The coating of cutting tools is essential to their usability and range of application, also influencing a tool's lifespan. Coating is thus as important as tool geometry and design.
Dormer Pramet has launched a new generation of solid carbide multi-application drills to deliver a greater level of performance and economy. Force X is the new family name given to the Dormer range of drills, which replaces its MPX assortment.
All existing product codes have been retained to ensure a smooth transition, but the incoming drills have received a significant upgrade, including new geometry, corner design and edge preparation.
The improvements apply to the 3xD R457 and R458 and the 5xD R453 and R454, bringing them in-line with the newly launched 8xD R459.
Retaining their Titanium Aluminium 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 makes the Force X range an ideal choice for general engineering and sub-contract environments.
As part of the enhancements, each of the Force X drills now include Continuously Thinned Web (CTW) technology, which provides a very strong web design, reducing thrust requirements during drilling.
They 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.
The micrograin carbide substrate, along with the TiAlN coating, offers high wear resistance and increased tool life, while the 140° split point geometry provides precise centering capabilities and low thrust forces.
Offering both solid and coolant feed options to improve cutting efficiency and swarf evacuation, the new Force X range offers high productivity and improved performance.
Meanwhile, Dormer Pramet has launched new solid carbide spotting drills and pre-tapping drills. Developed for fast and accurate spotting, the R6011 drill can be used in hydraulic and shrink fit holders when machining a range of work-piece materials. It offers 90° self-centering point geometry and TiAlN coating for increased tool life.
Providing a drill and chamfer in one, the R7131 reduces tool-cycle time and inventory. Available in specific pre-tapping sizes for metric threads, it includes coolant feed holes to improve swarf control and performance, while the TiAlN coating increases tool life.
