Overview
A single 4 inch arch punch from C.S. Osborne, model 149-4, UPC 01132. The largest individual size in the 149 line covered here, for holes well beyond what a boxed set like the K-14 provides.
Detail on this listing is limited to the size and UPC, with no review history yet. At 4 inches it is meant for large-diameter work rather than the smaller leatherworking holes a boxed set typically covers.
- 4 inch diameter
- UPC 01132
- Osborne 149 series
- Single hole, manual punch
Who it's for
Leatherworkers or fabricators who need a large 4 inch hole in soft material. Anyone needing smaller, more common sizes is better served by the K-14 set.
Pros and cons
- Covers a large 4 inch diameter not found in boxed sets
- UPC listed for straightforward reordering
- No material or finish detail given beyond the title
Performance notes
A single hole, hand-struck punch driven by mallet, in the same format as Osborne's smaller 149 series punches.
