Frequently Asked Questions
What does the QianLi Screwdriver Bit Magnetizer do?
It re-magnetizes demagnetized screwdriver bits so they hold small screws securely, preventing dropped screws during precision disassembly work.
Which bits does it fit?
Bits up to Φ4 mm. The ring has a 4 mm inner diameter and 6.4 mm outer diameter, so it fits most standard precision screwdriver bits on the market.
Why does a bit lose magnetism?
High temperature, time-based decay, and impact can all demagnetize a bit. Sliding the magnetizer ring onto the bit restores magnetism to optimal strength.
How many colors are available?
Nine colors (C1G1–C1G9): fluorescent green, yellow, white translucent, black, purple, Christmas green, red, blue, and gray translucent — ideal for identifying bit types at a glance.
Does the silicone ring stay in place?
Yes. The anti-slip silicone ring is reinforced to keep the magnetic ring from falling off or shifting during use.
