Q1: What materials can I drill using this 19-piece HSS drill set?
A: This set excels at drilling mild steel sheets, non-ferrous metals (aluminum, brass, copper), wood, fiberboard, and tough plastics.
Q2: What is the benefit of the 19-piece set over the 13-piece set?
A: The 19-piece set expands your drilling range up to 10.0mm (compared to 6.5mm in the 13-piece set) in standard 0.5mm steps, allowing you to create larger holes without needing secondary reaming.
Q3: Are these drill bits compatible with standard power drills?
A: Yes, the straight round shanks fit into all 10mm and 13mm key or keyless chucks across cordless drills, impact drills, and drill presses.
Q4: How should I care for these bits during heavy metal drilling?
A: Run the drill at lower RPMs for larger diameters (above 6mm) and apply a few drops of cutting oil or lubricant to control heat generation and preserve the sharp cutting edges.
