The company’s Rekord DZ series taps are designed with superb chipbreaking capabilities for machining applications in the energy and related industries. The technology eliminates the formation of long continuous chips that commonly occur when tapping carbon steels, alloy steels and austenitic stainless steels.
 
The taps are designed with a cutting face geometry and spiral flute form, which combine to affect chip flow, chip curl and chip length. This chipbreaking technology produces short, broken, controllable chip formations that eliminate flute clogging and potential failure of the machine tap because of chipped cutting teeth or breakage. This technology contributes to higher reliability of the threading process, eliminates machine downtime required to clean chips, improves tool life, produces a better surface finish and also increases operator safety, the company says.
 
Made of premium cobalt high speed steel and ground with eccentrically relieved threads that feature full pitch diameter relief, the Rekord DZ Series CBTz provides much higher tool life and machining efficiency than conventional taps, the company says. The tap is surface treated with TiN to reduce friction between the tap and workpiece, which is designed to improve thread finish and increase tool life in carbon and alloy steels, cast and forged steels, tool and die steels and 300 stainless steel up to 35 HRC. 
 
The taps are 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 taps are also made with the company’s long shanks, DIN length for extra reach, improved chip evacuation, cooling and lubrication.
 
The company has also designed the new taps to be used in both horizontal and vertical machining applications, which saves tooling change-over time and eliminates the need to stock two lines of taps in the tool crib. Also, a modified bottom chamfer is especially suited for blind holes.
 

The series is offered in inch sizes ranging from ½” to 2”.
