We are thrilled to offer the The Makita 7104L Chain Mortiser. This is the first chain mortiser we purchased for our shop and the original, with excellent maintenance, is still in use. It is engineered with power and accuracy features and is ideal for timber framing and log home building. The 10.5 AMP motor delivers 3,200 RPM to quickly notch or cut holes in thick wood stock, and will cut lap joints up to 5-1/8" in. The razor sharp chain is engineered for clean and accurate cutting, with a large adjustable vise and knob for increased versatility. It weighs only 38.1 lbs. for increased portability.
