Iecho Bk Pk Tk Series Knife Cutting Machine Cutting Knives Blades

Iecho BK PK TK Series knife cutting machine Cutting Knives Blades

The IECHO BK, PK, and TK series digital cutting machines are equipped with a modular tool system designed to work with an array of specialized tungsten carbide blades. The BK and TK series commonly utilize larger flat-shank and round-stock blades, typically measuring around 1.5mm in thickness. In contrast, the PK series often employs smaller drag and oscillating knives, with blade thicknesses varying between 0.63mm and 1.5mm, depending on the specific model.

Blade compatibility across series is determined by the type of tool head installed on the machine. These include options such as the Universal Cutting Tool (UCT), Electric Oscillating Tool (EOT), and Pneumatic Oscillating Tool (POT), each tailored to different cutting applications.

Series	Common Thicknesses	Cutting Depth Range	Typical Applications
BK Series	0.63mm, 1.0mm, 1.5mm	1.1mm – 50mm	Cardboard, acrylic, foam board, MDF, ABS
TK Series	0.63mm, 1.0mm, 1.5mm	1.1mm – 50mm	Large-format textiles, carpet, gaskets, composites
PK Series	0.6mm, 0.63mm, 1.5mm	<2mm – 10mm	Stickers, vinyl, folding cartons, PP paper

Common IECHO Blade Models & Dimensions
Manufacturers like Oyea Machinery provide standardized blades for these systems:
E1 / E2 (Drag Knife): Ø3 x 18.5mm round-stock blades with a 35° angle, used in Kiss-Cut Tools (KCT) for vinyl and thin paper.

E16 / E17 (General Drag/Oscillating): ~25mm height, 5.6mm width, and 1.5mm thickness. E17 is a long-life version for deeper cuts up to 12mm.

E21 / E28 (Oscillating): 0.63mm thickness with varied lengths (28mm to 38mm) for EOT and POT tools, cutting depths up to 26mm.

E64 (Pneumatic): Heavy-duty 1.5mm thick blades for POT, capable of cutting depths up to 57mm in materials like heavy foam.

E50 / E51 / E52 (Rotary): Circular blades (Ø25mm to Ø32mm) with 0.63mm thickness for Driven Rotary Tools (DRT) used in textiles.

E19-10 / E19-11 (V-Cut): Specialized blades for grooving cardboard and sandwich boards at specific angles (0° to 45°).

Material-Specific Recommendations
Thin Materials (Vinyl/Paper): Use thinner 0.5mm–1.0mm blades with acute angles (e.g., E1, E2) to reduce drag.
Soft/Thick Materials (Foam/Rubber): Use oscillating blades with large angles (e.g., E18L, E63) to prevent material distortion.
Hard/Rigid Materials (ABS/Acrylic): Require tungsten carbide or coated blades (e.g., E21, E66) for wear resistance.
