HOLEMAKER Gold Series Annular Cutters are an industrial quality cutting solution preferred by the industry for their exceptional cutting performance and life. The 25mm depth gold series annular cutters, with titanium nitride coating, are made with M2AL high-speed steel alloy material with a hardness of up to 67.5 HRC, designed for increased endurance of the cutting edge and tool life. Multi-cut geometry provides smooth and fast cutting, with decreased chatter. This also increases the cutter’s ability to remove the swarf away from the cut and helps to enhance centering.
