3 1/2インチ 両端 プラス＆マイナスビット 10本セット（ホルダー付き）

The double-end design is a real time-saver—I flip the bit instead of digging through a drawer, and the 3 1/2-inch length reaches screws in tight spots without a wobble. Ten bits cover most of what I run into, and the holder keeps them from rolling under the workbench.

The holder keeps everything organized, and each 3 1/2-inch bit flips from Phillips to flat without hunting for another tool. I've already used them on a dozen small projects and they've held up fine.

Finally, a bit set where the double-ended design actually saves me time swapping between Phillips and flathead. The 3 1/2 inch length gives me great reach in tight spots, and the holder keeps everything organized in my drawer.
