China Carbide Tipped Concrete Percussion Drill Bits

Carbide Tipped Concrete Percussion Drill Bits
The tungsten carbide twist drill bit is the type produced in largest quantity today. It comprises a cutting point at the tip of a cylindrical shaft with helical flutes; the flutes act as an Archimedean screw and lift swarf out of the hole.
The twist drill bit was invented by Steven A. Morse of East Bridgewater, Massachusetts in 1861.The original method of manufacture was to cut two grooves in opposite sides of a round bar, then to twist the bar (giving the tool its name) to produce the helical flutes. Nowadays, the drill bit is usually made by rotating the bar while moving it past a grinding wheel to cut the flutes in the same manner as cutting helical gears.
Twist drill bits range in diameter from 0.002 to 3.5 in (0.051 to 89 mm) and can be as long as 25.5 in (650 mm).
