GRS 022-452 #52 QC HSS Round Graver – 0.6 mm

The GRS 022-452 #52 QC HSS Round Graver is a precision 0.6 mm Quick Change (QC) round graver designed for professional hand engraving, jewelry engraving, bead raising, block lettering, line engraving, and engraving on uneven or contoured surfaces.

The round graver features a wider flat top, narrower rounded bottom, and angled flat sides, creating a specialized cutting profile that provides a controlled, rounded cutting edge. This geometry makes the 022-452 particularly useful for engraving applications where a conventional flat or square graver may not provide the desired cutting action.

Made from high-speed chrome tool steel, the 022-452 provides the durability and edge retention required for professional engraving. Its factory-shaped tip and QC shank save preparation time and allow quick tool changes when used with a compatible GRS QC holder.

At 0.6 mm, the #52 is a fine round graver suited to detailed work while still providing a rounded cutting edge for distinctive engraving effects.

The GRS 2026 catalog identifies #52 / 022-452 as the 0.6 mm QC Round Graver. The cutting-edge measurement is taken across the diameter of the cutting edge.

Precision Round Graver Profile

The GRS QC Round Graver has a specialized profile designed around a rounded cutting edge. The 022-452 features a wider flat top, narrower rounded bottom, and flat sides that angle downward.

This geometry gives the engraver a different cutting characteristic from a flat, square, or onglette graver. The rounded edge is particularly useful when a smooth, controlled cut is desired or when working across uneven surfaces.

Ideal for Bead Raising

The 022-452 is specifically designed for bead raising, where controlled cutting is used to create or define raised bead-like details in metal.

The 0.6 mm cutting edge provides a fine profile for detailed bead work and small decorative elements.

Block Lettering & Line Engraving

The #52 round graver is also well suited for block lettering and line engraving. Its rounded cutting edge produces a different visual character from a flat graver and can be useful for creating smooth, controlled cuts in lettering and decorative designs.

At 0.6 mm, it provides a useful balance of precision and cutting capacity for fine engraving work.

Engraving Uneven & Curved Surfaces

One of the key advantages of the round profile is its suitability for engraving on uneven, curved, or irregular surfaces.

The rounded cutting edge can help maintain controlled contact with the workpiece where a wider flat graver may be more difficult to maneuver. This makes the 022-452 a useful specialty tool for three-dimensional and contoured engraving projects.

High-Speed Chrome Tool Steel

The 022-452 is made from high-speed chrome tool steel, a durable material selected for professional engraving applications.

The HSS construction provides hardness and wear resistance for maintaining a sharp cutting edge when the graver is properly sharpened and maintained.

Factory-Shaped for Faster Preparation

The GRS QC Round series uses factory-shaped tips, helping eliminate the initial shaping process required with raw graver blanks. This allows the engraver to move more quickly to final sharpening and application-specific tool preparation.

The 022-452 can still be sharpened and prepared according to the engraver's preferred face, heel, and cutting geometry.

Quick Change Compatibility

The integrated GRS Quick Change shank is designed for use with compatible QC holders.

For the 022-452, Micro-Tools specifies the GRS QC Tool Holder for 3/32" Round (#004-853). This holder is sold separately.

The QC system makes switching between different graver profiles and sizes faster and more convenient during engraving projects.
