Corner rounders – Material

A radius cutter can round different materials. Simple clips can be used to cut paper, photos and possibly laminated documents. Professional and robust equipment cuts larger thicknesses and aluminum foils in one operation.

The supply (at Amazon)

Based on the supply on Amazon, we have examined the assortment of the various manufacturers and suppliers. We were able to divide the providers into two categories. On the one hand, the group that offers “custom” corner rounders or corner punches, and on the other hand, a group that offers similar corner rounders.

Custom corner rounders

Corner Cutter – Sunstar Kadomaru Pro

One of the most popular corner rounders is the Corner Cutter – Sunstar Kadomaru Pro. This handy paper cutting device is designed in such a way that radii with three different sizes can be punched. For this purpose, the Corner Cutter Clips offers three different sizes S, M and L. These sizes correspond to 3, 5 and 8 millimeters respectively. To use one of these radii, the corner scraper does not need to be modified. For each radius, the Corner Cutter has an inlet on the side. To cut, simply squeeze the cutter.
The Corner Cutter can cut up to five sheets at a time, according to its users. In addition, business cards, photos and laminated materials can be rounded off.

Olympia 4 in 1 Set A 230 Laminating Set for A4

When laminating, corner rounders are a popular tool to round off the resulting and possibly sharp corners. That’s why radius cutters are a popular accessory among laminators. One of the most popular laminating sets is the Olympia 4 in 1 Set A 230*.

This includes the Olympia A230 laminator, a cutting ruler and laminating foils as well as a corner rounder. This is a simple clip, but it can cut not only laminated materials, but also paper and photos.

Another popular set is the Starter Set 12326 4-in-1* from Genie. This one features similar equipment to the Olympia set.

Clips, combination devices and professional punches

To give you as quick an overview as possible, we have first summarized the radius cutters of the suppliers with a very similar range in the table below. The table includes a total of three types of corner rounders.

Corner rounder clips

Clips are very simple corner cutters. Only one radius size can be cut at a time. The advantage of clips is that they are small and handy. Besides, this kind of corner scraper is very easy to use. To round a corner, simply slide the paper into the clip and squeeze the small radius punch between your thumb and forefinger. For those who need a corner scraper every now and then, a clip is a good choice. When buying it should be noted that these corner rounders can only cut a certain radius. They are also designed for thinner materials. There are no replacement parts for these corner rounders, so a new clip must be purchased if the punch wears out. However, since these radius cutters are quite inexpensive, this does not matter too much.

Combi devices

This paper cutting machine is suitable for cutting round corners as well as for normal punching. The design and operation are the same as those of a hole punch. This combination tool* punches normal 6mm round holes, long holes with a size of 3 to 14mm and features a corner cutter with a 4mm radius. The hole formats can be changed without tools. According to the manufacturer, up to 20 sheets can be cut at once in one operation. The price differences on Amazon seem to depend on the provider, as well as whether it is a Prime product and whether a positive review has already been given. The devices themselves otherwise only differ in color. All those who are looking for a hole punch with a useful additional function are well advised with this combination device in our opinion.

Professional punches

This professional corner punch is a flexible workhorse. On one hand, according to the manufacturer, stacks up to 10mm thick (approx. 100 sheets) can be punched. In addition, beside round corners, other punching patterns* can also be used. Thus, both round corners and angular shapes can be punched. Another feature is that the professional punch can be converted into a thumb hole punch. Calendar sheets can be made with such a punching machine.

This corner rounding tool is suitable for a wide range of materials. These include papers, foils, laminates and Alu Dibond Kappa panels. The included accessories differ between the individual providers. A punching tool with a 6mm radius is always included. Depending on the manufacturer, tools with 3.5 and 10 millimeters are also included as accessories. All other formats can be purchased as additional accessories.
