HQMaster 45 Degree Vinyl Cutter Blades Lettering Blade for Graphtec Cutting Plotter, Red Cap Pack Of 10 with Springs

I've been buying these blades for almost 10 years. They have been terrific until now. A few weeks ago I got a new set and not one of them fit into the CB09 blade holder. I returned them and asked for a replacement. Of the second set of ten, only 2 blades fit into the blade holder. I returned them as well. I did get a set of 60 deg blades that work fine, so it's a bad batch. Really disappointed in these. I gave this item 3 stars because they have worked well in the past. Hopefully it's just a bad batch and HQMaster will figure out what is wrong and fix the problem.

Buena calidad

We have been cutting card-stock on our Silhouette machines for over 6 years now. We Bought these as a fill-up for our CB-09 blade holders (we have 4 in operation at any given time). My assumption was that all of these blades were made the same way... We had to make specific adjustments to these blades in order to get them to cut correctly (which is fair considering these are not all in a uniform height). However I was EXTREMELY disappointed to discover that over 1/2 of these blades would chip/dull after only a few cut jobs. This lead to a lot of wasted material, a lot of frustration, and a lot of wasted blades. Every 4th or 5th blade would hold up as expected and we continued to use it until it eventually dulled. But even at their best, these blades did not hold up to the previous CB-09 replacements we had. For comparison, the previous set of blades we purchased lasted us for the entire year. These hardly lasted an afternoon. In short, we will not be purchasing HQMaster again.

Price and quantity is a plus. But they go dull rather quickly.

The blades work really well on the Silhouette brand of cutters. They do require a special cb09 adaptor.
