The WoodRiver® Mortiser is designed to be used on most stationary drill presses with quill diameters of 75mm (3"), 66.5mm (2.625"), 60mm (2.36"), 55mm (2.17"), 50.8mm (2"), 47mm (roughly 1.875")...
Good value but has it's limits
I bought this kit to help me finish a very speicalized project that I couldn't do on my bench mortisor. The kit seems well made...has lots of adapter a heavy cast iron fence and hold down unit...and 4 chisel bits...on paper this is a amazing value. BUT... The chisel bits simply aren't very high quality...and it hurts the performance of this product. (Really...it would be better if they just didn't add them to the set) That said just one high quality Mortis/bit set would cost more then this entire kit! Luckily I was able to use my Powermactic bits from my bench mortisor so I've been able to get good cut to finish out my project. Something else I'd like to see: Higher fence! The whole reason I bought this kit for my drill press...was to be able to mortise peices larger then 5" high....but the fence can only handle pieces 5" and less. Anyway...a good value...but it's not really a replacement for a real mortisor
