Overview
The AOBEN AT102D-115 is a cordless grinder running on a 21 volt battery platform, spinning up to 9500 RPM. At 4.82 kilograms it is heavier than the smallest cordless angle grinders on the market.
A 21 volt platform and 9500 RPM top speed put this grinder in line with cordless angle grinders built for cutting, grinding and surface work without a cord tethering the user. At 4.82 kilograms, roughly 10.6 pounds, it runs heavier than compact single-battery grinders, which may reflect a larger battery, added shielding or a heavier motor housing not broken out in the spec sheet. The listing shows strong recent purchase volume.

Who it's for
Suited to users who want cordless freedom for grinding and cutting jobs and do not mind extra weight for potentially more running time. Less ideal for overhead or one-handed work where a lighter grinder is easier to control.
Strengths and trade-offs

Performance notes
The 9500 RPM top speed on a 21 volt battery platform is in the usual range for cordless angle grinders handling cutting and grinding discs. The 4.82 kilogram weight is on the heavier side for this class, which can help stability on flat work but makes overhead or extended one-handed use more tiring.
