Standard Drills: Versatile Workhorses at ToolsEngg.com
Standard drills, or twist drills, form the backbone of CNC machining with their helical flutes for efficient chip removal and precise hole-making. Available at ToolsEngg.com, these HSS and carbide tools suit general-purpose drilling across industries like automotive and manufacturing exports from India.
What Are Standard Drills?
These versatile tools feature a 118°-135° point angle, parallel shanks, and flute lengths from stub to extra-long series per DIN 338/340 standards. Jobber series dominate for through-holes up to 5xD, while coatings like TiN enhance performance on mild steel and aluminum. ToolsEngg.com stocks sizes from 0.5mm to 50mm for mills, lathes, and drills.
Key Advantages
Standard drills deliver cost-effective precision with h8 tolerance, self-centering action, and adaptability to portable or CNC setups. They handle ferrous/non-ferrous metals at high speeds, reducing setup time versus specialized tools. Ground versions ensure burr-free finishes, ideal for threading preparation.
Applications in Machining
Perfect for general fabrication, maintenance, and prototype work in engine components, brackets, and fixtures. In export machine shops, they support high-volume production of tapped holes and dowel pins.
