The Dormer Force M assortment of drills provide a high level of productivity specifically for drilling stainless steel (or ISO-M) materials while operating consistently across a diverse variety of machines and conditions. This makes them suitable for high production, general engineering and subcontract environments.

Their Force M "material specific" drilling family introduction follows the recent launch of the Force X drilling family, which was designed for use in a wide range of materials.

All of the solid-carbide "Force" drills in the program feature a modified four-facet split point geometry, to enhance self-centering capabilities and improve hole quality. Also, this split point design improves chip formation, tool strength and wear resistance specifically in these tough ISO-M materials.

A unique feature of all "Force" family drills is their continuously thinned web (CTW) technology flute construction. This offers a strong web design, while at the same time reducing thrust forces during drilling. Combined with the drills' consistent edge preparation, which provides predictable wear, CTW supports a highly consistent and reliable drilling process.

Each drill in the Force range is manufactured from premium micrograin carbide along with a multiple-layered titanium aluminum nitride (TiAlN) tool coating to provide an excellent combination of hardness and toughness, resulting in high wear resistance, long tool life and high productivity.

A strong corner design increases stability and reduces the forces encountered during drilling and especially during breakthrough at the exit surface, in both general drilling and cross-hole applications.

Supporting drilling depths of 3xD solid construction (R458) or coolant through (R467), and 5xD solid construction (R454) or coolant through (R463) the Force M drills feature internal coolant delivery in all sizes from 3mm to 16mm and 1/8" to 5/8".
