Overview
The MYTOL H21K3 is a corded electric sander drawing 7.2 amps on a 120-volt circuit, spinning at 1,800 RPM. At 7.19 kilograms it's a heavier tool, built for sustained work rather than quick handheld touch-ups.
The combination of higher amperage draw and a substantial 7.19 kilogram weight points to a sander built for larger surface areas, floors or extended stripping jobs, rather than a light orbital finishing sander. Being corded removes battery run time as a concern but ties the tool to an outlet and cord management.
- 120 volt AC corded power source
- 7.2 amp draw
- 1,800 RPM operating speed
- 7.19 kilogram item weight
Who it's for
Fits users tackling larger sanding jobs, floors, decks or extended surface prep, where sustained corded power outweighs portability. Less suited to buyers wanting a light handheld sander for quick, small-area touch-ups given the 7.19 kilogram weight.
Strengths and trade-offs
Drawn from this product's published specifications.
- Sustained corded power with no battery to manage
- 7.2 amp draw supports extended sanding sessions
- 7.19 kilograms is heavy for handheld, overhead work
- Corded design ties it to an outlet and cord management
Performance notes
At 1,800 RPM the H21K3 runs slower than many handheld orbital sanders, a pace that suits controlled material removal over speed. The 7.2 amp draw on a 120-volt circuit gives it sustained power for longer sessions, and its 7.19 kilogram weight helps keep the sanding surface pressed flat without extra hand pressure, though that same weight adds fatigue over a full day of overhead or vertical work.
