GRS C-Max #4 Onglette Carbide Graver – 2.4 mm
The GRS C-Max #4 Onglette Carbide Graver is a precision, pre-shaped tungsten carbide engraving tool designed for hand engraving, jewelry engraving, stone setting, inlay work, border cutting, and variable-width line engraving. With a 2.4 mm #4 Onglette profile, this graver provides a versatile pointed cutting geometry for both decorative and precision metalworking applications.
The C-Max Onglette features angled sides that taper toward a pointed cutting edge, allowing the engraver to create controlled lines and varying widths by changing the angle and position of the tool. Its factory-shaped profile saves preparation time compared with creating an Onglette from a blank.
Manufactured from special tungsten carbide, C-Max gravers are designed to provide a balance of hardness and toughness for demanding hand engraving and stone-setting applications.

What Is an Onglette Graver?
An Onglette graver has angled sides that taper toward a narrow, pointed cutting edge. This distinctive geometry makes it especially useful when an engraver needs to create flowing lines, borders, inlay channels, and cuts with varying widths.
The GRS C-Max Onglette combines this versatile profile with a specialized tungsten carbide material developed for hand engraving and stone-setting applications.
C-Max Carbide Performance
GRS developed C-Max carbide to provide engravers and stone setters with a tool material that balances hardness and toughness. The result is a precision carbide graver designed to maintain a fine cutting edge while providing the durability required for demanding professional work.
The C-Max Onglette series is available in multiple sizes, allowing engravers to select the tool-point width that best matches the desired cut and level of detail. The #4 / 2.4 mm size offers a useful option for medium-width engraving and detailed stone-setting work.
QC Tool Holder Compatibility
The #4 C-Max Onglette has a 1/8-inch (3.175 mm) round shank with two flat alignment areas. These flats allow the set screws in a GRS QC Tool Holder to orient and secure the graver consistently.
