Cleco 4060AVL-09 Vertical Grinder | 4060 Series | Aluminum Housing | 4.0 HP | 6,000 RPM | Side Exhaust

Built for broad-surface grinding and high-rate metal removal, the Cleco 4060AVL-09 Vertical Grinder delivers 4.0 HP / 3.1 kW of pneumatic power with a 6,000 RPM free speed for running 9" Type 27 abrasive wheels. A vertical grinder places the motor above the wheel, giving operators steady downward control when removing weld buildup, scale, casting flash, and excess material from larger metal parts.

Part of Cleco’s 4060 Series, the 4060AVL-09 uses an aluminum housing, side exhaust, and a 5/8"-11 external thread spindle for common industrial grinding wheel mounting. Cleco rates the tool at 90 PSI / 620 kPa and specifies a 3/4" / 19 mm minimum hose I.D., which helps the grinder receive enough air volume to maintain speed during demanding grinding passes.

Applications:

• Heavy metal fabrication — grinding weld seams, removing excess bead material, and preparing plate or structural components for finishing.
• Foundry and casting cleanup — removing flash, gates, risers, and rough surface defects when paired with the correct Type 27 wheel.
• Industrial maintenance and MRO — resurfacing worn parts, cleaning repaired components, and preparing metal surfaces before rework or coating.
• Shipyard and rail repair — removing weld buildup, scale, and surface imperfections from large fabricated structures and repair sections.
• Heavy equipment rebuild work — grinding frames, buckets, brackets, guards, and welded repair areas on machinery and attachments.

FAQs:

• Q: What abrasive wheel does the Cleco 4060AVL-09 use?
  A: This model is specified for 9" Type 27 abrasive wheels. Always confirm that the wheel, guard, spindle thread, and maximum RPM rating are compatible before use.
• Q: What does Type 27 mean on this grinder?
  A: Type 27 refers to a flaring cup wheel shape used for surface grinding and material removal. It is different from depressed-center Type 27 wheels, so the correct abrasive type should be selected for this tool.
• Q: What air hose size is required?
  A: Cleco specifies a 3/4" / 19 mm minimum hose I.D. for the 4060 Series vertical grinders. Using a smaller hose can restrict airflow and reduce the grinder’s ability to hold speed under load.
• Q: Does the 4060AVL-09 include the grinding wheel?
  A: The standard equipment list includes the wheel guard, adapters, spindle wrenches, operating instructions, and service manuals. Abrasive wheels should be selected separately based on material, wheel type, and speed rating.
• Q: Is this grinder appropriate for light deburring or small garage work?
  A: The 4060AVL-09 is a high-power vertical grinder intended for larger metal removal jobs. For light deburring, small automotive work, or tight access areas, a die grinder or smaller angle grinder may be a better choice.
