Working Principle

The internal coolant system delivers coolant directly to the cutting edge during machining, effectively reducing heat buildup and flushing chips away to prevent clogging. The straight flute design enables smooth, controlled chip evacuation, critical for soft metals that can easily stick and form built-up edges. The step drill geometry allows for drilling multiple diameters in a single pass, maintaining concentricity and improving processing efficiency.
