Ball-end hex key set 1.5–10 mm

The Wiha 66990 is a nine-piece L-shaped hex key set made from chrome-plated alloy steel. Sizes run from 1.5 mm to 10 mm and include a holder for organisation. The ball-end tips allow angled access to fasteners in tight spaces. Suitable for general mechanical and maintenance work.

Who this suits and who should look elsewhere

Technicians and DIY users needing a compact metric hex set with ball-end flexibility will find this kit practical. Buyers who require imperial sizes, Torx profiles or insulated handles are not served by this product. The set also lacks a ratcheting mechanism or T-handle variants.

Deciding specification — size range and ball-end

The 1.5 mm to 10 mm metric range with ball-end tips on every key is the single specification that determines fit. If your fasteners fall outside this range or you need straight-end-only engagement, a different set is required.

Questions about this item

Will the chrome-plated alloy steel keys need replacement if the finish wears off?

The keys are made from alloy steel with a chrome-plated finish. Normal use should not require replacement unless the keys are physically damaged or stripped.

What is the largest hex size included before I reach the set's limit?

The set covers sizes from 1.5 mm up to 10 mm, so the 10 mm key is the largest provided.

Do the L-shaped keys get hot or slippery during extended use?

The chrome-plated alloy steel handles conduct heat and may become warm, but they do not generate heat themselves. Grip depends on user preference and conditions.
