Ingersoll Rand EP51 Pneumatic Air Engraving Pen | 13,000 BPM | 7/32" Hose Size | Steel Material

For permanent part identification, detailed lettering, and precision surface marking, the Ingersoll Rand EP51 Inline Air Engraving Pen delivers controlled pneumatic engraving in a compact, pencil-style configuration. Operating at 13,000 blows per minute (BPM), the EP51 uses rapid percussive impacts to create fine markings on various materials, from brittle ceramics to hard metal alloys. Its inline configuration and narrow pencil-style neck allow operators to guide the engraving tip around small components, detailed markings, and irregular surfaces. A knurled variable zoom throttle acts as a regulator, allowing the operator to adjust engraving intensity according to the material and marking requirements. The EP51 supports fine, medium, and coarse carbide-tipped styluses for different engraving applications.

Constructed with a durable steel housing, the Ingersoll Rand EP51 is built for industrial engraving operations while helping dampen vibration during use. Its compact 5.6-inch (142 mm) overall length and lightweight 0.31 lb (0.14 kg) construction make it convenient to maneuver when working on smaller metal parts, tooling, and intricate surfaces. With an air consumption of 1.5 CFM (42.5 L/min), the engraving pen has modest compressed-air requirements for workshop use. The 1/8-inch NPT air inlet and 7/32-inch minimum hose size help buyers select the appropriate air connection. Combining variable engraving control with a comfortable gripping profile, the EP51 is a practical marking tool for metal fabrication, manufacturing, tool and die work, and industrial maintenance applications.

• Precision workshops: Creating detailed markings on suitable specialty materials, including ceramics and hard alloys, with the appropriate stylus and engraving intensity.

FAQs:

• Q: What materials can the Ingersoll Rand EP51 engraving pen mark?
  A: The EP51 is intended for engraving a variety of materials, ranging from brittle ceramics to hard metal alloys. The appropriate stylus and throttle setting depend on the workpiece material and required marking detail. Test the engraving action on a sample or noncritical surface before marking finished components.
• Q: What is the purpose of the fine, medium, and coarse styluses?
  A: Ingersoll Rand identifies three carbide-tipped stylus configurations: fine, medium, and coarse. These provide different tip options for various materials and engraving details. The manufacturer does not specify an exact engraving depth for each stylus, so marking depth should not be determined by tip designation alone.
• Q: How much compressed air does the EP51 require?
  A: The manufacturer specifies air consumption of 1.5 CFM (42.5 L/min), a 1/8-inch NPT air inlet, and a 7/32-inch minimum hose size. The compressed-air supply must also meet the operating pressure and air preparation requirements in the manufacturer's instructions.
• Q: Can the engraving intensity be adjusted?
  A: Yes. The EP51 features a knurled variable slide/zoom throttle that acts as a regulator for the engraving action. This allows the operator to adjust the tool response when working with different materials and marking requirements.
• Q: What is the difference between the Ingersoll Rand EP51 and EP51K?
  A: The EP51 is the individual air engraving pen model, while the EP51K is the kit configuration. The EP51K includes the EP51 engraving pen, three carbide-tipped styluses (fine, medium, and coarse), a flexible hose, and a molded plastic carrying case. Buyers needing the complete accessory package should select the EP51K.
