For cutting thin, soft parts like VEX Aluminum, this bit drills a hole easily and quickly. However, if you're cutting harder or thicker materials, ensure that the bit or metal do not get very hot. Taking breaks to let the workpiece cool down or using coolant or lubricant will improve drilling and maintain the bit's longevity,
