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 Specifications: Diameter: 16.5mm Length: 40mm Shank: ¼" Hex (DIN ISO 1173-D 6.3) Cutting angle: 90° Flutes: 3 Standard: DIN 335-C Contents: 846 3-flute Countersink Bit, 16.50 x 40mm
