The orbit of the LHR 15ES is 15mm or 3/5”. It is shorter than the orbit of the LHR 21ES and is perfect for working in contoured areas and narrow surfaces, making it a favorite of detailers everywhere. The LHR 15ES has less cutting capacity than its “Big Brother” but does offer a higher rpm level. The medium sized pad (150mm or 6”), perfect balance and amazing lack of vibration make the LHR 15ES a “must-have” for every detailer.
