Rocaris 12パック 1/4インチ 六角シャンク ロング磁気ドライバービットセット 4インチ パワーツール (スロット+クロスヘッド)

This is a great set to have on hand. Works great for taking apart and repairing household items with recessed screws.

Not bad but the tips don’t fit the screws real well. If you’re going to use them a lot, better get a quality brand

There’s a tacky coating on it that feels like a toddler with maple syrup on his hands was working the assembly line. May have to soak these in degreaser, otherwise every bit of debris is going to stick to them.

seems to be well made and high enough quallity, The big thing with using these in a power tool will be to not over drive them.

Used one of the Phillips bits to drive about 20 3" screws into Douglas fir. Just finished the job about the time the bit was shot and could not drive any more screws.
