Twist micro drills are exceptionally small cutting tools specifically designed for drilling tiny, precise holes with diameters typically ranging from 0.05mm to 3.00mm. They feature a helical flute design that wraps around the drill body, creating sharp cutting edges. These cutting edges remove material as the drill rotates, forming a hole.

Despite these challenges, advancements in manufacturing technology have enabled the production of increasingly precise and reliable twist micro drills for a wide range of demanding applications.

Stub length drill bits are shorter versions of standard jobber length drills. This design prioritizes rigidity and precision.

Spot drills are specialized cutting tools designed to create a precise conical indentation ("center") in a workpiece. This serves as a highly accurate starting point for subsequent drilling operations, ensuring the drill bit doesn't wander and ensuring proper alignment.

A straight flute drill is a type of drill bit characterized by its straight cutting edges (flutes) that run parallel to the drill's axis. This design is particularly well-suited for drilling materials that produce short chips.

BAUCOR's engineers can review your design and provide feedback to improve manufacturability, cost effectiveness, and efficiency.

A countersink drill bit is a specialized tool designed to create a conical recess at the top of a pre-drilled hole. This recess allows screw heads or other fasteners to sit flush with or below the surface of the workpiece, providing a clean, professional finish.
