Product Information

Full details

This Draper D20 Grinder 4.0 Kit is designed for DIY enthusiasts and tradespeople needing a versatile and powerful cordless angle grinder. Its key benefit lies in the brushless motor for efficient power and longer life, along with the included 4.0AH battery and fast charger for immediate use. A minor caveat is the 115mm disc size, which may limit very large material removal tasks.

FAQs

What is the maximum disc size for this grinder?

This grinder is designed for 115mm (4.5 inch) discs.

Can I use batteries from other Draper tool series?

No, this grinder is part of the D20 series and requires D20 batteries for operation. It is not compatible with other Draper battery ranges.

How long does the 4.0AH battery typically last?

Runtime varies significantly based on the application (e.g., cutting vs. grinding) and material. The 4.0AH battery provides substantial runtime for most common tasks.

What is included in the kit?

The kit includes the D20 Brushless 115mm Grinder (bare tool), one D20 4.0AH battery, one D20 4A fast battery charger, and a heavy-duty medium 28L tool bag.

How do I change the grinding disc?

First, ensure the battery is removed. Then, press and hold the spindle lock button, and use the appropriate spanner to unscrew the outer flange nut.

Is this grinder suitable for heavy-duty construction work?

While robust, it is best suited for general DIY, workshop use, and moderate site tasks. For continuous, extremely heavy-duty industrial applications, a larger or corded grinder might be more appropriate.

Troubleshooting

Grinder not powering on

Ensure the battery is fully charged and properly seated in the grinder. Check that the safety switch is engaged correctly.

Reduced power or performance

The battery may be low; recharge it. Check if the air vents are blocked and clean them. Ensure the disc is not damaged or excessively worn.

Disc not tightening properly

Verify you are using the correct spanner for the disc and nut. Ensure the M14 thread is clean and undamaged. Make sure the spindle lock is engaged firmly while tightening.

Overheating during use

Reduce the load on the tool and allow it to cool down. Ensure air vents are clear. Avoid continuous heavy use beyond the tool's intended capacity without breaks.

Pros and Cons

Pros

  • Powerful brushless motor for efficient performance.
  • Includes battery, charger, and tool bag for a complete kit.
  • Good battery capacity (4.0AH) for extended use.
  • Durable construction suitable for demanding tasks.
  • Versatile with 3-position side handle and standard M14 thread.

Cons

  • 115mm disc size limits very large material removal.
  • As a cordless tool, runtime is dependent on battery charge.
  • Can be heavier than corded alternatives for prolonged overhead work.

Setup, Compatibility & Care

Setup:

  1. Ensure the D20 4.0AH battery is fully charged using the included D20 4A fast charger.
  2. Attach the desired disc (cutting, grinding, flap) to the grinder, ensuring it is compatible with the M14 thread and the correct disc type for the task.
  3. Secure the disc using the spindle lock mechanism and appropriate spanner (usually supplied with discs or grinder).
  4. Attach the 3-position side handle for your preferred grip and control.
  5. Insert the charged battery into the grinder base until it clicks securely.

Compatibility:

  • This grinder is part of the Draper D20 series, meaning it is compatible with all Draper D20 lithium-ion batteries and chargers.
  • Uses standard M14 threaded accessories (discs, wire brushes).

Care:

  • Always disconnect the battery before changing discs or performing maintenance.
  • Keep the air vents clean and free from dust and debris to prevent overheating.
  • Store the grinder, battery, and charger in a dry, protected environment, preferably in the supplied tool bag.
  • Wipe down the exterior with a slightly damp cloth as needed; avoid solvents.
