Iecho E13 E16 E18L E21 E73B E1 Cnc Knives Knife Blade

Iecho E13, E16, E18L, E21, E73B, and E1 are different iECHO-compatible CNC knife blades with distinct sizes and max cutting depths, so selection depends mainly on your required cut depth, material hardness, and whether you need drag or oscillating action. The table below compares the key specifications to help with selection and running decisions. Blade specification table

Blade	Type / Action	Total height / length	Width	Thickness	Angle
E1	Drag, round-stock kiss-cut	18.5 mm height	3.0 mm	3.0 mm	35°
E13	Drag, flat	50 mm length	8 mm	1.5 mm	Not listed; general-purpose drag
E16 / E162	Oscillating, flat	~25–34/40 mm height (varies by subtype)	5.6–6.0 mm	0.63–1.0 mm	45–55°
E18L	Oscillating, flat extended	42 mm length / height	6 mm	1.0 mm	75°
E21	Oscillating, flat	28 mm height	4 mm	0.63 mm	63° or 84° variants
E73B	(Typically drag / specialty)	18.8 mm blade width	18.8 mm width	Not clearly listed	Not listed

Use E1 when you need precise kiss-cutting or very shallow cuts in films, labels, or thin cartons so you do not cut through the liner.
Use E13 when you want a thicker, more robust drag blade for general cutting rather than very fine details, especially in boards and plastics.
Use E16 when you need oscillating action up to about 7 mm in medium-hard materials such as PVC, ABS, carbon fiber laminates, and gasket sheets.
Use E18L when you need the deepest oscillating cuts (up to about 24 mm) in thicker flexible or semi-rigid stacks like canvas, gaskets, boards, and films.
Use E21 when you want a compact oscillating blade with good depth (up to ~17 mm) for corrugated, foam board, felt, rubber, and textiles.
Use E73B when you need up to ~20 mm penetration and your holder/tooling is matched to this specific model; confirm material list with your blade vendor.
