Overview
A 40 piece screwdriver set, model 70151, weighing about half a kilogram in total. That combination of a high piece count and low total weight points to a compact bit driven set rather than a case of full size individual screwdrivers.
Forty pieces at roughly 1.1 pounds combined works out to a small average weight per piece, which typically means a bit set with a single handle and interchangeable tips rather than forty separate full size drivers. Buyers should confirm the exact bit sizes and tip types in the listing photos before ordering for a specific job.
- 40 piece screwdriver set
- Model 70151
- Total weight about 0.5 kilograms
- Compact bit style format
Who it's for
Fits someone who wants a wide range of driver tip sizes on hand for electronics, small appliances or general assembly work in one compact case. Less useful for a tradesperson who needs a small number of heavy duty, full length screwdrivers for daily use.
Strengths and trade-offs
Drawn from this product's published specifications.
- Wide range of tip sizes in one 40 piece set
- Compact and light at roughly half a kilogram total
- Small average bit size limits use on heavy duty fasteners
- Exact tip types are not detailed in the listing data
Performance notes
With 40 pieces weighing about half a kilogram combined, individual bits are necessarily small, which favors precision work like electronics or furniture assembly over high torque tasks that call for a full size handle and shaft.
