The Carl HD-430N is built for serious volume, but even heavy-duty blades wear. If your holes are getting ragged or the punch feels like it's fighting the paper, the HD-430MD spare drill is the fix. It's the exact blade for that model — no adapters, no compromises. Swap it in and get back to clean, consistent punching
