Cleveland C86115 Spiral Point Tap 1/4-28 UNF Cobalt TiAlN 3 Flutes

Cleveland C86115 Spiral Point Tap

The Cleveland C86115 is a spiral point tap designed for creating unified national fine threads in metalworking applications. It suits machinists and maintenance technicians who need reliable thread cutting in through-hole operations. The cobalt construction with TiAlN coating provides enhanced wear resistance during production runs. This tool addresses the need for accurate 1/4-28 UNF threads in industrial settings.

Thermals noise and power draw

As a hand-operated or machine-driven cutting tool, the tap generates negligible heat and noise during normal threading operations. Power consumption depends entirely on the driving equipment used rather than the tap itself. The TiAlN coating reduces friction at the cutting edges, which helps maintain lower temperatures at the thread interface. No electrical or pneumatic supply connects directly to this accessory.

1/4-28 UNF thread specification

The defining specification is the 1/4-28 UNF thread form with a 2B class of fit and 75 percent thread drill size of 5.45 mm. This determines compatibility with matching fasteners and tapped holes in unified fine thread assemblies. Builders requiring coarse threads, metric pitches, or different diameters must select an alternative tap. The three-flute spiral point geometry optimises chip ejection ahead of the cut in through-hole work.
