Ingersoll Rand EP51K Pneumatic Air Engraving Pen Kit | 13,000 BPM | 7/32" Hose Size | Steel Material

For detailed part identification, surface marking, and precision engraving, the Ingersoll Rand EP51K Inline Air Engraving Pen Kit delivers controlled pneumatic marking performance across a variety of materials. Operating at 13,000 blows per minute (BPM), the EP51 engraving pen produces rapid impacts through a carbide-tipped stylus to create markings on surfaces ranging from brittle ceramics to hard metal alloys. Its inline, pencil-style configuration provides a comfortable gripping position for detailed engraving, while the knurled variable zoom throttle acts as a regulator, allowing operators to adjust engraving intensity according to the material and application. The kit includes three assorted carbide-tipped styluses (fine, medium, and coarse), providing different tip configurations for fine detail and material-specific marking requirements.

The Ingersoll Rand EP51K features a durable steel housing that withstands industrial working conditions while helping dampen vibration during engraving. Its 5.6-inch (142 mm) overall length and 0.31 lb (0.14 kg) weight make the tool convenient to handle when marking small components, intricate surfaces, and identification details. With an air consumption of 1.5 CFM (42.5 L/min), the engraving pen has relatively low compressed-air demand. The 1/8-inch NPT air inlet and 7/32-inch (6 mm) minimum hose size provide the connection specifications needed for air supply planning. Supplied with a 6-foot (183 cm) flexible hose and molded plastic carrying case, the EP51K provides an organized engraving solution for manufacturing, fabrication, maintenance, and precision workshop applications.

FAQs:

• Q: What materials can the Ingersoll Rand EP51K engraving pen mark?
  A: Ingersoll Rand specifies engraving capabilities across a variety of materials, ranging from brittle ceramics to hard alloys. The three carbide-tipped styluses allow operators to select different tip configurations according to the material and marking requirements. Test the selected stylus and engraving intensity on a sample or noncritical area before marking finished components.
• Q: What is the difference between the fine, medium, and coarse styluses?
  A: The EP51K includes three carbide-tipped styluses with different tip configurations. These provide flexibility for different engraving details and workpiece materials. The manufacturer does not specify a fixed engraving depth for each stylus, so actual marking depth will depend on factors such as material properties, throttle adjustment, and operating technique.
• Q: Can the engraving intensity be adjusted on the EP51K?
  A: Yes. The engraving pen features a knurled variable slide/zoom throttle that acts as a regulator. This provides greater control over the engraving action when working with different materials and marking requirements.
• Q: How much compressed air does the Ingersoll Rand EP51K require?
  A: The EP51 engraving pen has a manufacturer-specified air consumption of 1.5 CFM (42.5 L/min). It uses a 1/8-inch NPT air inlet and requires a minimum hose size of 7/32 inch (6 mm). The air supply must also meet the operating pressure requirements stated in the manufacturer's instructions.
• Q: What is included in the EP51K kit compared with the EP51 engraving pen?
  A: The EP51K is the kit configuration containing the EP51 engraving pen, three styluses (fine, medium, and coarse), a flexible air hose, and a molded plastic carrying case. The EP51 is the individual engraving pen model, while the EP51K provides the additional accessories listed by the manufacturer.
