Wera 7 Piece 847 Combination Tapping Drill Bit Set

The Wera 847/7 Combination Tapping Drill Bit Set is a 7-piece HSS tap and drill set designed for threading and drilling in a single operation, ideal for mobile repair and assembly work on site.

Each combination tap bit features a hexagonal shaft for secure power transfer and is manufactured from high speed steel (HSS) with precisely tuned material elasticity for extended durability. The design delivers excellent centring properties, clean cutting action, effective chip removal, and reliable return movement with minimal tilt risk.

The set is fully compatible with ¼" drive holders conforming to DIN ISO 1173-D 6.3, and comes complete with a Wera Rapidaptor universal bit holder for fast, tool-free bit changes. This makes the set equally at home in a power screwdriver or the chuck of a corded or cordless electric drill.

Six HSS combination tap bits are included, covering metric thread sizes from M3 through to M10 — a practical range for contractors, engineers, and maintenance professionals working across a variety of materials and applications. The entire set is housed in a robust plastic storage box for organised, secure transport between jobs.
