Makita 3901 Plate Joiner offers a 10000 RPM, 5.6 Amp motor, six cutting depths for different biscuit sizes and a precision fence that angles with positive stops at 0, 45 and 90°. Changing biscuit sizes is as quick and easy as turning the adjustment dial. The rack-and-pinion fences action is as smooth as any on the market at the level and our test cuts were clean and dead-on accurate.
