Abstract:
A piloted rock drill bit includes an integral body having a pilot drill section, a reaming section and a mounting base section extending along a longitudinal axis. The reaming section includes four wings extending from the longitudinal axis in an “X” pattern. A cutting carbide member is secured to each wing. Waste debris ejection slots extend radially into the reaming section between the wings. The pilot drill section includes a post and a leading carbide member. The leading carbide member includes a pair of sloped surfaces extending forwardly towards each other and intersecting at a leading cutting edge. The leading cutting edge and sloped surfaces extend along a crescent shaped arc. Forward air delivery bores extend through the body to forward discharge openings at the pilot drill section. Rear air delivery bores extend through the body to rear discharge opening at the waste debris ejection slots.

Claim (Index 1):
A piloted rock drill bit comprising:\n a drill bit body including a leading pilot drill section, a central reaming wings section and a mounting base section successively arranged about and extending along a longitudinal axis between drill bit terminal forward and rear ends; wherein said leading pilot drill section, central reaming wings section and mounting base section are integrally formed together and form said drill bit body; said mounting base section including a threaded bore adapted to threadingly engage and mount said rock drill bit onto a rotary percussive head of a drill; said central reaming wings section including a plurality of wings extending radially from said longitudinal axis; each of said wings having a wing pocket and a wing cutting carbide member secured in said wing pocket, said wing cutting carbide members projecting longitudinally in a direction towards said terminal forward end; said leading pilot drill section including a post extending from said central reaming wings section towards said terminal forward end; said post including a leading post pocket and a leading central carbide member secured in said leading post pocket, said leading central carbide member projecting longitudinally beyond said post towards said terminal forward end; a forward air delivery bore extending through said rock drill bit body from said threaded bore to a forward discharge opening located at said leading pilot drill section; waste debris ejection slots, wherein each waste debris ejection slot is juxtaposed between a pair of wings; and, rear air delivery bores, wherein each rear air delivery bore extends through said rock drill bit body from said threaded bore to a rear discharge opening located at a waste debris slot and between said leading pilot drill section and said central reap no wings section, whereby pressurized air within said threaded bore is forced through said forward and rear air delivery bores and out through their respective forward and rear discharge openings causing waste debris to be blown out of the hole being drilled through said waste debris ejection slots.
