Size and materialEach metal drill bit has a diameter of 1/16"*2+5/64"*2+3/32"+7/64"*2+1/8"*2+9/64"*2+5/32"*2+11/64"+3/16"*2+13/64"+7/32"+15/64"+1/4"*2+5/16"+3/8" and is made of cobalt M35 high-speed steel (hss), which has superior toughness and durabilityDurability and applicable scenariosHigh speed steel improves the surface hardness and wear resistance of drill bits, allowing them to easily penetrate sturdy materials and have a longer service life. Suitable for various scenarios such as metal, wood, plastic, aluminum alloy, etcWithstand heavy blows and quick replacementsThe 1/4 inch hexagonal shank design allows the drill bit to withstand high torque transmission and heavy pressure. In addition, the drill bit is equipped with a quick replacement design, which facilitates the quick replacement of cutting toolsQuick drillingThe specially designed 135 degree segmentation point prevents the drill bit from moving during contact, making it easy to t drilling. The precise parabolic shape helps with rapid chip removal, reducing friction and heat accumulation. Its sharp cutting edges make it easy to cut on wood and metalWork efficiencyCombining high speed and durability, it is favored by electricians, plumbing workers, professionals. Suitable for soft metals such as metal, wood, thin wooden boards, aluminum, copper, etc., as well as for home diy, general construction, and home engineering projects
