💡 How do contractors keep high speed steel twist drills performing well during back to back construction jobs? Picking the right geometry ensures steady chip clearance and reduces binding inside tough stock. Proper cooling methods keep the working tip stable during prolonged operation. Adjustable RPM controls prevent tip distortion while boring thick panels. Handy straight shank profiles snap securely into compact drivers for faster trade work. - Maintain even forward pressure instead of squeezing the handle too hard - Lower the dial speed when piercing hardened steel to avoid snags - Add a drop of light oil before punching through dense lumber boards - Rotate tired cutters regularly to keep grip strength high on rough jobs
