Metric drill bit index for 1 to 13 mm — 25 holes in 0.5 mm steps, on three stepped rows with each size engraved.

A 105 × 72.5 × 30 mm stand for a 25-piece metric set. Its three rows step up toward the back, smallest bits at the front, and each size is engraved beside its hole.

Printed holes often come out slightly small, and every printer differs. Print a short row of the smallest bits first, then change the hole clearance in Customize if they are tight or loose.

Each version keeps its own size, file and license. An earlier version stays available if this one changes.
