As the exhibitors explain, the drills all feature a consistent edge preparation, protecting the cutting area and preventing premature chipping and flaking. A strong corner design across the range also increases stability and reduces the forces encountered when exiting the workpiece. Retaining their Titanium Aluminum Nitride (TiAlN) coating, all drills continue to be suitable for use across a wide range of machines and materials, such as stainless steel, alloy steels, cast iron and non-ferrous materials. This is claimed to make the Force X range an ideal choice for general engineering and sub-contract environments. The micro-grain carbide substrate, in conjunction with the TiAlN coating, provides high wear resistance and increased tool life, while the 140° split point geometry enables precise centering capabilities and low thrust forces.
Solid carbide drill with TiAIN coating
For all Force X products, the new generation of solid carbide multi-application drills from Dormer Pramet, CTW (Continuously Thinned Web) technology is now being deployed. It offers a very strong web design, which is said to reduce the thrust requirements and thus increase the tool life.
