Q: What size hole does it need?
It needs a 3/4" diameter hole (maximum 0.78"), and the post drops straight in before the clamp knob is tightened to wedge it in place.
05G1901 - Veritas Surface Clamp
This fast-acting surface clamp can be used anywhere you can drill a 3/4" diameter hole. The post has a wedging mechanism that anchors it firmly (horizontally or vertically) in material as thin as 5/8" (depending on the strength of the material), making it ideal for use in jigs and fixtures, e.g., sliding tables for saws.
The clamp arm (which slides easily on the post when tilted, but locks at 90°) has a 2 1/8" throat depth and can grip anything from veneer to material up to 3 3/4" thick (3 1/8" when the post collar is used as a depth limiter).
Anchor wedging is controlled by the brass knob on the post and clamping force by the knob at the arm tip. Used horizontally, the post collar acts as a material support. Used vertically, the collar is a rub ring that protects workpieces from accidental damage by the post rings. Precision machined from brass, steel and anodized aluminum, this is a versatile work support and clamp.

Yes, this surface clamp's wedging post anchors equally well horizontally or vertically, which is what lets it work in a sliding jig as well as on a benchtop.
The arm clamps stock from veneer up to 3 3/4" thick, or 3 1/8" when the post collar is used as a depth limiter for thinner material.
Yes, it's best to orient the post so the wedge expands parallel to the grain in the benchtop rather than across it, which helps avoid splitting weaker material.
A blind hole only needs to be 1 3/8" deep, or the post can go through material as thin as 5/8", depending on how the clamp will be anchored.
