Pro-Tip: When using large diameter hole saws like this 4-1/8 inch model, significant torque can be generated, especially when the bit bites into wood or masonry. Always use a drill equipped with a side handle (auxiliary handle) and use both hands to maintain control and prevent wrist injury. Start at a lower RPM to establish the cut groove before increasing speed.
