Boyistar Eight-Size Oval Punch Set
Eight individual oval punches with a size range for small strap and watchband openings, supplied with a plastic storage box.
CHOOSE THE TOOL FOR YOUR WORK
Choose an oval opening by width and length
This Boyistar assortment is useful when the opening you need is longer in one direction than a round hole. Eight separate oval punch sizes let you compare both width and length, rather than choosing only a nominal diameter. That matters for a watchband or strap fitting where a 3 × 8 mm opening is a different shape from 4 × 6 mm even though both are small slots.
The supplied sizes are 2 × 6, 2 × 8, 3 × 6, 3 × 8, 3 × 10, 4 × 6, 4 × 8 and 5 × 8 mm. The punches are described as polished alloy steel and come with a plastic storage box. The seller describes tapping the end with a mallet; neither a mallet nor a backing board is itemized with the set.
The tools arrive with anti-rust oil for transport, and the seller asks you to clean them before first use. Whetstone grinding is supported, without a specified angle or routine. Compare the WUTA rectangular punch if straight-sided corners are the shape you want, or the OWDEN assortment for circular holes. Those profiles should be chosen for the fitting, not treated as interchangeable because they can all be used on straps.
