Graphtec CB15U-K30 Super-Steel Blade 60° 1.5mm | 5-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 sandblast rubber resist media, high-intensity reflective sheeting, and rigid media 0.25mm to 0.5mm thick. This listing is the CB15U-K30-5 pack — 5 blades per pack at the best per-blade value for high-volume sandblast and reflective sheeting operations. The CB15U-K30 has no spring on the blade — install directly into the PHP35-CB15-HS holder without removing a spring. Every CB15U-K30 we sell at Digiprint USA is 100% genuine Graphtec.

Product Details

Pack Size Options — 2-Pack vs 5-Pack

USA 60° vs Japan 30° — Naming Convention Explained

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

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

The CB15U-K30 is labelled 60° in US documentation and 30° in Japanese documentation — it is the same physical blade. If you are ordering from a Japanese Graphtec service manual and see "CB15U-K30 30°", this listing is the correct product.

CB15U-K30 vs CB15UA-K30 — Spring vs No Spring

Both blades are identical in cutting performance. For high-volume operations the CB15U-K30 (no spring) is the simpler choice — no spring removal step needed on every blade change.

Applications

• Sandblast rubber resist media — 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

What is the difference between CB15U-K30-5 and CB15U-K30-2?
Both contain the same genuine Graphtec CB15U-K30 60° / 1.5mm blade. The CB15U-K30-2 is a 2-blade pack at $119.00 ($59.50 per blade). The CB15U-K30-5 is a 5-blade pack at $279.50 ($55.90 per blade). For regular sandblast or reflective sheeting production the 5-pack reduces cost per blade and minimises reorder frequency.

What is the difference between CB15U-K30 and CB15UA-K30?
The CB15U-K30 has no spring on the blade — install directly into the PHP35-CB15-HS holder. The CB15UA-K30 has a spring attached — you must remove it before installing in the same holder. Both cut identically. For high-volume use the CB15U-K30 (no spring) saves the spring removal step on every blade change.

Why does the CB15U-K30 show 60° in the USA but 30° in Japan?
Different regional conventions. US documentation measures the full included blade tip angle (60°). Japanese documentation measures the half-angle from the centreline (30°). Same blade — if your Japanese service manual shows "CB15U-K30 30°" this is the correct product.

What blade holder does the CB15U-K30 require?
The PHP35-CB15-HS — 1.5mm blade holder, red top, brass tip. The CB15U-K30 has no spring so it installs directly without preparation. Do not use the 0.9mm PHP33-CB09N-HS holder — blade diameter must match the holder.

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 and sandblast engravers using freight forwarders in the Doral area.
