Insert Bits
Popular Blue Demon Unitized Insert Bits have high quality tungsten carbide inserts on all cutting surfaces.
A special grinding process produces superior cutting edges for faster drilling. Patented Blue Demon
Deflectors minimize bit plugging by formation cuttings.
Use of high fluid volumes through a specially designed large water course gives speedy drilling through
sticky clay and shale. Results - less recutting of the drilled formations and faster removal of cuttings from
the hole.
