EDM Ceramic Guides

Guide Types

Standard Guides

Guides with inner diameters from .20 mm to 6.0 mm are available as standard guides. These guides are robust, with a thick body and blunt tip, and have a longer lifespan than micro guides.

Micro Guides

Guides with inner diameters from .10 mm to .29 mm are available as micro guides. The slim profile and tapered tip allow for more accurate drilling.

L-Type Guides

These guides have a very thin body, and are perfect for getting into tight spaces. L-Type guides with conventional ceramic guiding surfaces are available in inner diameters from .30 mm to 1.0 mm. If you require a guide with different dimensional characteristics, please refer to our custom guides page.
