Dormer Pramet solid-carbide drill suits stainless steel

Dormer Pramet has extended its ‘Force’ programme of solid-carbide drills with a specific range for stainless steel applications. The Force M assortment provides a consistently high level of productivity, says the company, making the drills suitable for general engineering and subcontract machining environments.

Force M’s introduction follows the recent launch of the Force X drilling family for use in a wide range of materials. All Force drills feature modified four-facet split point geometry to enhance self-centring and hole quality. This design is also said to improve chip formation, tool strength and wear resistance.

A novel feature of the Force drills is their continuously thinned web (CTW) flute construction, which not only offers a strong web design, but reduces thrust forces during drilling. Combined with special edge preparation that provides predictable wear, CTW supports a consistent and reliable drilling process.

Each drill in the Force range is manufactured from micro-grain carbide to provide a combination of hardness and toughness, resulting in high wear resistance and longer tool life. In addition, a strong corner design increases stability and reduces the forces encountered during breakthrough when exiting the surface, in both general drilling and cross-hole applications.

Supporting drilling depths of 3xD (R467) and 5xD (R463), Force M drills feature internal coolant delivery in sizes from 3 to 16 mm and 1/8 to 5/8”.
