Wera05053459001 1/4 x 100 mm 899/4/1 Universal Bit Holder - Silver

Works great. Good magnet

I do steel stud framing. I really like this bit holder, solid construction, powerful magnet. The best part is 4" (100mm) length. Most framers typically use 2" or 6" bit holder, and have to switch depending on needs, i find this shaft is best of both worlds. Short enough to fit tool between 16" stud layout, or other tight areas, but long enough for screwing backside of 3-5/8" studs. Its only my screw-gun 90% of the time.

Muy buena.

Les embouts de la même marque sont très difficiles à retirer une fois mis dedans il aut carrément les retirer à l'aide d'une pince !

I watched a carpenter use one of these and felt tempted. I'm really pleased that I bought one. It helps with reach into awkward spaces but, more unexpectedly, it helps where there isn't much clearance between the screw and an upright, With shorter bit holders, the angle can cause the bit to jump but the longer length reduces the angle and the bit tends to stay in place.
