Industrial Quality Installer Drill Bits - Wire Installation
 
     The term - BELL HANGER BIT - originated with their use to install door bells and bell telephone wiring systems in wood frame structures. Current
applications require the expansion of the line to install Security, Fire Alarm Systems, TV, Audio Visual, Computer, Airport and Boat Wiring Systems
along with a vast array of additional low voltage and electrical installations requiring the drilling of a hole and pulling or fishing wire thru.

Why are so many styles and types required by installers?

     Installers encounter the need to drill holes and pull wire through a variety of materials and combinations of wood, cement block, concrete,
metals, plastics, etc. In addition, Installers may require both straight thru drilling and wire pulling with a RIGID Bit as well as applications
requiring a FLEXIBLE Bit to product a curved path wire installation. It is not uncommon to require several styles when encountering
having to drill and pull wire thru an unexpected combination of wood concrete metal or steel plate requiring a HSS type drill bit
or other combinations requiring several bit types to complete the installation. Thus, a installer usually maintains a variety of Bit styles to meet the task.

Several of the B & A Installation bits are specifically designed and produced for general purpose drilling in a variety of composites in order to reduce
the variety normally necessary for installers when only encountering simple drilling and pulling jobs.

SB Series - HIGH SPEED STEEL - SPADE DRILL BITS


SM Series - Carbide Tipped Slow Spiral Masonry Drill Bits


Spade Bits, also known as paddle bits, are used for rough boring in wood. The cutters are equipped with spurs in an attempt to ensure a cleaner hole. Having small shank diameters relative to their boring diameters, spade bits shanks often have flats to prevent slipping in drill chucks. They are intended for use with electric hand drills. The Spade Bit is used when the installer needs to cut fast clean holes. It has two cutting spurs which scribe the hole to reduce "Break-out". It is commonly used by carpenters, electricians and plumbers.
