer allow straightforward starting in through or blind holes. The spiral flute design pulls chips upward, reducing the need for frequent withdrawal compared to straight-flute alternatives.

Questions about this item

Will the 5/16"-24 UNF spiral flute tap work with my existing high-speed steel drill bits for the 75 percent thread drill size I?

The tap is designed for a 75 percent thread drill size I and is made of high-speed steel, matching common HSS drill bits used for that specification.

How can I confirm the Cleveland C58572 tap is cutting threads correctly after setup?

Check that the threads produced measure to a Class 2B fit with a right-hand direction and that the 3-flute spiral design evacuates chips cleanly during operation.

Does the Cleveland C58572 tap come with a handle or wrench, or must I buy one separately?

The box contains only the spiral flute tap itself; a compatible tap wrench or handle for the 5/16"-24 size must be purchased separately.
