A620 Drill for Stainless Steel

Product catalog summary

Overview: The document provides detailed information about the Dormer A620 high-performance stub drill, specifically designed for machining stainless steel and temperature-resistant alloys. It highlights the drill's material composition, geometry, and application recommendations.

Material Specifications: The A620 drill is manufactured from a cobalt-based high-speed steel (HSS-E, M35), known for its superior hardness and toughness. The cobalt content enhances the drill's ability to retain hardness at high temperatures, making it ideal for stainless steel applications.

Geometry Features: The drill features A620 point geometry with continuous relief grinding and chisel thinning. This design reduces thrust forces during drilling, improves centering capabilities, and eliminates the need for pre-centering in most applications.

Recommendations: The A620 is particularly suited for machine applications involving stainless steels and other hard-to-cut materials. It is available in a range of diameters from 2.5 mm to 13.0 mm, compliant with DIN 1897 standards.

Customer Benefits: The combination of material and geometry results in superior performance and extended tool life. The drill's low thrust forces reduce spindle wear, while its self-centering capabilities enhance hole quality and positional accuracy.

Performance Data: The document includes comparative performance data, showing the A620's efficiency in drilling 304 stainless steel compared to competitors. It also provides detailed tables of drill sizes, dimensions, and application suitability across various material groups.

Contact Information: The document lists contact details for Dormer Tools' offices worldwide, including locations in the UK, France, Netherlands, Slovakia, Russia, Italy, Spain, Belgium, Sweden, Finland, Norway, Denmark, Brazil, Canada, USA, Australia, New Zealand, China, India, South Africa, and Argentina.
