4" (100mm) angle grinders are the most common grinder size in the Philippines. They are light and easy to control, and they handle cutting steel bars, grinding welds, cleaning rust and cutting tile and concrete. This collection includes corded grinders from about 570W to 1200W, cordless models and a pneumatic grinder.
How to choose a 4" angle grinder
- Power: 600W to 750W models like the Makita 9520B and Bosch GWS 060 suit home use and occasional jobs. 850W and above, such as the Makita 9556HN, DeWalt DWE8300S and DCA ASM10-100H, keep their speed under load for daily fabrication.
- Switch: slide switches can stay on for long runs. Paddle switches like the one on the DeWalt DWE8200PL stop the grinder when you let go.
- Variable speed: models like the Bosch GWS 900-100 S and Mailtank SH02 let you slow down for polishing, wire brushing and stainless steel.
- Corded or cordless: 18V and 20V cordless grinders from Makita, Bosch and DeWalt work where there is no outlet. Buy the bare tool if you already have batteries.
