Reach tight spaces - thanks to removable 110 mm extension rod

A detachable 110 mm extension rod clips on for extra reach and pulls free when access is cramped. The bit can be used independently without the extension rod for confined work.

Access recessed screws inside cabinets, behind brackets or within small enclosures with less awkward angling and fewer position changes.

Controlled fastening - with three-speed 45-tooth precision ratchet

A 45-tooth ratchet geometry gives fine engagement points while three selectable speed settings change mechanical advantage. Rated for up to 20 Nm, the mechanism balances torque and control.

Choose lower settings for delicate electronics or higher settings for light mechanical assemblies to reduce the risk of stripping screws.

Durable, versatile bits - with 16-piece S2 alloy steel set

Bits are S2 alloy steel hardened to around 60 HRC and supplied as 16 pieces, eight of them double-ended to cover common types and sizes. The selection includes slotted, Phillips, Pozi, Torx and hex heads.

A broad mix of hardened bits covers most household and workshop tasks while resisting wear, so replacements are needed less often.
