COMPONENTS OF STRAIGHT SHANK DRILL BITS
STRAIGHT SHANK
The straight shank is the connection part of the drill bit that is held by the drill chuck. Its cylindrical design provides stable clamping, accurate positioning, and reliable performance during drilling operations.
DRILL BODY
The drill body is the main working section of straight shank drill bits. It includes the flute structure and cutting area, providing strength, stability, and efficient chip removal during drilling.
Flutes
Flutes are the spiral grooves along the drill body. They help remove chips and debris effectively, improve cutting performance, and maintain smooth drilling operations.
CUTTING EDGES
The cutting edges are the sharp parts responsible for removing material during drilling. Accurate cutting edge geometry helps improve hole accuracy, drilling efficiency, and tool durability.
POINT ANGLE
The point angle is the angle formed at the drill tip, which affects drilling performance and cutting efficiency. Proper point geometry helps achieve accurate hole positioning and stable drilling results.
SURFACE TREATMENT
Surface treatments such as black oxide and coating processes improve the performance of straight shank drill bits by reducing friction, enhancing wear resistance, and extending tool service life.
