Solid Carbide Drills Cut Stainless Steel
Dormer Pramet has extended its solid carbide drill program with a range for stainless steel applications called Force M.
The Dormer Pramet Force M assortment of drills are said to enable productivity for drilling stainless steel (or ISO-M) materials while operating consistently across a variety of machines and conditions. According to the company, this feature makes them ideal for high production, general engineering and sub-contract environments.
The drills feature a modified four-facet split-point geometry, which is said to enhance self-centering capabilities and improve hole-quality. Also, the company says this split-point design improves chip formation, tool strength and wear resistance.
Another feature is the continuously thinned web (CTW) technology flute construction. This enables a strong web design, while also reducing thrust forces during drilling. Combined with the drills’ consistent edge preparation, CTW supports a consistent and reliable drilling process, according to the company.
Each drill is made of micro-grain carbide along with multi-layered titanium aluminum nitride (TiAlN) tool coating to enable a combination of hardness and toughness, which is said to result in high wear resistance, longer tool life and higher productivity. According to the company, the corner design increases stability and reduces the forces encountered during drilling, in both general drilling and cross-hole applications.
Supporting drilling depths of 3 × D solid construction (R458) or coolant-through (R467), and 5 × D solid construction (R454) or coolant through (R463) the drills feature internal coolant delivery in sizes from 3 mm to 16 mm and 1/8" to 5/8".
An ongoing effort towards more efficient operations drove this shop to take a closer look at indirect material usage, subsequently leading to implementation of a new system for tracking toolroom inventory.
Some primary factors are often overlooked when considering how to justify the implementation of a bar feeder for turning operations.
Having strategies in place for managing chips is an important part of protecting the production process, from tool life to product quality.
