Smart-Bit® #8 Pre-Drilling & Countersinking Tool Set

Model # 156515
SKU # 156515

Use for pre-drilling and countersinking #8 trim head screws

/ Each

Easily drill perfectly sized holes for #8 trim head screws with this Smart-Bit tool. The screw’s head diameter, head angle and countersink depth are pre-set in the Smart-Bit’s tool assembly. The shaft length is pre-set so the hole will be the correct depth. 

More great features: The Smart-Bit stop collar has a rubber O-ring and spins free of the drill bit so you won’t mar or burnish the wood. Tool stops when the hole is completed. 

The bit’s fluting cuts through dense composites and hardwood more than twice as fast as standard wood bits. In testing, the Smart-Bit drilled 300-500 holes before it needed replacing. A set-screw access and included hex wrench make replacing bits a snap.
