Cleco MP4424 Right Angle Die Grinder | MP Series | 0.3 HP | 20000 RPM | 1/4" Collet | Rear Exhaust

Built for deburring, blending, and small-area material removal, the Cleco MP4424 right-angle die grinder combines a compact right-angle format with 0.3 HP output and 20,000 RPM free speed for controlled work with carbide burrs and mounted wheels. The 1/4" collet accepts common die grinder accessories, while the rear exhaust directs air away from the work area to help reduce chip and dust disturbance around the operator.

The MP Series configuration is useful for maintenance teams, metal fabricators, automotive technicians, and general shop users who need a compact pneumatic grinder for edge cleanup, weld dressing, casting work, and light finishing. Its 1.32 lb. weight and 6.4" length help keep the tool maneuverable when working around brackets, housings, fixtures, and other tight-access parts.

• Rear exhaust helps route air away from the operator and the immediate work surface.
• Composite housing keeps the tool weight to 1.32 lb. for improved handling during repetitive grinding or finishing jobs.
• Compact 6.4" length helps the grinder fit into tighter work areas around fixtures, brackets, castings, and assemblies.
• 360° air inlet swivel allows the hose to move with the tool, reducing hose drag as the operator changes angle or position.
• Optional collets are available for 3/16", 1/4", and 6 mm accessory shanks when the application requires alternate tooling.

Applications:

• Metal fabrication and welding shops — cleaning weld edges, blending small areas, removing burrs, and refining contours after cutting or machining.
• Industrial maintenance and MRO — touching up brackets, housings, guards, machine frames, and replacement parts during repair work.
• Automotive and fleet service — gasket surface cleanup, light porting work, rust removal in confined spaces, and general garage grinding tasks.
• Manufacturing and assembly areas — deburring machined parts, trimming sharp edges, and preparing components before coating or final assembly.
• Toolroom and fixture work — shaping, smoothing, and dressing small features where a straight die grinder is harder to position.

FAQs:

• Q: What accessories can be used with the Cleco MP4424?
  A: The catalog lists a 1/4" collet and abrasive capacity for a 1/2" carbide burr or 1" mounted wheel. Always confirm the accessory shank size, abrasive type, and maximum RPM before use.
• Q: What does rear exhaust mean on this die grinder?
  A: Rear exhaust means the spent air exits toward the back of the tool instead of near the work head. This can help keep chips, dust, and grinding debris from being blown directly across the work surface.
• Q: Can this grinder be used with a standard shop air system?
  A: Yes, when the air system can supply clean, regulated air at the manufacturer-rated 90 PSI and is connected with a 1/4" I.D. hose. A properly sized FRL is recommended for consistent performance and tool protection.
• Q: Is the MP4424 better for burrs or mounted wheels?
  A: It can be used with both, within the listed capacity of a 1/2" carbide burr or 1" mounted wheel. Carbide burrs are commonly used for shaping and deburring metal, while mounted wheels are used for smaller grinding and finishing work.
• Q: Why choose a right angle die grinder instead of a straight die grinder?
  A: A right angle grinder helps position the accessory against flat surfaces, inside corners, and confined work areas where a straight tool body may interfere with the part or fixture.
