Product Description

High Quality Sharp Hss Taper Shank Metric Twist Drill Set 50mm

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).

1.High temperature resistance, good wear resistance, and long service life.
2.Suitable for drilling difficult-to-process materials such as stainless steel SUS303, SUS304, SUS316, die steel, and titanium alloy.
3.Better wear resistance and good performance for drilling materials like ordinary steel, cast iron and copper-aluminum materials.
