21-Piece 2.5" Hex Head Allen Wrench Drill Bit Set, 1/4" Hex Screwdriver Bits Set with Durable Magnetic Impact Bit Holder, SAE & Metric Allen Key, S2 Steel, Mechanic Home Repair

A good assortment that works well.

Got these on a deal and was impressed with the quality. I've used a few sizes and they fit well and seem to hold up under tension. I like the extension with the quick release as well. I plan to buy a second one to ship with our tradeshow supplies so we'll always have a set with us.

Complete and high quality Allen wrench drill bit set! Having both SAE and metric in one set is perfect. The S2 steel bits are strong and durable, the magnetic holder is very convenient, and the 21-piece set covers everything I've needed. Great value for the price!

Good quality steel. Hopefully on a par with Bosch, but definitely better than lower grade steel so often found from China

Very handy and price to match

I use these almost every day. I love that these are magnetic. Inexpensive option, and they seem to be holding up.

Great for the hobby woodworker

So much easier than the old wrench that is uncomfortable to use when removing or setting the allen screw or bolt. I first used them on an old musket that I was restoring with multiple rusty Allen screws and these fit great with no slippage or stripping. It will make life easier for you if you have multiple projects. I use it both with a drill or a hand driver. No problems.

Exelentes Superan la calidad esperada.

Great little set, very handy to have around when in need. I use these everywhere I can without having to use regular Alan key.

Excelente, buen producto para trabajos que no exigen demasiado. Puntas NO imantadas
