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.
