HSS, HSS-E & Powder Metal Drills
HSS (High-Speed Steel) Drills
High-Speed Steel (HSS) drills are a versatile and widely used option for drilling in a variety of materials, including metal, plastic, and wood. They offer good durability and heat resistance, making them ideal for general-purpose drilling. HSS drills are cost-effective and provide a balance between performance and longevity.
HSS-E (High-Speed Steel Cobalt) Drills
HSS-E drills contain cobalt (typically 5–8%), enhancing their hardness, wear resistance, and heat resistance. This makes them well-suited for drilling tougher materials such as stainless steel, titanium, and high-strength alloys. Their increased durability allows them to maintain sharpness for longer periods, reducing downtime for tool changes.
Powder Metal Drills
Powder metal drills are made using a powder metallurgy process, which results in a tool with a fine-grained microstructure. This enhances strength, toughness, and wear resistance compared to traditional HSS drills. They provide superior performance in demanding applications, such as deep hole drilling and high-production environments, and offer extended tool life with reduced risk of breakage.
