The 5 mm holes (one vertical and one horizontal) in this tool holder accommodate any Fretz Micro-Miniature stake or mandrel. Tools are inserted horizontally or vertically and held in place with two hex head screws. The H-2 Tool Holder has a 8 mm tapered square shank that fits the H-1 Stake Holder, which is sold separately (see related products below).

Note: Fretz Micro-Miniature stakes and mandrels cannot be mounted directly in the H-1 Stake Holder. They must first be mounted in the H-2 Tool Holder.
