Cleco 236GLR-115A-D3T4 Heavy Duty Head Right Angle Grinder | 236 Series | 0.9 HP | 11,500 RPM | Aluminum Housing | Rear Exhaust

Built for weld cleanup, edge dressing, and controlled metal removal, the Cleco 236GLR-115A-D3T4 Heavy Duty Head Right Angle Grinder delivers 0.9 HP of pneumatic power with 11,500 RPM free speed for use with 4" Type 27 depressed-center grinding wheels. The right-angle head helps the operator keep the wheel flat against welds, plate edges, brackets, and fabricated assemblies, while the rear exhaust directs spent air away from the work surface.

Part of the Cleco 236 Series, this grinder is built with an aluminum housing and heavy duty head configuration for repeated grinding work in fabrication shops, MRO departments, repair bays, and production environments. The 3/8"-24 external spindle thread supports the D3T4 Type 27 wheel setup, making this model a practical choice when a 4" grinding wheel is preferred over a larger 4-1/2" or 5" abrasive.

• 11,500 RPM free speed supports efficient abrasive action while keeping the tool matched to common 4" depressed-center grinding wheel applications.
• Heavy duty right-angle head helps reach weld seams, edges, corners, and fabricated parts where straight tools are less convenient.
• Rugged and durable aluminum housing helps balance strength and manageable tool weight for repeated shop use.
• Rear exhaust routes spent air away from the wheel path and work surface to help reduce forward-blown debris.
• 3/8"-24 external spindle thread supports the D3T4 configuration for 4" Type 27 depressed-center grinding wheels.
• Standard equipment includes wheel guard and flange wrench for proper wheel setup and service access.

Applications:

• Fabrication and welding shops — grinding weld beads, smoothing edges, and preparing steel parts before coating, fit-up, or final finishing.
• Industrial maintenance and MRO — dressing repaired components, cleaning brackets, and handling everyday grinding work around plant equipment.
• Automotive, fleet, and equipment repair — shaping repair tabs, cleaning frame sections, and removing small surface defects where a compact 4" wheel is useful.
• Machine and job shops — deburring machined parts, cleaning fixture edges, and preparing small fabrications for assembly.
• General metalworking stations — blending, edge cleanup, and localized material removal on steel, aluminum, and fabricated components when paired with the correct abrasive.

FAQs:

• Q: What wheel does the Cleco 236GLR-115A-D3T4 use?
  A: This model is specified for 4" / 100 mm Type 27 depressed-center grinding wheels. Always confirm that the wheel, guard, spindle thread, and maximum wheel RPM are compatible before use.
• Q: What does Type 27 mean?
  A: Type 27 refers to a depressed-center grinding wheel. The recessed center provides clearance for the mounting hardware and allows practical grinding angles on flat surfaces, edges, and welds.
• Q: How is this different from the W3T4 model?
  A: The D3T4 model is configured for 4" Type 27 depressed-center grinding wheels. The W3T4 model is configured for 4" Type 1 cut-off wheels, which are flat wheels used primarily for cutting rather than face grinding.
• Q: Is this grinder suited for carbide burrs or mounted points?
  A: No. This is a right angle wheel grinder with a 3/8"-24 external spindle thread. For carbide burrs, mounted points, or cartridge rolls, choose a collet-style die grinder instead.
• Q: Why does the air supply matter on this model?
  A: Pneumatic grinders need both pressure and air volume to maintain speed under load. Using the specified 1/2" minimum hose I.D. and a properly sized FRL helps prevent speed drop during continuous grinding.
