Same form, same fit, same geometry. It drops into the same holders and runs the same cut parameters, so nothing on your machine needs to change. On Zund tables it mounts in the KCT and KCM-S tools and in the C2 and C2P, using insert sleeve 40 for vinyl blades.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is through cutting?\u003c\/h3\u003e\n\u003cp\u003eThrough cutting means the blade cuts completely through all layers of the material, including any backing or liner. The cut piece separates fully from the sheet. With a 2.1 mm maximum cutting depth, the K7 handles standard self-adhesive vinyl and steps up to heavier flexible stock like tarpaulin, magnetic foil, and PVC banner without stalling.\u003c\/p\u003e\n\n\u003ch3\u003eRound stock carbide holds its edge\u003c\/h3\u003e\n\u003cp\u003eRound stock blades are ground on a cylindrical body rather than a flat one, which puts more material behind the cutting edge. That extra body resists deflection when you push speed on long vinyl runs. Combined with a carbide edge, the K7 stays sharp through more linear feet before cut quality falls off, which means fewer blade changes mid-job and fewer parts scrapped because the tail end of a run started tearing.\u003c\/p\u003e\n\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\n\u003ch4\u003eHow do I know this fits my machine?\u003c\/h4\u003e\n\u003cp\u003eIf you are currently running the \u003cstrong\u003eZund Z7 (5224068)\u003c\/strong\u003e, the K7 is your replacement. It also fits Kongsberg XP and C series, Gerber MCT, and Cutworx Apex tables. If you are not sure which blade you are running now, call us with your machine model and the tool it mounts in and we will confirm before you order.\u003c\/p\u003e\n\n\u003ch4\u003eWhat materials does it cut?\u003c\/h4\u003e\n\u003cp\u003eStandard self-adhesive vinyl is what this blade is built for. It also runs reflective vinyl, magnetic vinyl and magnetic foil, masking and pre-mask films, sandblast masking, polycarbonate film, window perf, removable wallpaper, PVC banner, tarpaulin, PTFE, stencil board, and model box. For rigid substrates like foam board, corrugated, or acrylic, you want a different geometry. Tell us what you are cutting and we will point you at the right blade.\u003c\/p\u003e\n\n\u003ch4\u003eWhat does round stock mean, and does it matter?\u003c\/h4\u003e\n\u003cp\u003eRound stock refers to the blade body shape. The K7 is ground from 3 mm round stock, so it seats in a round bore holder and can rotate freely as it tracks a curve. Flat stock blades are ground from rectangular material and mount differently. The two are not interchangeable, so match the stock form to your tool.\u003c\/p\u003e\n\n\u003ch4\u003eHow do I know when to replace it?\u003c\/h4\u003e\n\u003cp\u003eWatch the cut, not the calendar. When the vinyl starts to drag instead of part cleanly, when corners tear or lift, or when you have to add pressure to get the same result you were getting last week, the edge is gone. Running a dull blade past that point puts load on the tool and the drive, so swap it.\u003c\/p\u003e\n\n\u003ch3\u003eGetting the most from your cutting table\u003c\/h3\u003e\n\u003cp\u003eA fresh blade is a good start. But if you are going through blades faster than expected, or cut quality has become inconsistent, the blade is rarely the whole story. Cut depth, speed, pressure, and machine condition all affect how long a blade lasts and how clean it cuts.\u003c\/p\u003e\n\n\u003cp\u003eIt is worth asking: When was your machine last serviced? Are your parameters dialed in for this material? Is this the right blade geometry for what you are cutting? Could your operators use time with someone who runs these machines every day?\u003c\/p\u003e\n\n\u003cp\u003eFlatbed Tools offers machine service, preventive maintenance, operator training, and workflow consulting. If something is not cutting right, reach out. We have probably seen it before.\u003c\/p\u003e","brand":"Flatbed Tools","offers":[{"title":"Default Title","offer_id":45833670852652,"sku":null,"price":25.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0343\/5259\/4988\/files\/FBT_IG3_1_2.jpg?v=1738012037","url":"https:\/\/flatbedtools.com\/products\/k7","provider":"Flatbed Tools","version":"1.0","type":"link"}
