💡 What is a good way to choose carbide drill bits for hard steel drilling projects? Carbide bits offer excellent hardness and heat resistance; pick grade like K20, ensure a rigid setup, and use appropriate speeds and feeds for best life and performance. Handy guidelines: - High-grade carbide (K20) for wear resistance - Use a rigid drilling setup (drill press or CNC) - Choose proper speeds/feeds; wet drilling can help with heat - Regularly sharpen and inspect for wear
