Solid Carbide Drill Range Designed for ISO-M Materials
Dormer Pramet has extended its Solid Carbide Force X program with the Force M range, designed for stainless steel applications.
Dormer Pramet has extended its solid carbide Force X brand with the Force M range designed for stainless steel applications. Force M drills feature internal coolant delivery in all sizes from 3 to 16 mm and from 1/8" to 5/8". The tools are available in 3×D and 5×D sizes, with either solid or coolant-through construction. The Force M assortment of drills are said to provide high productivity for drilling stainless steel (ISO-M) materials while operating consistently across a variety of machines and conditions.
All of the solid carbide Force M drills feature a modified four-facet, split-point geometry to enhance self-centering capabilities and improve hole quality. This split-point design is said to improve chip formation, tool strength and wear resistance specifically in ISO-M materials. Another feature of Force drills is Continuously Thinned Web (CTW) flute construction which, according to Dormer Pramet, offers a strong web design while at the same time reducing thrust forces during drilling. Combined with consistent edge preparation, which provides predictable wear, CTW is said to support a consistent and reliable drilling process.
Each drill in the Force M range is manufactured from micro-grain carbide along with a multilayered titanium aluminum nitride (TiAlN) tool coating for hardness and toughness, resulting in higher wear resistance, longer tool life and higher productivity, says the company. A strong corner design is said to increase stability and reduce the forces encountered during drilling, especially during breakthrough at the exit surface in both general drilling and cross-hole applications.
Recent tap geometry refinement and advances in coating technologies have made the chip-less, cold-forming operation suitable for a wider range of workpiece materials.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
