A magnetic bit holder is a short shank that takes a 1/4 inch hex bit on one end and fits a drill, impact driver or handle on the other. The magnet keeps the bit and screw in line. The main choices are the length, the steel and whether it is meant for impact use.
The six holders below run from a stubby 57 mm piece to a 6 inch extension and a five pack. Sizes and materials come from each listing page and are the makers’ own claims. We have not used these holders ourselves. Where a listing is inconsistent, we say so.

The 6 Best Magnetic Bit Holders
1. BOSCH ITBH601 6 In. Impact Tough Magnetic Bit Holder
A single 6 inch holder in alloy steel with an extended torsion zone and a hardened core. The maker says it absorbs torque peaks from impact drivers and fits 1/4 inch hex drivers, and the listing weight is 27.22 grams. The bullets do not describe the magnet, though the title calls it magnetic.
Suits: impact driver work. Strengths: a torsion zone. Weaknesses: one piece and no magnet detail in the bullets. Skip it if you want a multi-pack.
