From the Manufacturer

Our new high performance solid carbide spirals are engineered for faster feed rates and long cutting life. New super micrograin carbide formula offers extremely sharp and longer lasting cutting edges. Low helical grind shears material with more efficient chip ejection. The tool works less, runs cooler and out performs the competition. Our new precision machinery was designed and built to CMT spec's. We now manufacture solid carbide spirals with the tightest tolerances in the industry. You won't find a better performance in tooling.
