Arbor with 7/16" shank for bimetal hole saws
Features:
The Truper Expert 7/16" shank arbor is the indispensable heavy-duty accessory for safely and professionally using your large bimetal hole saws. Designed with a reinforced screw and bolt fastening system, this arbor is capable of withstanding the high torque required to operate bimetal hole saws ranging from 1 1/4" to 6" in diameter. It includes an adjustable 1/4" high-speed steel (HSS) pilot drill bit that can be set to any hole saw height, ensuring concentric and stable drilling. It is the perfect solution for contractors, electricians, and industrial installers who need to drill large diameter holes in metal, wood, or plastic using drill presses or rotary hammers with large chucks.
