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 handheld jobs or shop production.
