Collection: Drills, Drill Sets & Accessories

When the drill bit rotates, the cutting lips slice into the material along the shear plane, while the chisel edge at the center pushes material outward. The point angle and lip angle are designed according to the material being drilled: harder materials require a larger point angle, while softer materials need a sharper angle to prevent wandering and ensure clean holes

A drill bit consists of three main parts: the shank, the body, and the point. The shank is held by the drill chuck, the body contains the flutes, and the point forms the cutting tip. The tip is typically conical, with cutting lips that shear material along a chisel edge at the center. As the drill rotates, these cutting edges apply force to the material, exceeding its shear strength, which breaks the material and creates a hole

Difference Between Stub-Length and Jobber-Length Drills. Stub-length drills are shorter, more rigid, and better for shallow, high-accuracy holes, while jobber-length drills are longer, general-purpose tools for deeper holes and mixed-depth work.
