鑽頭組，A-Z 標準長度高速鋼

The metal index keeps everything organized and the HSS steel really bites into steel without much effort, I’ve already used about half the set on a car restoration project.

The letter sizes are clearly stamped on each shank, which saved me a ton of time hunting through the metal index on my last project. I’ve used about half of them so far and the HSS edges have held up nicely on mild steel without any chipping.

The metal index keeps everything organized and easy to grab, which I appreciate on the shop bench. Every letter from A to Z is there, and the jobber length feels solid for everyday drilling without being unwieldy. Just the right set for filling in gaps in my collection.
