14 Gauge SMART-BIT Countersink 75mm Replacement Drills - 4 Pack

The SMART-BIT is a combination tool that simply and easily pre-drills and countersinks decking screws for hardwood, softwood and composite materials.

These replacement drills are easily swapped in and out of the tool via the grub screw. There are four (4) drill bits in total with this kit. The drill bits can last anywhere from 300 up to over 1000 drill holes, depending on various factors such as the density of timber or angle of the drill - be sure to drive in straight for clean and smooth operating.

Often used with hardwood timber such as Merbau, the quick, one step motion pre-drills your decking screws, and provides a neat countersink free of chipped, furry edges.

The Powerbolic bits have a special fluting that cuts through timber fast.

These are very popular amongst our deck building customers and we highly recommend them for anyone considering building a deck with stainless steel decking screws.
