Cleco 216GLSB-250-C4 Inline Grinder | 216 Series | 0.7 HP | 25,000 RPM | 1/4" Collet | Aluminum Housing | Side Exhaust

Built for metal deburring, weld cleanup, edge breaking, and carbide burr work, the Cleco 216GLSB-250-C4 inline grinder delivers compact pneumatic grinding performance in a straight-body configuration that gives operators direct control over the cutting point. Its 0.7 HP motor provides useful removal power for production and maintenance work, while the 25,000 RPM free speed supports fast stock removal when paired with properly rated carbide burrs. The 1/4" collet accepts common industrial burr shanks, and the 3/4" carbide burr abrasive capacity makes this model a practical choice for fabrication shops, foundries, transportation equipment work, and MRO departments that need a small grinder with high spindle speed.

Part of Cleco’s 216 Series, the 216GLSB-250-C4 uses an aluminum housing to keep tool weight manageable during detail grinding and includes side exhaust, which vents air away from the front of the tool to help reduce chip disturbance at the work surface. The lock-off lever helps reduce unintended throttle activation during handling, while the inline body shape supports controlled burr positioning in channels, bores, weld transitions, and tight fabrication areas.

Features:

• Inline grinder configuration gives the operator direct control when guiding carbide burrs into edges, holes, welds, and recessed areas.
• 0.7 HP pneumatic motor supplies strong material removal capability for a compact die grinder body.
• 25,000 RPM free speed supports efficient deburring and shaping when used with correctly rated carbide burrs.
• 1/4" collet accepts common industrial carbide burr shanks used in fabrication, repair, and finishing work.
• 3/4" carbide burr abrasive capacity supports heavier burr work than smaller precision pencil grinders.
• Aluminum housing helps reduce overall tool weight while maintaining a durable body for shop use.
• Side exhaust directs air away from the front of the grinder, helping keep chips and grinding debris from blowing directly across the work point.
• Lock-off lever helps prevent accidental throttle activation during repositioning, storage, or tool handling.

Applications:

• Metal fabrication shops — deburring cut edges, cleaning weld toes, blending small transitions, and shaping tight metal details with carbide burrs.
• Foundry and casting cleanup — removing flash, parting lines, and small casting imperfections where a high-speed burr grinder is easier to control than a wheel grinder.
• Transportation equipment manufacturing — cleaning brackets, frames, weldments, and repair areas on truck, rail, trailer, and equipment components.
• Industrial maintenance and MRO — opening holes, removing burrs, touching up damaged edges, and preparing small surfaces during plant repair work.
• Welding and repair departments — reaching into corners, channels, and tube work where a straight inline grinder offers better access than a larger angle grinder.

FAQs:

• Q: What accessories fit the Cleco 216GLSB-250-C4?
  A: This grinder uses a 1/4" collet and is intended for compatible 1/4" shank carbide burrs up to the listed 3/4" abrasive capacity. Always confirm the burr’s maximum RPM rating before installation.
• Q: What does side exhaust mean on this inline grinder?
  A: Side exhaust means the tool vents air from the side of the housing rather than straight out the front or rear. This can help reduce airflow directly at the grinding point and may be preferred when chips or dust control near the work surface matters.
• Q: Can this grinder be used with mounted stones or small grinding wheels?
  A: Use only accessories that match the tool’s collet size, intended accessory type, and 25,000 RPM maximum speed requirement. Do not use saw blades or non-reinforced grinding wheels on this tool.
• Q: Is this the right grinder for precision engraving work?
  A: This is a 0.7 HP inline die grinder for burr work and material removal. For very fine engraving, polishing, or delicate deburring, a smaller pencil grinder with a 1/8" collet and higher free speed may be more appropriate.
• Q: What air setup should be used with this pneumatic grinder?
  A: Use clean, regulated air at the manufacturer’s specified 90 PSI and connect the tool through a properly sized hose and FRL. The listed minimum hose size is 1/4".
