Tests show the BLIZZARD BIT™ out performs all other high speed steel 135° split point heavy duty drills. Made of proprietary steel that keeps the drill cooler than all other high speed steels. Runs at higher feeds and speeds than other high speed steel drills. Priced at high speed but performs similarly to cobalt. Improved lubricity of the drill, due to a special oxide and gold finish. Centers quickly with 135° split point. Heavy duty construction allows for hand held jobs or shop production.
