Summary
A compact 18V cordless angle grinder for the Metabo HPT MultiVolt battery platform, with a brushless motor and safety features like anti-kickback and a lock-off paddle switch. Check whether you already own Metabo HPT batteries before buying: the bare-tool price does not include them.
Strengths
- Lightweight at 5.1 lbs bare, with a 2.2" grip for tight spaces.
- Brushless motor eliminates carbon brush maintenance.
- Anti-kickback, quick brake, soft start and zero-voltage restart protection are all standard.
- Works with any Metabo HPT 18V or MultiVolt battery from 1.5Ah to 8.0Ah.
- User-serviceable dust filter protects the motor.
- Three side handle positions for different cutting angles.
Weaknesses
- No independent instrumented test of this exact model was found.
- No exact-model owner discussions exist on Reddit or forums.
- The 750 W output is a manufacturer rating, not independently measured.
- Bare-tool only: battery and charger are extra, which pushes total cost above the sticker price.
- 8,000 RPM is lower than some competitors (RIDGID R86047B runs 9,000 RPM).
- 1-year tool warranty is shorter than some competitors offer.

Full research notes and sources
What it is and who it is for
The G1812DFQ4 is a 4-1/2" cordless angle grinder built for light to medium grinding and cutting. It runs on Metabo HPT’s 18V and MultiVolt 36V battery platform, so it makes the most sense for users who already own those batteries. The bare-tool format means you are buying the grinder body only — batteries and charger are sold separately.
Safety and handling
Metabo HPT equips this grinder with a lock-off paddle switch, an electric brake, anti-kickback shutoff, zero-voltage restart protection and soft start. The 2.2-inch grip diameter and 5.1-lb weight position it as a one-handed tool for confined work. A three-position side handle gives options for left- or right-handed use.
Battery platform and running costs
The tool accepts any 18V battery from 1.5Ah to 4.0Ah, plus MultiVolt 5.0Ah and 8.0Ah packs. Burns Tools lists the G1812DFQ4M bare tool at $169.00. Batteries and chargers are sold separately, so the real startup cost for a new user is the grinder plus a battery and charger. MultiVolt 8.0Ah is the maximum runtime option.
What owners say
No exact-model owner discussions were found on Reddit or forums. General Metabo HPT brand sentiment on Reddit praises value for money, battery platform compatibility and warranty support. Some users report positive warranty experiences, including replacements past warranty and no-questions-asked battery replacements. This is brand-level sentiment, not exact-model evidence.
Is it worth it?
At $169 bare tool from Burns Tools, the G1812DFQ4 is a reasonable addition if you already own Metabo HPT 18V or MultiVolt batteries. For buyers without existing batteries, the total cost of grinder plus battery and charger approaches kit-price offerings from DeWalt, Milwaukee and Makita. The lack of independent testing means you are relying on manufacturer claims for power and durability. The 1-year warranty is shorter than some competitors — RIDGID offers a lifetime service agreement on its R86047B grinder.
