HSS Cobalt Jobber Drills DIN 338 are a great option cutting tool for professionals working in metal fabrication, engineering, manufacturing, and maintenance industries. Designed to deliver superior strength and precision, these drill bits are specifically engineered for drilling hard metals and high-tensile materials where standard drill bits may struggle.
The term HSS stands for High-Speed Steel, a material known for its toughness and ability to retain hardness at elevated temperatures. When combined with cobalt, the drill bit gains enhanced heat resistance and wear durability. This makes HSS cobalt jobber drills ideal for demanding applications involving stainless steel, hardened steel, cast iron, titanium, and other difficult materials.
DIN 338 refers to the internationally recognised German standard that defines the dimensions and technical specifications of jobber-length drill bits. The jobber length is considered the industry standard because it provides an excellent balance between reach and rigidity. This versatile design allows the drill to remain stable during operation while offering effective chip removal for cleaner and more accurate drilling.
One of the standout features of HSS cobalt DIN 338 drills is their precision-ground point geometry. The common variant features a 135° split point tip that improves centering accuracy and reduces walking on the workpiece surface. This design helps operators achieve faster penetration with less force, improving both efficiency and hole quality.
HSS cobalt jobber drills are widely used across sectors such as automotive engineering, aerospace manufacturing, sheet metal work, and industrial maintenance. Their ability to maintain cutting performance under high temperatures means they often last significantly longer than conventional HSS drill bits, reducing downtime and replacement costs.
For best results, it is important to use suitable drilling speeds, consistent pressure, and appropriate cutting lubricants. Proper storage and handling will also help preserve the cutting edge and extend tool life.
Overall, HSS Cobalt Jobber Drills DIN 338 offer outstanding durability, precision, and reliability for professional drilling applications.
