Product Overview

Our unique Electroformed Diamond Slotted Inner Cut drill bit has tremendous number of advantages over other types of drill bits. They have a thin wall with a section of multilayered diamond matrix, designed for high speed, high production drilling. These electroformed drill bits have the maximum concentration of diamond, which offers strong interfacial bonding with the metal substrate, resulting in longer service life compared to other drill bits. The electroformed diamond also offers self-sharpening effect, which makes a dressing stone unnecessary. Upon damage, the worn surface will grind off and a new diamond layer will be revealed so there is no need for additional redressing. The electroformed technique requires high purity diamond and results in uniform diamond grit dispersion on the tool. Therefore the tool has better thermal stability and sharpness. The slots facilitate chip removal and heat dissipation. Due to the thin wall, the drill bits are fragile, so it is highly recommended for use in a true running production type drilling press such as milling and CNC machines. The cutting action of this drill bit is performed on both the inner and outer blade to create circular shapes with smooth edges.
