Wera 846 Hex Shank Triple Flute Countersink

The Wera 846 3-Flute Countersink Bit in 8.3mm offers a versatile mid-small size suitable for a wide range of everyday deburring, chamfering, and countersinking tasks. It provides a step up from the 6.3mm variant and is well-suited to slightly larger fastener applications without sacrificing control.

Built to DIN 335-C standard with a 90° cutting angle and three precision cutters, this bit delivers consistently clean results. The ¼" hex shank ensures strong power transfer and compatibility with DIN ISO 1173-D 6.3 holders. The finely-tuned material elasticity gives the bit excellent resilience, and the triple-flute geometry keeps chips clearing freely while keeping tilt risk low.
