THANMAO CB09U Blade Holder Kit for Silhouette & Graphtec — 30 Carbide Blades (30/45/60°), Spring-Free Base

THANMAO CB09 CB09U blade holder kit includes a durable stainless-steel holder plus 30 carbide-tipped replacement blades (10 each: 30°, 45°, 60°) designed for precise cutting on Silhouette Cameo, Portrait, Curio and Graphtec plotters.

This kit pairs a redesigned spring-free holder base with high-hardness tungsten carbide blades to deliver sharper edges, longer wear and easier installation. The three blade angles cover delicate, general-purpose and heavy-duty cutting tasks so you can switch quickly between vinyl signage, fine lettering and thicker reflective or masking materials. All parts fit CB09/CB09U-style housings and are intended for manual blade-depth adjustment in compatible machines.

Which blade angle should I choose for delicate lettering and tiny shapes?

Use the 30° blades (yellow cap) for the smallest fonts, intricate line-art and fine detail where a narrow cutting face prevents tearing or overcutting. These blades excel at tracking tight curves and narrow gaps in thin materials.

• 30° (yellow cap): best for very small fonts and delicate vinyl
• Material examples: thin adhesive vinyl, fine heat-transfer film
• Blade size: 20mm x 1mm carbide tip for accuracy

How do the 45° blades perform for everyday vinyl and sign work?

The 45° blades (red cap) are the go-to option for general cutting tasks—balancing sharpness and durability for most vinyl films and common craft materials. They provide reliable results for standard lettering, decals and many sign-making applications when set to the correct blade depth.

• 45° (red cap): general-purpose cutting for vinyl and flock
• Good for traffic signage vinyl, heat-transfer, cardstock
• Adjust blade depth manually for consistent cuts on different media

Can these blades handle thick or reflective materials?

The 60° blades (blue cap) have a wider shear angle suited to cutting thicker, tougher materials up to about 1 mm. They concentrate force into a stronger cutting edge, making them more effective for reflective sheeting, masking tape and heavy vinyl.

• 60° (blue cap): designed for thick materials and large fonts
• Works well on reflective material, heavy masking tape and thicker vinyl
• Carbide (HRA93) tips deliver greater hardness and prolonged edge life

How easy is installation and compatibility with my plotter?

The holder base is upgraded for spring-free installation—open the base, place the blade into the angled hole (black side), replace its cover and tighten. This kit is compatible with Silhouette Cameo 1–4, Portrait, Curio and Graphtec 6000/CE5000 series that accept CB09-style holders, but blade depth must be set manually on the machine.

• Includes 1 stainless-steel holder and 30 carbide blades (10 per angle)
• Installation: remove cover, insert blade, re-tighten—no spring needed
• Manual blade-depth adjustment required on Silhouette/Graphtec machines

Features at a glance: the blades are tungsten-carbide for ultra hardness and fine-polished edges, the holder dimensions (52mm x 11mm) match CB09/CB09U form factors, and blade dimensions are 20mm x 1mm for predictable fit. The colour-coded caps make angle selection fast: yellow for 30°, red for 45° and blue for 60°. This bundle supplies extra blades so you can swap angles without hunting for replacements mid-project.

Who is this for? If you produce decals, custom apparel transfers, signage, paper crafts or any precision-cut artwork, this THANMAO kit gives a ready supply of three blade geometries and a robust holder for frequent swapping. It’s ideal for hobbyists, small print shops and design studios that use Silhouette or Graphtec cutters and need sharper, longer‑lasting carbide tips to handle a variety of media while retaining control over cut depth and pressure.
