The Wera 846 3-Flute Countersink Bit in 20.5mm is the largest in the range, making it the go-to choice for heavy-duty countersinking, chamfering, and deburring of large fastener seatings and substantial chamfer profiles. It is well-suited to demanding metalworking and fabrication environments where maximum cutting diameter is required. Compliant with DIN 335-C and featuring a 90° cutting angle with three precision cutters, this bit handles the most challenging countersinking tasks with precision and control. The ¼" hex shank ensures excellent power transfer and compatibility with DIN ISO 1173-D 6.3 holders. Finely-tuned material elasticity delivers outstanding durability, while the triple-flute geometry ensures efficient chip removal and a low tilt risk even at this larger diameter.
