The iFixit Mako Driver Kit has 64 precision 4 mm bits in S2 steel - Phillips, flathead, Torx and security Torx, hex, Pentalobe, Tri-point, JIS, Gamebit and more - with an anodized aluminum driver that has a magnetic bit socket, a knurled grip and a swivel top. It adds a flexible extension, a 1/4 in bit adapter, a magnetic pickup and a SIM tool, all in a 7 x 4.3 x 1.5 in case whose magnetic lid works as a sorting tray. iFixit backs it with a lifetime guarantee.
Electrical engineers, hardware tinkerers and anyone who opens up test gear or prototypes will reach for it weekly.
It is for small precision screws only, not full-size high-torque work; opening tools, spudgers and tweezers are not included; and the lid is held by magnets rather than a latch.
Skip if they already own an iFixit kit, or only do heavy mechanical work.
