Dormer Pramet recently introduced a generation of multi-purpose solid-carbide drills with proprietary capabilities that it says elevates economical hole-making to new heights.The high performance of Dormer Pramet’s Force X and Force M products lies in its novel flute construction with continuously thinned web and rolled heel design, which enables better chip removal and easier re-sharpening.

The new drills feature a micro-grain carbide substrate and TiAlN coating. Thiscombinationprovides high wear resistance and prolongs tool life, making the drills suitable for a wide range of machines and materials, such as stainless steel, alloyed steel and cast iron.

Dormer R100/R120 bright-finish, solid-carbide, entry-level self-centring drills feature a 120° point angle. The most typical industry user of this range is general engineering, where the drills can satisfy multiple applications and materials.

Spotting drills R122, R123 and R125 provide an accurate hole location, helping to avoid drill deflection. Recommended prior to deep-hole drilling, spot drills typically have a tight tolerance point geometry with very short flute length.

David Risk, global product manager at Dormer Pramet,says: “The R100/R120 are entry-level general-purpose solid-carbide drills offering excellent tool life with consistently reliable performance. They’re ideal for both bench drilling and CNC machine applications, mainly for general engineering and maintenance, and are the logical choice for small batch production in all industry segments.

“The Force X and Force M series on the other hand, are high-performance coated solid-carbide drills, with or without internal coolant, which offer very low cycle times,” he continues. “They’re the perfect choice for large batch, high-volume production in CNC applications, mainly for the general engineering, airframe assembly and die and mould industries.”
