The Wera 845 Hex Shank Single Flute Countersink in 16.5mm is a large-format option designed for demanding countersinking and deburring work on sizeable fixings and components. Its generous diameter makes it particularly well suited to heavy joinery, structural metalwork, and fabrication applications. Despite its larger size, the 1/4" hexagon shank maintains excellent power transfer from driver to bit, and the single-flute design continues to deliver efficient, unobstructed chip removal. Operation remains vibration-free and scratch-free throughout, protecting the surrounding material whilst producing a consistently clean and accurate countersink profile. Compatibility with DIN ISO 1173-D 6.3 holders ensures straightforward integration with professional quick-change systems.
