Unibor cutters come in many different diameters, lengths, shank sizes and material types. Any of the different configurations can be utilized to best suit your particular application. Using our M2 HSS range of annular cutters can economically complete most drilling applications. Our imperial diameters begin at 7/16” and go up to 4” in cutting diameter from 1” to 4” depth to cut. Exclusive to our company, Black Max Annular Cutters remove only a narrow wall of material, leaving behind a slug of material which is ejected at the end of the cut. Black Max cutters are manufactured fully ground, providing a longer working life, making them an industry leader in added value. These cutters are available in sizes ranging from 7/16” up to 2-1/16” in diameter, and are available in both 1” and 2” depth of cut.
