Why do electric screwdriver prices vary between factories?

Electric screwdriver prices vary between factories because the products may look similar but use different motors, gearboxes, batteries, PCBs, bits, materials, testing standards, and packaging.

The main price differences usually come from:

Motor quality: basic brushed motors cost less than higher-performance coreless or brushless options

Gearbox: plastic gears are cheaper, while metal planetary gearboxes normally cost more

Battery: cell quality, capacity, protection circuit, and cycle life affect cost

PCB and control system: adjustable torque, automatic stop, display, LED, and speed control add cost

Torque consistency: better-controlled torque normally requires better components and testing

Runout: lower runout requires more accurate shafts, bearings, holders, and assembly

Bit material: S2 bits cost more than standard CR-V options

Bit machining accuracy: precise Torx, Pentalobe, Tri-point, and other profiles require tighter production control

Housing material: aluminum bodies and CNC parts cost more than basic plastic housings

QC standards: torque testing, aging, battery testing, runout inspection, hardness testing, and pre-shipment inspection all add production cost

Compliance: CE, RoHS, FCC, UN38.3, and other market requirements may add testing and documentation cost

Packaging: premium cases, EVA trays, custom boxes, and retail packaging increase unit price

Order quantity: larger volumes normally reduce the unit cost

This is why buyers should not compare electric screwdrivers only by appearance, piece count, or quotation price.

For ToolQeen OEM projects, we recommend comparing the motor, gearbox, battery, PCB, torque performance, runout, bit material, QC standard, packaging, and compliance documents together before selecting a supplier.
