This is a versatile bit with a special tip screw processing that allows for a stop hole and through holes. ● Ideal for tasks that require depth adjustment. Excellent effect when using a drill machine or electric drill. For use with an impact driver (12 V or above), it can drill holes up to 0.8 inches (21 mm). When using with a drill machine, it will not lift the wood while drilling work like normal screw type bits.
The triangle type bits require the force to push in when drilling the bit, but the stopper bit can easily be drilled with a lighter force. Even after the stopping hole processing is finished, there is no need to switch the rotation of electric tools such as impact drivers to reverse rotation, so you can easily pull the bit out by simply rotating it with the forward rotation of the blade. (Electric drills are especially effective)
