Graphtec CB15UA Super-Steel Blade 45° 1.5mm 5-Pack

The Graphtec CB15UA Super-Steel Blade (45° / 1.5mm, part number CB15UA-5, 5-pack) is the genuine original Graphtec replacement blade for cutting high-intensity reflective film, laminates, and device screen protection media on FC, FCX, and CE series cutting plotters. With a 45° cutting angle and 1.5mm diameter, the CB15UA is designed for rigid or thicker media in the 0.25mm–0.5mm thickness range — and its Super-Steel alloy formulation is specifically hardened for the abrasive metalized and retroreflective layers found in high-intensity and diamond-grade reflective sheeting that dulls standard blades prematurely. Every CB15UA we stock at Digiprint USA is 100% genuine original Graphtec — not aftermarket, not compatible.

CB15UA is not the same as CB15U — confirm before ordering. Both blades are 45° / 1.5mm but they differ in steel formulation and primary application. The CB15UA (this listing) uses a harder Super-Steel alloy optimised for high-intensity reflective film, laminates, and screen protection media. The CB15U is the standard 45° / 1.5mm blade for general rigid media 0.25–0.5mm thick. For sandblast rubber and thicker rigid media up to 1.5mm, use the CB15UA-K30 (60° blade — sold separately). Check your Graphtec application chart or existing blade label before ordering.

Requires a 1.5mm blade holder (red tip) — not included. The CB15UA uses the PHP33-CB15N-HS (red tip, plastic) or PHP35-CB15-HS (red top, brass tip) blade holder. It is not compatible with the standard 0.9mm blue/black blade holder supplied with most FC and CE machines. If switching from a 0.9mm to a 1.5mm blade, the correct holder must be installed first. If using the PHP35-CB15-HS brass tip holder, remove the blade spring before installation.

Graphtec 1.5mm Blade Selection Guide

All four main CB15 blade variants use the same 1.5mm diameter and the same red-tip blade holders. The differences are cutting angle and steel formulation — matching the blade to the media is essential for clean cuts and blade longevity:

Blade	Angle	Thickness	Best For
CB15U	45°	0.25–0.5mm	General rigid media — laminates, thick vinyl, screen protection
CB15UA (this listing)	45°	0.25–0.5mm	High-intensity reflective film, laminates, screen protection — hardened alloy
CB15U-K30	60°	0.5–1.5mm	Sandblast rubber resist, thick rigid media, HI reflective
CB15UA-K30	60°	0.25–1.5mm	Diamond grade, prismatic, HI reflective, sandblast — hardened alloy

How to Identify Your Blade Holder Size — The Colour Guide

Graphtec colour-codes its blade holders by blade diameter. If you are unsure which holder you have installed, check the tip colour: a blue or black tip holder = 0.9mm blades (CB09 series — the standard holder shipped with most FC and CE machines); a red tip holder = 1.5mm blades (CB15 series — required for CB15UA). Installing a 1.5mm CB15UA blade into a 0.9mm holder will not seat correctly and will damage the holder. If you are switching from 0.9mm standard vinyl cutting to reflective media, you need to change the blade holder to PHP33-CB15N-HS or PHP35-CB15-HS before installing the CB15UA.

When to Replace Your CB15UA Blade

Replace the CB15UA when you notice:

• Tearing or lifting of the reflective film layer instead of a clean cut edge

• Incomplete cuts despite correct blade force settings — a dull tip no longer penetrates cleanly

• Visible tip chipping or deformation when examined under magnification

• Increased blade force settings required to achieve the same cut quality as before

• Excessive media lifting or peeling on contour cuts around fine details

For high-intensity reflective film, which is more abrasive than standard vinyl, blade life is shorter than standard media — the 5-pack CB15UA-5 is the recommended stock unit to keep a ready supply without per-blade premium pricing.

Applications

• High-intensity reflective film — traffic signage, safety markings, vehicle conspicuity tape, fleet identification decals

• Retroreflective and engineer-grade sheeting — road signage and industrial safety graphics

• Laminates and overlaminate — cutting laminated print output for print-and-cut and contour cut finishing

• Screen protection film — precision die-cutting of device screen protectors and custom protection templates

• Specialty media 0.25–0.5mm — any rigid or semi-rigid film or sheet that exceeds the capability of standard 0.9mm blades

Frequently Asked Questions

What is the difference between CB15UA and CB15U?
Both are 45° / 1.5mm Super-Steel blades for rigid media 0.25–0.5mm thick, but they use different steel formulations. The CB15UA uses a harder alloy specifically engineered for the abrasive metalized and retroreflective layers in high-intensity reflective film, laminates, and screen protection media. The CB15U is the standard formulation for general rigid thick media. For reflective and laminate applications, the CB15UA lasts significantly longer before dulling. Using a CB15U on reflective film will work but will dull faster — the CB15UA is the correct blade for this application.

Which blade holder does the CB15UA use?
The CB15UA requires a 1.5mm red-tip blade holder — either PHP33-CB15N-HS (plastic tip, standard) or PHP35-CB15-HS (brass tip, more rigid for precision cuts). It is not compatible with the standard 0.9mm blue/black blade holders shipped with most FC and CE machines. If your holder has a blue or black tip, you need to purchase the correct 1.5mm red-tip holder before using CB15UA blades.

Do I need to remove the spring when using CB15UA with the PHP35-CB15-HS brass tip holder?
Yes. The PHP35-CB15-HS brass tip holder requires blade spring removal before installation. The spring is not compatible with the brass tip holder design — installing the blade with the spring in place in the PHP35 will cause incorrect blade protrusion and potential holder damage. The PHP33-CB15N-HS plastic tip holder uses the standard spring configuration.

When should I use CB15UA-K30 instead of CB15UA?
Use the CB15UA-K30 (60° blade, sold separately) for media thicker than 0.5mm — including sandblast rubber resist, diamond-grade reflective, prismatic sheeting, and other thick rigid materials up to 1.5mm. The CB15UA (this listing, 45°) is for the 0.25–0.5mm range. For the thicker media range, the steeper 60° angle of the K30 variant provides the longer cutting edge geometry needed to penetrate cleanly without deflecting.

Do you ship Graphtec CB15UA blades to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Our location is ideal for Latin American sign shops, reflective media specialists, and vehicle graphics producers using freight forwarders in the Doral area.
