New Emuge Tap Features Innovative Chip-Breaking Technology



Emuge Corp. has introduced a tap with chip-breaking capabilities that is designed for machining applications in the energy and related industries. The new tap features technology developed by Emuge that is designed to eliminate the formation of long continuous chips that commonly occur when tapping carbon steels, alloy steels and austenitic stainless steels, the company said.

The tap is designed with a newly developed cutting face geometry and spiral flute form, which combine to affect chip flow, chip curl and chip length. Emuge chip-breaking technology (CBT) produces short, broken, controllable chip formations that can eliminate flute clogging and potential failure of the machine tap due to chipped cutting teeth or breakage. This technology contributes to reliability of the threading process, eliminates machine down time required to clean chips, improves tool life, produces a better surface finish and also increases operator safety, the company said.

"Our new chip-breaking tap is a testament to Emuge's unwavering commitment to developing the latest cutting tool technology," said Mark Hatch, Product Director of Taps and Threads Mills at Emuge Corp. "The new chip-breaking design we've developed is going to drastically improve tapping in difficult applications such as in the oil field, petrochemical and power generation industries."

"Made of premium cobalt high speed steel and ground with eccentrically relieved threads which feature full pitch diameter relief, the tap featuring Emuge CBT provides greater tool life and machining efficiency than conventional taps," said a company spokesperson. "The taps are surface treated with TIN to reduce friction between the tap and work piece, which results in improved thread finishes and increased tool life in carbon and alloy steels, cast and forged steels, tool and die steels and 300 stainless steel up to 35 HRC.

"The new Emuge chip-breaking tap is ground with an increased pitch diameter, designated 2BX, which optimizes the gage tolerance for a 2B class-of-fit, in order to add an additional wear allowance for improved tool life. The tap is also made with Emuge's trademark long shank, DIN length for extra reach, improved chip evacuation, cooling and lubrication.

"Emuge has also designed the new chip-breaking tap to be used in both horizontal and vertical machining applications, which saves tooling changeover time and eliminates the need to stock two lines of taps in the tool crib. Also, a modified bottom chamfer is well-suited for blind holes."

The new tap featuring Emuge CBT is offered in inch sizes ranging from 1/2" to 2". Taps are now fully in stock at Emuge's North American headquarters.
