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 and 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 - The 135° split point geometry eliminates the need for center punching. Allows for easier penetration and increased life in high tensile materials.
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.
