How the points were given
Each grinder is scored on performance, build, value, safety and warranty. Safety here means a stated safety lock or switch; the YON.SOU states a safety lock and the Gunpla states a safety switch, while the other three state no safety feature, so they score zero on safety. None of the five states a warranty term, so every grinder scores zero on warranty.
| Product | Shop Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |

| YON.SOU YDG21061 | 9.6 | 30 | 22 | 21 | 7 | 0 |

| Sunex SX2PK Set | 9.3 | 23 | 19 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Buying guide: best air die grinder under 100
Free speed and air consumption
Free speed is the headline figure on four of the five: 20,000 RPM on the NEIKO, YON.SOU and Gunpla, and 22,000 RPM on the Baisiky, while the Sunex set states no speed at all. Air consumption is stated on only two: 4 CFM on the NEIKO and 3.5 CFM at 90 PSI on the Baisiky. Every grinder here is air-powered and needs an air compressor before use, so check the compressor against the stated consumption figure where the listing gives one. For rust work, see the best air die grinder for rust removal.
Angle, straight or extended reach
Shape decides where the grinder can work. The NEIKO, YON.SOU and Gunpla are right-angle grinders, with the NEIKO adding a pistol grip, and all three suit tight spaces where a straight grinder cannot reach. The Baisiky is a straight grinder at 11 in long with a 6 in extended reach for confined spaces. The Sunex set covers both shapes with a straight and an angled grinder in one box.
| Grinder | Shape | Free speed | Air consumption |
|---|---|---|---|
| YON.SOU YDG21061 | Right angle | 20,000 RPM | Not stated |
| Gunpla Angle Grinder | 90 degree angle | 20,000 RPM | Not stated |
| Baisiky 11in Extended | Straight, extended | 22,000 RPM | 3.5 CFM at 90 PSI |
| NEIKO 30060A | Right angle, pistol grip | 20,000 RPM | 4 CFM |
| Sunex SX2PK Set | Straight and angled set | Not stated | Not stated |
Figures as stated in each listing. The NEIKO figure uses the title and spec table value of 20,000 RPM, not the 25,000 RPM in its bullets.
Collets, accessories and what comes in the box
Collet size is 1/4-inch across the group, with the Baisiky adding a 1/8-inch collet. The Gunpla includes 26 sanding discs across 5 types, the YON.SOU includes wrenches and a quick connector, the Baisiky includes 2 wrenches and the NEIKO includes a hex key for its regulator. The Sunex set includes an assembly guide and no stated abrasives. An air tools setup with the right collet and discs matters more than a bare grinder with nothing to fit it.
Garage Fit Check
- Check the compressor against the stated consumption: 4 CFM on the NEIKO and 3.5 CFM at 90 PSI on the Baisiky; the other three state no consumption figure.
- Check the shape against the job: right-angle heads for tight spaces, the 11 in Baisiky for extended reach, and the Sunex set when both shapes are needed.
- Check the collet: 1/4-inch across the group, with a 1/8-inch collet also stated on the Baisiky.
- Check the safety feature: a safety lock on the YON.SOU and a safety switch on the Gunpla; the other three state none.
Wear eye protection with every air tool, use impact-rated sockets on impact wrenches, disconnect the air line before changing accessories, and finish lug nuts with a torque wrench to the vehicle's spec. See OSHA eye and face protection. Read our Safety Disclaimer.
