A bargain angle grinder with no restart protection and a slow brake is how workshops lose fingers and discs. Trade grinders from Makita, Bosch, and Metabo add a mechanical brake, anti-kickback, and restart protection, ensuring they hold speed under load instead of bogging down in a cut. In the UK market for 2026, expect to pay between £150 and £300 for these robust tools, which are designed with features like electronic circuit breakers and soft-start mechanisms that cheaper models lack. These grinders come equipped with variable speed controls and ergonomic handles, making them indispensable in any serious workshop setting where efficiency and safety are paramount.
How we picked these
- Disc size: 115mm for tight work and lower weight, 125mm for more cut depth and the widest disc choice. 125mm is the workshop default.
- Brake: a disc that keeps spinning after release is a hazard. Look for a mechanical or electronic brake (Makita XPT, Bosch).
- Power: 720-900W handles general fabrication; 1400-1550W for heavy stock removal and cutting bar.
- Safety: restart protection (won't restart when plugged in switched-on), anti-kickback, and a tool-free guard are trade essentials.
- Corded vs cordless: corded for sustained bench work; 18V brushless (Makita XGT/LXT, Milwaukee M18 FUEL) for site and no-trailing-lead jobs.

Frequently asked questions
115mm or 125mm angle grinder?
125mm is the workshop default: it cuts deeper and has the widest choice of discs. 115mm is lighter and better in tight spaces. Both take the same arbor (M14), so disc fitment is the same; the 125mm just accepts larger-diameter discs.
Do I need a brake on an angle grinder?
For frequent use, yes. A braked grinder stops the disc in 1-2 seconds instead of 30-60. That dramatically reduces the chance of injury when you set the tool down and the risk of a still-spinning disc snagging. DeWalt, Metabo and Milwaukee fit brakes; most budget grinders don't.
What power do I need for cutting steel bar?
For sustained cutting of thick bar and heavy stock removal, choose 1400-1550W corded (DeWalt DWE4233, Metabo WEV 15-125) or an 18V brushless cordless. A 720-750W grinder will do it but bogs down and runs hot on heavy work.
Is a cordless angle grinder powerful enough for trade use?
A brushless 18V grinder like the Milwaukee M18 FUEL matches a mid-range corded unit for most fabrication and is far more convenient on site. The trade-offs are runtime (carry spare batteries) and higher upfront cost once you add a battery and charger.
What's restart protection?
Restart (or no-volt-release) protection stops the grinder restarting on its own if the power is cut and restored while the switch is still on - for example after a trip or unplugging. It's a standard safety feature on trade grinders and prevents a grinder leaping to life unexpectedly.
