Built for weld cleanup, edge preparation, and controlled material removal with compact abrasive wheels, the Cleco C3135A4-38OH Right Angle Grinder pairs a 1.7 HP pneumatic motor with 13,500 RPM free speed for fast grinding on fabricated metal parts, repair components, and production assemblies. The 4" wheel capacity helps operators work in tighter areas than larger 5" grinders, while the 3/8"-24 spindle thread supports compatible Type 27, Type 27 threaded hub, and Type 1 abrasive discs when the wheel type and speed rating are properly matched.
The 3.03" head height gives this C31 Series grinder useful access around brackets, weldments, corners, and part geometry where clearance matters. Its rear exhaust overhose routes spent air away from the grinding area, helping reduce debris disturbance near the wheel contact point. A quick-change spindle lock, anti-vibration handle, dual-layer composite housing, and 270° adjustable guard make the tool practical for repeated abrasive changes and daily grinding work in fabrication, maintenance, and repair environments.

Applications:
- Metal fabrication: Grinding weld beads, smoothing cut edges, and preparing steel components before finishing or coating.
- Welding and repair shops: Removing spatter, blending small welds, and cleaning joint areas with compatible 4" abrasive wheels.
- Industrial maintenance and MRO: Deburring machinery parts, removing corrosion, and cleaning repaired components during rebuild work.
- Transportation and equipment service: Grinding brackets, frame sections, panels, and fabricated assemblies where a smaller wheel improves access.
- Production workstations: Repeated edge cleanup and surface preparation where pneumatic power, rear exhaust, and fast abrasive changes support consistent workflow.
FAQs:
- Q: What wheel size does the Cleco C3135A4-38OH use?
A: This model is configured for 4" abrasive wheels. Always confirm that the wheel type, spindle thread, guard, and maximum operating speed are compatible before mounting an accessory. - Q: What does the 3/8"-24 spindle thread mean?
A: The spindle thread identifies the threaded connection used to mount compatible abrasive hardware or threaded-hub discs. Accessories must match the 3/8"-24 thread and be approved for the grinder’s operating speed. - Q: Why choose this 4" model instead of a 5" grinder?
A: A 4" grinder can be easier to position around smaller parts, weldments, brackets, and tight work areas. A 5" grinder may cover more surface area, but this model offers better access where clearance is limited. - Q: What is rear exhaust overhose?
A: Rear exhaust overhose means spent air is directed through the rear of the tool and away from the grinding area. This can help reduce air blast near the abrasive contact point and improve work-area control. - Q: What air hose should be used with this grinder?
A: The listed minimum hose I.D. is 1/2". Using hose that is too small can restrict airflow and reduce performance, especially during continuous grinding.
