BLUE DEMON UNITIZED BITS

BLUE DEMON UNITIZED INSERT BIT

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.
