BROWN 1/4″ × 4″ Black-Oxide Twist Drill Bit — HSS

A 1/4-inch (6.35 mm) black-oxide HSS twist drill bit, 4 inches (≈102 mm) long, for general-purpose drilling in metal, wood and plastic. The high-speed-steel body handles steel, aluminium and other metals, while the black-oxide finish reduces friction, sheds chips and resists rust for longer bit life. The round shank fits any standard drill chuck, and the 118° point starts cleanly.
