Graphtec 15U Blade for 30° Plotter Cutting
A Graphtec 15U blade with a 30-degree angle is intended for compatible cutting plotters and holders that accept the CB15-style 1.5 mm shank. The listed dimensions are a 1.5 mm diameter and an 18 mm overall length, with a 0.25 mm offset. Buyers should compare these specifications with the installed holder and machine documentation before ordering.
JEEFOO supplies plotter cutting tools from Guangzhou, China. Provide the Graphtec model, holder type, media, thickness, and cutting application for a practical compatibility comparison.

The original thickness line is damaged and combines more than one value, so it should not be treated as a verified cutting-capacity claim. Confirm the suitable media thickness with the plotter and holder specifications. Actual results also depend on blade exposure, force, speed, offset, holder condition, and material construction.
What Is a 30-Degree CB15 Plotter Knife Used For?
A 30-degree blade uses a shallower cutting angle that may suit thin vinyl, labels, lettering, masking film, and other routine contour-cutting work when the machine and holder support the CB15 format. The 1.5 mm shank distinguishes this blade from smaller CB09-style options. These formats should not be treated as interchangeable.
If corners remain connected or small letters lift, inspect the tip and holder before increasing force. Adhesive residue can restrict blade rotation, while a worn or chipped tip can produce incomplete cuts. Excessive force may score the backing liner or damage the cutting strip.
How to Confirm Compatibility
Identify the exact Graphtec cutter model and holder reference. Compare the current blade’s shank diameter, length, angle, and offset with the listed values. Review the machine manual for supported blade types. A matching angle alone is not enough if the shank diameter or holder design differs.
For related hardware, see the Graphtec plotter blade holder. You can also compare the cutting plotter blade range. For current machine information, consult the official Graphtec America cutting plotter pages.
Test-Cut Setup Checklist
- Clean the holder and verify that the blade rotates freely.
- Confirm that the holder accepts a 1.5 mm CB15-style shank.
- Insert the blade without forcing the shank.
- Expose only enough tip to cut the face material.
- Begin with conservative force and speed settings.
- Run a small test pattern containing lines, curves, and corners.
- Inspect weedability and check the backing liner for deep marks.
- Adjust one setting at a time and repeat the test.
Blade exposure is a mechanical limit, while downforce is a machine setting. Too much exposed tip cannot be corrected simply by reducing force. A controlled test helps protect the blade, holder, and cutting strip while identifying suitable settings for each material.
Care and Replacement
Store unused blades dry and protected so their tips do not touch hard surfaces. Remove dust and adhesive residue from the holder. Replace a worn or chipped blade instead of continually increasing force. Record successful settings for each media so later jobs can begin from a known baseline.
Ordering from JEEFOO in Guangzhou, China
When requesting a Graphtec 15U blade, include the machine model, holder type, 1.5 mm shank requirement, 30-degree angle, material, thickness, and intended application. JEEFOO can compare those details with the listed product specifications for lettering, labels, decals, sign vinyl, and compatible contour-cutting workflows.
