Makita Chain Mortiser Review

Used for thousands of years by woodworkers around the world, the mortise and tenon joint is both simple and strong, and a critical link in building a timber frame. You could do it the old fashioned way with a drill and chisel or a boring machine, but it would be more time consuming. However, an innovative tool like the Makita Chain Mortiser is a great time saver that provides professional results for both timber framing and log home construction. It can cut a mortise or spline trench quickly and accurately.

Features & Usage:

This mortiser can pivot to three cutting positions without resetting the base . It comes complete with 18mm (23/32") chain, sharpening holder assembly, wrench and chain oil. You can firmly attach onto timbers between 3-1/8” to 12-1/8” thickness with its large adjustable vise. You can also adjust the sliding rear clamp to any desired width with a quick twist of the tension knob. For depth, you can plunge up to 6-1/8” and you can use the depth gauge to set the depth or your mortise. To make sure you’re hitting your mark, the yellow indicator plate and indication plate are factory adjusted for the standard equipped 18mm cutter chain but you will want to fine tune this as you go.

  • Fast chain speed (1,000 feet per minute)

    I love mine. Wouldn’t trade it for anything! You’ll want to figure the price of a new chain into every few jobs at $700 a pop, but the time savings are well worth it.
    Go get one!

    I’m a novice when it comes to framing, so I picked one of these up a few weeks ago, it works great, cuts like a hot knife through butter and very accurate. I’m about to start milling timbers for my new workshop ” 20×20 timber frame, plans from Timber Frame HQ, thanks Brice for your help.” Btw chains go for adout $250 if you shop around.
