Super Primalloy® CONSTRUCTION - The proven, heavy duty construction of our Super Primalloy® Drills. MULTI-PHASE CRYOGENIC TREATMENT - Patented deep thermal cycle brings drills down to -300°F to alter and refine the molecular grain structure, relieve stress fracturing and increase durability & life. "N" SERIES NITRIDE TREATMENT - Nitride treatment case hardens the cutting surfaces for superior edge retention, faster long-term hole creation and longer service life. SUPER HEAVY DUTY 135° SPLIT POINT - 135° split point geometry eliminates the need for center punching. Allows for easier penetration and increased life in high tensile materials. MAINTENANCE LENGTH - Overall length reduced by an average of 15% to provide increased rigidity and breakage resistance. STABILIZED MOLECULAR STRUCTURE - Cryogenic treatment reduces brittleness and provides extended tool life. HIGH LUBRICITY SURFACE TREATMENT - Dark gold surface treated body provides excellent lubricity for increased drill life. MODIFIED FLUTE & WEB - Provides increased strength and durability. SUPER-TOUGH "M" SERIES ALLOY STEEL CONSTRUCTION - Superior tool steel provides exceptional wear resistance and longer life. FLATTED SHANKS - Virtually eliminates slippage in the drill motor and prevents damage to the drill and chuck (on sizes 3/16" and larger).MADE IN THE U.S.A.
