Main Types / Models of ITC CNC Knife Blades
From ITC’s catalog and catalogs of related suppliers, these are common blade types offered under the “knife blade” category.
| Blade Type | Typical ITC Model(s) | Characteristics / Use Case |
|---|---|---|
| Flat Drag Knife Blades | e.g. BDF-10, BDF-11, BDF-12DE, BDF-16, BDF-17, etc. | These are fixed-angle blades that “drag” across material. They’re good for cutting thin, flexible materials like vinyl, adhesives, foils, magnetic sheets, etc. |
|
Round Shank Drag Knife Blades |
e.g. BDR-1, BDR-2, BDR-3, BDR-116, BDR-117, etc. |
Similar to flat blades but with a round shank. Often used for kiss cuts (partial cuts) or softer to mid materials like foils, vinyl, light plastics. |
|
Oscillating Knife Blades |
e.g. BOP-20, BOP-21, BOP-22, BOP-23, etc. |
These blades oscillate (move up/down rapidly) so they slice rather than drag. They are better for thicker or more challenging flexible materials — fabrics, foam, soft plastics, etc. |
|
V-Cut / Angled / Specialty Blades |
e.g. BDF-70, BDF-71 (for V-cut) | Used when you need angular cuts (e.g. 45°, 90°) for folding, creasing, or forming corners. |
| Tangential Knife Blades |
(sometimes labeled under “T” or “SxT” variants) |
These blades can be lifted, rotated, and re-engaged by a servo mechanism. They’re good for complex cuts, thicker or stiffer materials (leather, gasket, composite) where drag knives might chatter or lose precision. |
| Rotary / Rotation Blades | e.g. BRR-25, BRR-28, BRR-32 etc. | These are blade wheels that roll over the material, useful for fabrics, carpeting, etc. |
ITC also provides shaders, lengths, lip angles, etc., which affect performance.
How to Choose Which Model to Use
When picking which ITC blade model to use for a job, consider the following:
-
Material Type & Flexibility
-
For vinyl, foils, magnetic sheets, adhesive films: Flat drag or round shank drag knives often work best.
-
For foam, rubber, fabric, soft plastics: Oscillating knives may cut more cleanly.
-
For stiffer or thicker materials (e.g. leather, gasket, composites): Tangential or specialty blades may give better control.
-
-
Material Thickness & Density
-
Thin materials → drag knife is often enough.
-
Thick or denser materials → oscillating or tangential is safer to avoid tearing or overloading the blade.
-
-
Cut Complexity and Precision
-
Simple straight or gentle curves → drag knives.
-
Intricate shapes, sharp inside corners → tangential knives since they can reorient.
-
Angular folds, V-grooves → use V-cut / specialty blades.
-
-
Machine Capability & Blade Mounting
-
Ensure your CNC has the mechanism (drag knife holder, oscillating tool head, or tangential servo) to support the blade type.
-
Check the blade’s shank size, angle, and fitting with your tool head.
-
-
Lifespan and Cost Efficiency
-
Sometimes a slightly more expensive blade is justified if it lasts significantly longer or gives better cut quality (less rework).
-
Also consider whether the blade is coated or made of carbide versus HSS.
-
Here are a few highlights:
ZUND Z16 Drag Knife Blade is a drag-knife style blade with a 55° angle, useful for angled cuts in certain materials.
Screen paper cutter knife blade is a more general-purpose blade that might suit light materials.
69 mm Double‑edge flat knife is a double-edge flat blade, useful for straight cuts in broader materials.
These help illustrate how blade geometry (edge, angle, curvature) changes their suitability.
Recommendation / Suggestion
If I were picking a “default” or “main” model to start with (for a general-purpose setup), I’d suggest:
A flat drag knife (one of ITC’s BDF models) as a go-to for thin to medium flexible materials (vinyl, foils, magnetic, adhesive sheets).
Additionally, an oscillating blade as a supplementary blade for materials that the drag knife struggles with (foam, rubber, thick plastics).
