Cleco 236GLR-200-C4 Inline Grinder | 236 Series | 0.6 HP | 20,000 RPM | 1/4" Collet | Aluminum Housing | Rear Exhaust

Built for controlled deburring, casting cleanup, and general metal removal, the Cleco 236GLR-200-C4 inline grinder delivers 0.6 HP with a 20,000 RPM free speed for use with properly rated carbide burrs. The 1/4" collet accepts common industrial burr shanks, while the straight inline configuration helps operators guide the tool into bores, slots, edges, and machined features where direct tool control matters.

Part of the 236 Series, this model uses an aluminum housing and rear exhaust configuration to route air away from the work area. Its 1" carbide burr capacity, compact 6.8" length, and 1.4 lb weight make it well-suited for fabrication shops, foundries, maintenance departments, and machine shops that need a straight pneumatic grinder for repeat burr removal and part cleanup.

FAQs:

• Q: What is the Cleco 236GLR-200-C4 used for?
  A: It is an inline pneumatic grinder used with carbide burrs for deburring, casting cleanup, edge finishing, and localized metal removal. The straight body style gives the operator direct in-line control when working on holes, slots, and machined features.
• Q: What does rear exhaust mean on this grinder?
  A: Rear exhaust means spent air exits toward the back of the tool. This helps keep exhaust away from the cutting area, which can be useful when working around loose chips, dust, or small part features.
• Q: Can this grinder use mounted wheels?
  A: The catalog listing for this SKU specifies a 1" carbide burr abrasive capacity. Do not assume mounted wheel compatibility unless the accessory fits the 1/4" collet, is approved for the tool, and is rated for at least 20,000 RPM.
• Q: What air supply setup should be used?
  A: Cleco rates this grinder at 90 PSI / 620 kPa and specifies a minimum hose I.D. of 5/16" / 7.9 mm. For best results, use clean, regulated, lubricated air through a properly sized FRL.
