Countersink Bit Set 6 Piece Square Left Cutting Bits

A 6 piece countersink bit set for cutting neat recesses so screw heads sit flush or slightly below the surface. The square left cutting bits give you a straightforward spread of common sizes for everyday fixing, fitting and repair jobs.

Used for timber work, sheet material, general workshop jobs and site repairs, this set is handy when different screw and fixing sizes come up through the day. It suits trade use, DIY repairs and home maintenance where a clean countersunk finish helps fittings sit properly and leaves a tidier result. When working on boards, panels or routine fitting tasks, having several sizes together saves time compared with buying single bits separately.

The set includes six sizes from 6mm up to 16mm, covering smaller countersinks through to larger holes. Keeping the full range in one pack makes it easier to pick the size you need, whether you're working at the bench or pulling tools from a toolbox on site. The square left cutting pattern keeps the set focused on straightforward countersinking work, and the mixed sizing makes it useful for regular maintenance and repeated fitting jobs where clean screw seating matters. It is also practical for keeping common countersink sizes together, so bits are easier to find and less likely to be misplaced between jobs.
