kwb 121610 kuusikanta kärkisarja, 4/5/6 mm, S2-teräs, 25 mm, 3-osainen

This 3-piece hexagon bit set from kwb covers the three most common metric hex sizes—4, 5, and 6 mm—in a single compact pack. Unlike single-size bits, the set reduces downtime when switching between fasteners, and the 25 mm length fits standard bit holders and quick-release chucks.

Highlights

• Hex tip sizes: 4 mm, 5 mm, 6 mm
• S2 steel construction for high durability
• 1/4 inch hex shank (6.35 mm) fits all standard bit holders
• 25 mm bit length for good reach in tight spaces
• Corrosion-resistant metallic grey finish

In daily use

The bits are suitable for screwdriving and assembly tasks with power drills, cordless screwdrivers, and light-duty impact drivers. The S2 steel provides a balance of hardness and toughness, reducing the risk of tip rounding or shank twisting under load. The 1/4 inch hex shank ensures a secure grip in magnetic and quick-release holders, preventing wobble and cam-out.
