A wobbly 6-inch grinder with a flexing tool rest is the difference between a sharp drill bit and a ruined one. Trade bench grinders use induction motors with smooth ramps, rigid cast-iron bases, and adjustable tool rests that don’t deflect under hand pressure. In workshops across the UK, engineers and workshop owners rely on these machines for precision work. Models like the Grizzly G8456 or the Delta 23-190 typically range from £200 to £500, offering robust performance and durability. For those with tighter budgets, units such as the Jet JBG-6 come in at around £150 but still provide reliable service. The right bench grinder ensures that your tools stay sharp and true, making a significant impact on daily operations without breaking the bank.
How we picked these
- Motor: induction motors (not universal) run cooler, quieter, and last decades. Universal motors are DIY-tier.
- Wheel size: 6" (150mm) is workshop standard; 8" (200mm) for tool-room and larger work.
- Speed: 2,850 RPM (50Hz UK) is correct for vitrified wheels. 3,000+ RPM exceeds safe wheel surface speed.
- Wheel quality: most grinders ship with junk wheels - budget £30-£60 for trade-grade replacement wheels (Norton, 3M, Tyrolit).
- Tool rest: must be adjustable and rigid. Stamped sheet-metal rests flex and cause wheel chatter.

It features an 8-inch induction motor with two-speed settings - 1,400 and 2,850 RPM - which offers versatility in grinding tasks. However, the default wheels are basic and should be replaced for better performance.

JET IBG-8 (200mm Industrial)
Price: £450-£600 | Best for: professional workshop / tool-room
The JET IBG-8 is a stalwart bench grinder for professional workshops, tipping the scales at 26kg to keep vibrations in check during production sharpening. Sporting a hefty 750W motor and 32mm wheels on a robust cast iron base, it's priced from £450 to £600. While its industrial pedigree is hard to beat, single-speed operation limits flexibility, and the premium price might give some pause.

Pros
- Heavy 26kg base eliminates vibration
- 32mm wide wheels for production sharpening
- JET industrial pedigree
Cons
- Single-speed only
- Premium price for the spec

Metabo DS 200 (200mm)
Price: £300-£420 | Best for: German build at trade workshop level
The Metabo DS 200 (200mm) is a solid choice for UK trade workshops, built with German engineering and featuring a robust cast iron tool rest. Priced between £300 and £420, it offers a quiet induction motor but comes at a premium compared to similar models from Draper or Sealey. Its 2,980 RPM speed is right up against the safe limit for its wheel size.

| Speed | 2,980 RPM |
|---|
| Tool rest | Cast iron |

Pros
- Metabo German engineering
- Rigid cast iron tool rest
- Quiet induction motor
Cons
- 2,980 RPM is at the wheel safe-speed limit
- Premium price vs Draper / Sealey

Record Power RPBG6 (150mm 6-inch)
Price: £140-£190 | Best for: smaller workshop / tool-rest sharpening
The Record Power RPBG6 is a solid bench grinder for UK workshops, priced between £140 and £190. Boasting a 150mm wheel and adjustable cast iron tool rest, it excels in precision sharpening tasks on smaller benches. However, its 370W motor limits it to light-duty work, and the 150mm wheel size restricts handling larger pieces.
| Wheel | 150mm x 20mm |
|---|
| Motor | Induction, 370W |
|---|
| Speed | 2,850 RPM |

Pros
- Record Power UK brand
- Cast iron tool rest at sub-£190
- Compact 6" for small benches
Cons
- 150mm wheel limits larger work
- 370W motor for light duty only

Frequently asked questions
6-inch or 8-inch bench grinder?
6-inch is fine for general sharpening (drill bits, chisels) and light material removal. 8-inch is better for larger work and tool-room use because larger wheels stay flatter longer, generate less heat per pass, and have more material to dress before retirement. Workshop default: 8-inch.
Why do trade grinders cost 5x DIY models?
Three reasons: (1) induction motor vs universal - induction lasts decades and stays cool; (2) cast iron rigid base + rest vs stamped sheet metal - no flex under hand pressure; (3) properly balanced spindles vs cheap pressed shafts - far less vibration. The DIY-tier grinder vibration is what ruins drill-bit sharpening.
Should I replace the wheels that come with the grinder?
Yes - almost universally. The wheels supplied with grinders below £400 are generic 60-grit aluminium-oxide. For HSS sharpening, use a white aluminium-oxide 100-grit. For tool-steel work, use a green silicon-carbide. Norton, 3M, Tyrolit make trade-grade wheels for £25-£60 each.
Variable speed or single-speed?
Single speed (2,850 RPM) is fine for general grinding. Variable speed is genuinely useful if you sharpen HSS drill bits and cutting tools - slowing to 1,500 RPM reduces heat and prevents tempering loss. For workshop use, single-speed is simpler and more reliable; for tool-room work, variable speed is worth the cost.
Is JET worth £450+ vs Sealey at £250?
If you sharpen drill bits and chisels a few times a month - Sealey is fine. If you grind production parts or sharpen multiple tools daily - JET's 26kg base and 32mm wide wheels are noticeably better. Most workshops won't push the Sealey hard enough to feel the JET difference.
