45-Piece Bit Set with Tough Case

This DeWalt DW2166 set supplies 45 screwdriver bits organised in a connectable tough case. It suits tradespeople and DIY users who need a broad selection of Phillips, slotted and other common profiles for everyday fastening tasks. The patented bit-bar layout lets you pull the exact bit you need without fumbling.

Connectable Storage and Bit-Bar Design

The case links with other ToughCase+ units so storage expands as your collection grows. A clear lid shows every bit at a glance while the clip latch keeps the box shut during transport. Eight 55 mm double-ended bits and two 88 mm power bits handle both standard and deep-reach driving.

Steel Construction and Hex Shank Compatibility

All bits are made from steel with a 1/4 in hex shank that fits standard drill chucks and impact drivers. The set weighs 6.7 pounds, giving a solid feel without excessive bulk. No batteries are required for the bits themselves; the case simply keeps them protected and ready for the next job.

Questions about this item

How much heat does the DW2166 bit set generate during all-day use?

The DW2166 is a passive accessory with no motor or electronics, so it produces no heat of its own; any warmth comes from the drill or impact driver driving the bits.

What chuck type must my drill have to accept these 1/4 in hex bits?

A 1/4 in hex chuck or a 3-jaw chuck that grips 1/4 in hex shanks is required; the set includes 55 mm double-ended bits and 88 mm power bits designed for that interface.

Will the 55 mm double-ended bits reach recessed fasteners in older cabinetry?

The 55 mm length on the eight double-ended bits provides extra reach for deeper recesses commonly found in older cabinets and furniture assemblies.
