If you drill wood, plastic, metal, or concrete we''ve got the drills and the drill bit sizes you need to get the job done. Along with thousands of twist drills and metal drill bits, choose from a wide selection of counterbores, countersinks, augers and more.
Taper shank drill bits can be directly inserted into the spindle, driving sleeve, or socket of a compatible drill or lathe. This allows the bits to be installed and changed out more quickly than drill bits that are held in place with a chuck or collet.
Opt for the HSS metric drill bit set for steel, iron and non-ferrous metals, or choose the HSS Titanium and TCT masonry drill bit set for additional hardness and performance. Our HSS drill bits are versatile and will fit in a wide range of power tools such as the Milwaukee HSS Jobber drill bit set with 13 oxide coated drill bits or Milwaukee
Liming · Both cobalt and titanium drill bits are able to work fine for a long time. But each type has its own peculiar properties. For example, sharpening titanium bits will grind off their coating, cobalt bits are great for tough steel but are brittle, etc. Read our short cobalt vs titanium drill bits comparison to choose the right bits for your project.

Liming · High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is often used in power-saw blades and drill bits. It is superior to the older high-carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS History · Types · Surface modification · Applications · See also · References
