BG223254224 As a general rule, all tools like this are made with hardened steel driver 'bits' or inserts of varying quality and an aluminium handle is standard unless otherwise stated. Some may be 6061 T6 or the more expensive ones 7075 T6 hardened aluminium handles with twice the tensile strength and cost but titanium would be another twice the price or more if even available at any cost since it's not only unnecessary but undesirable for a driver tip or even handle body. Whilst very strong for its weight, titanium isn't as hardwearing as carbon steel, S2 tool steel or HSS typically used in these drivers. The best 'Allen' hex drivers I've found for a tight fit in the screwhead and with the most grippy handles are made by SAB who build R.C. helicopters, expensive but worth it.
