The production cost for battery angle grinder relies on both the price of materials and the production technology. For one thing, the material cost is the most original factor. Whether the figure could decrease not or depends on the technology and the quantitative production. The higher the technology is, the less the cost. This is also the “for another thing”. So is the quantitative production. If the order is larger, the size of quantitative production is greater. Under this, the unit cost would decline. Hoprio group has years of experience in patent design, innovative ideas, exceptional quality, and competitive price of grinder power tool. Hoprio's angle grinder motor series contains multiple sub-products. Hoprio brushless dc motor controller is a result of our forte of exquisite attention to detail.
