Precise electric screwdriver 78 in 1 for electronics and 3D printing

Looking for a versatile and compact tool for electronics servicing, 3D printer maintenance and fine mechanics? This 78-in-1 set combines an electric screwdriver with an extensive set of precision bits in a practical square case – everything at hand and ready for immediate use.

Main advantages

• Electric drive for fast screwing without hand fatigue
• Circular 4× LED lighting for a clear view even in tight spaces
• 72 pcs precision bits made of S2 steel (PH, Torx/Trox, Pentalobe etc.) cover the most common screw types in electronics
• Magnetic bit holder for secure work with screws

Contents and design of the set

• Electric screwdriver with USB charging (connector type not specified)
• 72× precision bits (PH, Torx/Trox, Pentalobe etc.) made of durable S2 steel
• Durable, compact “square tube” case for safe storage

Usage tips

• When working with electronics, start with low load and use the electric drive only for pre-screwing; perform the final tightening gently by hand
• Always choose the correct bit profile/size – this reduces the risk of damaging the screw head and components
