Carbide Flat-Bottomed Drill

Product Description

The carbide flat-bottomed drill is a high-performance cutting tool designed for precision drilling and counterboring applications. Its unique 180° flat-bottomed drill point makes it ideal for counterboring, drilling on slopes, and curved surfaces. This design prevents deflection and enhances machining stability.

The drill features a low spiral angle and low rake angle. These design elements ensure high-quality surface finishes and produce sharp, burr-free cuts. Additionally, the wide chip clearance groove helps to efficiently remove chips during the drilling process.
