4. Hitachi GP10DL – Best for Grinding

Hitachi GP10DL

FEATURES

  • 12V Power, 1.5 Amp-hours (Ah) Lithium-Ion battery

  • Anti-vibration system
  • Accommodates all Dremel rotary accessories & attachments
  • Lifetime tool warranty and two-year Lithium Ion battery warranty

The Hitachi GP10DL is primarily a grinder. While it can be used for sanding, wire brushing or polishing or cutting, these activities are not recommended to be performed with this power tool. At 1.1 pounds if it is light with convenient dimensions of 8.2 x 2.2 x 3.7 inches meaning it has excellent maneuverability. It is a powerful tool with the highest speed range on our list. The speed dial also allows the user to set the speed they are most comfortable at. With a soft grip and anti-vibration system, it is also easy to use. However, for rough or long tasks, this tool does tend to heat, with the side location of the air vents meaning it cannot be comfortably used until it has cooled. Also, the tool tends to struggle at the highest RPMs for tougher tasks. This is to be expected given the high power, high-speed range and low dimensions and light build especially for long tasks. At the same time, it is ideal for precision low speed grinding tasks such as grinding nails. The LED work light enhances visibility and reduces the reliance on lighting. It is one of the pricier tools, but Hitachi’s lifetime tool warranty makes it a bargain.

PROS

  • Compact and Powerful
  • Tooltip LED work light
  • Speed adjustment dial
  • Lifetime warranty

CONS

  • Limited Versatility (mainly for grinding)
  • Difficult to maneuver for microwork
  • Does not accommodate the Dremel keyless chuck

It can be used to carry out home improvement or for hobbies/crafts and most lightweight work involving cordless rotary tools. It has a built-in, quick-charging battery, but you cannot purchase the battery individually. It is ideally suited for low-speed precision tasks such as grinding nails or carving pumpkins and not a choice for heavy-duty or industrial work. Though Avid power has a decently high-speed range of 32000RPM, it is not a powerful tool. Using it at full power for the long interval is difficult and will cause the tool to heat.
