## Long description

Proxxon 28920 Engraver Bit Proxxon 28920 Metal 4 pcs is a set of four metal grinding and engraving bits designed for precision work on glass and other hard materials. The set contains two diamond ball bits and two silicon carbide bits in cone and bullet shapes. All bits have a 2.35 mm shaft diameter for compatibility with standard rotary tools and engravers.
Advantages
The diamond bits provide fine, wear-resistant cutting edges for precise engraving and detailed frosting on glass. Silicon carbide bits offer aggressive material removal for shaping and smoothing edges. The variety of shapes — small and larger ball heads plus cone and bullet profiles — allows versatile use for different engraving depths and surface finishes. Shafts with Ø 2.35 mm ensure secure fit in most handheld rotary tools.

How to use
Mount the chosen bit securely in the collet or chuck of a compatible rotary tool supporting a 2.35 mm shaft. Start at low speed to locate the working point and increase speed as required for the material and desired finish. Use steady, light pressure and allow the bit to do the cutting; avoid overheating the workpiece. For glass frosting or delicate engraving, use the diamond ball bits; for faster material removal or shaping use the silicon carbide cone or bullet bit.
Usage recommendations
Wear appropriate eye protection and a dust mask when working. Secure the workpiece and work in a well-ventilated area. Periodically cool bits when engraving glass to prevent thermal stress; replace worn bits to maintain precision.
