Drill Hog® 鋼製鑽頭量規 鑽頭尺寸檢查器 29種尺寸

I keep a drawer full of loose drill bits and this little gauge finally let me sort them in one sitting. The 29 holes run from 1/16" up to 1/2", so I could check every bit I own without guessing. Solid steel plate too, doesn't flex when you push a bit through.

I keep losing track of which bit is which in my loose pile, so this gauge has been weirdly satisfying to use. Dropping a bit into the right hole and having it sit flush takes about two seconds. The stamped sizes are easy to read even under my shop light.

The 29 holes cover everything from 1/16" up to 1/2", so I finally stopped guessing which bit was which in my messy drawer. Stamped numbers are clear and the steel plate feels solid, not flimsy like the plastic ones I've had. Takes two seconds to check a bit and get back to drilling.
