The flexibility to perform compound-angled mortises with perfect control is what sets this Heavy-Duty Mortiser apart from all others. Simple adjustments allow the head to tilt up to 30° left or right, and the fence also pivots up to 30°, providing just about any combination of angles. Handwheel controls allow you to move the table left/right and forward/backward with precision and ease. Adjustable work stops help ensure consistent results with production runs. Round all this out with a 1-1/2 HP motor and solid cast iron construction, and you'll see why this has become the mortiser of choice for busy shops around the country!

Design needs improving. The bolts that hold vice down can hit the stop knobs. Stop knobs small in diam and not enough torque and my mortise lengths were creeping. Other models have longer toggles. The vice shaft is inches short of fence requiring blocks and shims. The vice difficult to turn. No instructions but pin holding foot on was too tight causing friction. Service was great as the sent new shaft quickly but that was not the problem. The base unit was dented and separated where horizontal top meets side and plastic handle that changes the handle position was broken. Those two shipping defects are cosmetic for the most part.

Another Fine Grizzly Tool 05/04/2019 2:18:59 PM

This is the second major Grizzly tool I have bought and I am very happy with both. The first was an 8" spiral head jointer G0858. Both machines came very well crated from the factory, neither required any fine adjustments before use. I have used the jointer a lot now and am very pleased with the results from it. This mortiser is my first one and while I've made several practice joints with it, I've yet to complete a big project, so can only say the results with this machine meet my expectations completely. With this machine, I also bought a set of Premium Mortising Chisels from Japan, T10018 and similar numbers. I have only used the 3/8" set so far, but it has worked very well in walnut and elm and came from the factory well sharpened.

Two points to make: First, while Grizzly shipping is great with UPS Freight and parcel service, showing up on time and in fine shape, back-orders can take time. The chisels and original mortiser I ordered took an extra 3 months to show up. Since I was in no hurry, that worked out as this mortiser was in stock and went on sale, letting me change my order to a better machine for only a bit more money. The chisels were worth the wait.

Second, a suggestion for assembling big, top-heavy machines. While the manual calls for having a few guys to lift the 300# machine on top of the base cabinet, I am a one-man shop in the country and wanted to avoid imposing on a few friends to make a long drive. First, I considered assembling it outside, using my tractor to lift it before using a hand truck to move it inside. That was still going to be very awkward and unstable. In the end, I remembered that I had an engine hoist in the barn from pulling a pickup truck engine and using a short chain, used that hoist to lift the machine and position it on the cabinet. The hoist could be assembled in the shop avoiding door issues and safely did the job. Even if you don't own one, I'd say renting one for a half day beats trying to man-handle a heavy, awkward piece of equipment with a couple buddies.

The repeatability and reduced set up time compared to mortise attachments for drill presses, means getting to the task at hand very quickly. Powerful 1.5 hp. motor makes this unit a boss.

The Grizzly G0448 is my third hollow chisel mortiser. I was hesitant to invest so much money in a mortiser since I am only a hobbyist. However, I was doing a project that would require a lot of mortises and I had enough frustrations with the previous cheap ones and so ordered the G0448. It is worth every cent. The ease of use, speed in moving the work piece left/right and fore/aft is such a treat. The depth stop setting is very easy to adjust and will not move under pressure, like some other mortisers. Every time I use it I realize I made the right decision with this tool purchase.
