Cleco MP4430 Inline Die Grinder | MP Series | 0.3 HP | 23000 RPM | 1/4" Collet | Rear Exhaust

Built for straight-line access during deburring, blending, and small-area grinding, the Cleco MP4430 inline die grinder delivers 0.3 HP power and 23,000 RPM free speed in a compact MP Series body. The 1/4" collet accepts common carbide burrs and mounted wheels, making this tool useful for edge cleanup, weld touch-up, casting work, and general shop finishing where control matters more than aggressive stock removal.

The inline body helps operators work directly into openings, bores, slots, and narrow part features where a right-angle head may not fit. At 0.88 lb. and 6" long, the MP4430 is easy to position during repetitive maintenance, fabrication, and repair work, while the rear exhaust routes air away from the work area to help reduce debris movement around the accessory.

FAQs:

• Q: What accessories fit the Cleco MP4430?
  A: The MP4430 uses a 1/4" collet and is listed for a 1/2" carbide burr or 1" mounted wheel. Always confirm that the accessory shank fits the collet and that the accessory’s maximum RPM equals or exceeds the tool speed.
• Q: What is an inline die grinder used for?
  A: An inline die grinder is used for straight-access deburring, shaping, and finishing. It is especially useful when the operator needs to reach into holes, slots, inside corners, or long narrow work areas.
• Q: How is the MP4430 different from a right angle die grinder?
  A: The MP4430 has a straight inline body, which is better for direct forward access. A right angle die grinder is better when the accessory needs to approach the work surface from the side or at 90 degrees.
• Q: Can this grinder be used on a shop air system?
  A: Yes, when the air supply is properly regulated and matched to the tool’s requirements. Use clean, dry air and a properly sized hose and FRL to help maintain consistent speed and protect the air motor.
• Q: Is this tool suitable for heavy grinding?
  A: No. The MP4430 is best suited for small burrs, mounted wheels, deburring, and light finishing work. For larger wheels or aggressive stock removal, choose a grinder rated for the correct wheel size and power level.
