Veritas Optical Center Punch - dead-on marking

Veritas Optical Center Punch
When drilling into materials -- especially hard ones, like metal -- it's important to create a dimple into which to place the drill bit. This keeps the drill form wandering as you apply pressure. The simple approach is to use an awl or a center punch. But what do you do, when you want to be incredibly accurate? Check out the Veritas Optical Center Punch! It's a specialized tool, to be sure, but one that ensures your holes are just where they need to be.

About the Veritas Optical Center Punch:
After you have carefully marked your spot, place the punch base and optical post over the spot, adjust it until the crosshairs on the 8X magnifying post are exactly on the mark, then replace the post with the A-2 hardened steel punch and tap the punch with a hammer. A high-friction O-ring in the gold-plated brass base keeps it from moving during this exchange, ensuring near-perfect accuracy. It is simplicity itself to use. As an added bonus, you can use the 8-power optical post as an inspection monocular in your shop. It has excellent depth of field and is easily focused freehand.

Here's where you can get the Veritas Optical Center Punch.

Here's a different brand of Optical Center Punch that comes with the two spotting lenses, TWO hardened steel punches (one 60° and one 120°) and a fitted wooden case. Nice! (I found this one in Amazon's Industrial and Scientific section.)

Good for aging eye that can't see up close. But with magnifier lenses on a head band a regular punch is fine. Still it is pretty isn't it? It would look good in my fancy wood tool box with the felt lining.
