M.A. Ford - #71, 130° Point, Solid Carbide Micro Drill Bit

Solid carbide provides better rigidity than High Speed Steel (HSS). It is extremely heat resistant and used for high speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials.

Titanium Nitride (TiN) is a multi-purpose coating which increases chip flow in softer materials. The heat and hardness resistance allows the tool to run at higher speeds than uncoated tools.

Spiral flute reamers are used in blind and through-hole operations. They are used to bridge interrupted cuts.

Fast spiral bits have finer flutes and used in high speed applications. They are used on concrete, stainless steel and soft, nonferrous materials.

Straight shanks are used for general purpose applications. The shank is smaller than the drill bit diameter. They are used with portable drills and drill presses on ferrous and non-ferrous materials.
