To enhance the drilling performance of long self-drilling screws through thick steel plates, consider the following strategies:
Choose a larger drill point size (e.g., #5 or above) for steel plates thicker than 6mm to ensure stronger drilling capacity.
Use screws made from high-strength materials like SCM435 or 10B21, treated with heat hardening to ensure the drill tip is harder than the steel being drilled.
Optimize the drill point design, using features like double cutting edges, U-shaped grooves, or triple-point flutes to improve chip removal and reduce resistance.
Control the drilling speed and pressure when using power tools. Too fast can cause slippage or overheating; too slow may cause the screw to fail to penetrate.
To prevent stripping or burning, consider pre-drilling pilot holes or using a step-drilling process for extremely thick steel.
Apply lubricants when needed to reduce friction and heat, enhancing drilling efficiency and extending screw life.
