What a mini angle grinder is in this guide

Here, a mini angle grinder is a cordless cut-off tool for a disc of about 75 mm or 76 mm. It is for a seized bolt or a thin bracket in a gap, not a rotary multi-tool and not a 115 mm grinder. Hire desks use the same nickname for the other machine. Rapid Hire lists a "Mini Grinder 115mm" for pipe, rust, weld beads and mortar.

Disc diameter, bore and stated speed

Treat 75 mm, 76 mm and 3 inch as one class when the listing states a diameter. A blank diameter means you cannot order a spare from the page. The usual disc here has a 10 mm bore. Rivlox states M5 and INGCO prints M6. A 115 mm disc is a 22.23 mm bore on M14 and will not mount. Worx's WX801 page states 9.5 mm, so those discs do not swap just because both tools are called 76 mm. Most listings state 19,500 rpm. ConBlom states 28,000 rpm. Weytoll B0CY4Z2PM8 states 7,000 rpm. The disc's own maximum must be at least the speed on the tool. BS EN IEC 62841-2-3 caps accessories at 80 m/s. That limit is not a test of these kits.

Batteries and what the listing really includes

Read the included-components line before the title. Most kits are closed packs you cannot share with a drill you own. INGCO is one 2.0 Ah P20S battery and a charger at £55.99. Normodic is a bare body at £25.99 that names Makita packs and includes no battery or charger. That fit is a listing claim, not a Makita certificate. Rivlox includes two 1,500 mAh packs. TEENO and ConBlom name two 2,000 mAh packs and a charger. A 21 V claim a review denies is not a platform.

Guard, motor words and review pattern

A bullet that says baffle is a claim, not proof a guard sits between you and the sparks. The guard stays on. A tight gap is why the tool is small, not a reason to remove it and fit a larger disc. Eborrkee's listing describes a wood disc with hundreds of teeth. GOV.UK product safety alert PSA2 warns that toothed saw blades on angle grinders kick back, so that bullet is a reason to walk away. JinsenTGG is 3.4 from 288 reviews, with cut-outs every few seconds. INGCO is 4.7 from 75 and stays on small jobs, with stalling when the cut is heavy.

A short checklist

Work down the listing, then open the comparison. Diameter and bore are both printed, and they are not a blank field plus a 22.23 mm disc you already own. The disc's maximum rpm is at least the tool's stated speed, including 28,000 rpm on ConBlom and 7,000 rpm on Weytoll B0CY4Z2PM8. Battery count, charger and platform are on the included-components line. A guard or baffle is mentioned, and the box does not depend on a toothed wood blade. If those checks fail, the lower price is not a saving.

Common questions

What bore and spindle should the disc match?

Match the hole, then the thread. The usual disc here is a 10 mm bore. Rivlox states M5. INGCO's title states M6. A 115 mm disc is 22.23 mm on M14 and will not fit. Worx's WX801 page states 9.5 mm, so a 10 mm disc is not automatic there either. If the Amazon attributes omit the bore, do not guess it from the diameter.

Why do some listings say 16.8 V and others 12 V or 21 V?

Those are title claims on closed packs, and two are already contradicted. Weytoll B0FFBN39ZN says 21 V only in the title, the attributes state no voltage, and a review says it is not 21 V. JinsenTGG's title says 12 V, and a review says the packs are marked 16.8 V and 18 V. INGCO states 20 V on P20S. Read the label on the pack you receive.

Does a higher rpm number mean a better tool?

No. Most listings state 19,500 rpm. ConBlom states 28,000 rpm, and one Weytoll states 7,000 rpm. A higher number only raises the speed the disc must be marked for. The 80 m/s cap in BS EN IEC 62841-2-3 is a standard limit, not a test of these kits. One reviewer of the 7,000 rpm Weytoll preferred that lower stated speed for light panel work.

Should I buy two small batteries or a body for packs I own?

Buy two own-brand packs only if a charger is in the box and reviews do not describe dead batteries. TEENO and ConBlom state two 2,000 mAh packs. INGCO includes one 2.0 Ah P20S battery. Normodic includes no battery and claims Makita packs. A bare body is the better route only when you already own that platform. Two or three reviews are not a durability test.

What does brushless on the title actually guarantee?

Nothing, until the rest of the listing agrees. JinsenTGG's title says brushless and a bullet says brush motor, and UK reviews say it is not. Normodic's title says brushless, and a review that looked inside describes brushes. For a brushless tool, use a maker page for a named model, such as Bosch's GWS 12V-76, rather than a title this capture has already contradicted.
