Micro Drill Bits

Micro drill bits create very small or micro-sized holes. They are best used with high RPM, coolants to reduce friction and reduce heat, and a slow feed rate.

Drill bits are made of durable cutter materials such as high-speed steel (HSS), carbide and cobalt.… Learn More

Drill point styles vary based on application. They have different point angles and style of cutting edges. The most common conventional style has a 118-degree point angle and is a good compromise between performance and price across a wide range of materials. Each style offers specific performance characteristics in different materials and drilling applications. Tool flute types are helical (curved) or straight grooves cut or ground into the body of the drill bit to provide cutting edges, enable removal of chips (also called swarf), and to allow cutting fluid or coolant to reach the cutting edges.

Another feature to consider is the shank, the portion where the drill bit is held by a tool holder. The shank transfers the torque to the drill bit. Drill bit diameter is the measurement around the bit’s shank. Drill bit cutter sizes are described by various sizing standards such as inch (English), metric, wire gauge (80 to 1), and letter (A to Z). This reflects the size of the hole being drilled. Standards ensure that dimensions are the consistent across manufacturers.
