Veritas ドリルストップゲージ

I used to eyeball drill stops and end up with pilot holes poking through the back. The V-shaped notch actually centers on the bit so I can set the stop collar exactly where I want it, and countersinks come out even every time now.

Setting consistent countersink depths used to be guesswork until I got this little V-gauge. It centers on the bit and lets me lock in a stop length in seconds, and my hinge screws finally sit flush every time.

Finally, a simple way to get consistent countersink depths every time. The V-groove centers the bit perfectly, and the clear markings make setup a breeze.
