Graphtec CB15U-K30 Super-Steel Blade 60° 1.5mm | 2-Pack FC FCX

The Graphtec CB15U-K30 is a genuine original super-steel cutting blade with a 60° cutting angle (USA designation) and 1.5mm diameter — engineered for cutting rigid media 0.25mm to 0.5mm thick, small detailed characters on marking film, sandblast rubber resist media, and high-intensity reflective sheeting. This is a specialist blade for demanding applications that standard 45° blades cannot handle cleanly. This listing is the CB15U-K30-2 pack — 2 blades per pack. Every CB15U-K30 we sell at Digiprint USA is 100% genuine Graphtec.

Product Details

USA 60° vs Japan 30° — Understanding the Naming Convention

This is a common source of confusion for Graphtec users. The CB15U-K30 is labelled 60° in the USA and 30° in Japan — but it is the same physical blade. Graphtec's US and Japanese documentation use different conventions for measuring blade angle:

• USA convention: measures the full included angle of the blade tip — 60°

• Japan convention: measures the half-angle from the blade centreline — 30°

If you are ordering from a Japanese Graphtec catalogue or service manual and see "30°", this is the same blade as the CB15U-K30 listed here. If your US documentation says "60°", same blade. Contact our team if you need help confirming the correct part number for your region.

CB15U-K30 60° vs CB15UA 45° — Which Do You Need?

Both use the PHP35-CB15-HS 1.5mm blade holder. The 60° blade produces a narrower, sharper cutting edge suited for detail work and abrasive materials like sandblast resist. The 45° blade is better for laminates and protective films. Contact our team if you are unsure which angle is correct for your application.

Applications

• Sandblast rubber resist media — the primary recommended application; clean cuts through thick rubber masking without tearing or dragging

• High-intensity reflective sheeting (ASTM Type IV and above) — precise cutting of demanding reflective materials for safety signage

• Rigid self-adhesive media 0.25mm to 0.5mm — thick specialty media requiring a more acute blade angle for clean edge definition

• Small detailed characters on marking film — fine detail work on marking film up to 0.25mm where a narrower blade edge is required

• Thick vinyl requiring acute angle — any application where the standard 45° blade produces ragged edges or excessive wear

When to Replace

Replace CB15U-K30 when you notice:

• Ragged or torn edges on sandblast resist or reflective sheeting

• Loss of fine detail in small character cutting

• Visible tip chipping or deformation under magnification

• Increased cutting force required to maintain the same cut quality

Frequently Asked Questions

Why does the CB15U-K30 show 60° in the USA but 30° in Japan?
Graphtec uses different regional conventions for measuring blade angle. The USA specification measures the full included angle (60°), while the Japanese specification measures the half-angle from the blade centreline (30°). The CB15U-K30 is the same physical blade regardless of which convention your documentation uses. If you are ordering from a Japanese service manual and see "CB15U-K30 30°", this is the correct blade.

What is sandblast rubber resist media and why does it need a 60° blade?
Sandblast rubber resist is a thick, flexible rubber sheeting used as a masking material in sandblast engraving on glass, stone, and metal. It is significantly thicker and more abrasive than standard vinyl. The 60° blade angle produces a narrower, sharper cutting edge that cuts cleanly through this material without tearing or dragging. The standard 45° blade will wear quickly and produce ragged edges on rubber resist media.

What blade holder does the CB15U-K30 require?
The CB15U-K30 uses the PHP35-CB15-HS — the 1.5mm blade holder with red top and brass tip. This is the same holder used for the CB15UA 45° blade. Blade diameter must always match the holder diameter.

Is the CB15U-K30 compatible with CE series Graphtec cutters?
No — the CB15U-K30 is listed for FC and FCX series only. If you have a CE series cutter and need to cut sandblast resist or reflective sheeting, contact our team to confirm the correct blade for your specific model.

Do you ship Graphtec blades to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Our Miami location is ideal for Latin American sign shops, sandblast engravers, and wide-format businesses using freight forwarders in the Doral area.
