Wera 846 Hex Shank Triple Flute Countersink

The Wera 846 3-Flute Countersink Bit in 16.5mm is designed for larger-scale countersinking, chamfering, and deburring tasks where a wider cutting diameter is required. This size is particularly useful for heavy-duty metalwork, larger fastener heads, and applications demanding a pronounced chamfer or countersink profile.

Built to DIN 335-C with a 90° cutting angle and three precision cutters, it handles demanding work with ease while delivering consistently clean results. The ¼" hex shank provides very good power transfer and suits DIN ISO 1173-D 6.3 compatible holders. Finely-tuned material elasticity ensures the bit withstands tough conditions, and the triple-flute design keeps chips clear and minimises tilt risk throughout operation.

Features and Benefits:
• Hex shaft for very good power transfer
• Finely-tuned material elasticity for great durability
• Very good centring properties
• Perfect chip removal
• Precise return movement
