The Jet JBOS-5 708404 Benchtop Oscillating Spindle Sander is designed for high efficiency sanding of curved and contoured pieces of stock. The spindle moves with a 1" oscillating motion, helping to reduce heat and protect the stock from burning.

Like every Jet product, the JBOS-5 is designed with advanced features to make your work safer and easier. The table tilts up to 45 degrees to allow you to sand on a bevel, and the built-in dust port allows you to keep your work area, and the air, cleaner and safer. The powerful 1/2 HP motor is designed to last and the removable on/off switch offers added safety by preventing accidental start-ups.

Oscillating sander
By Joe from Mass on March 18, 2015
Very nice machine but wish it came witha fence or pivot pole.
plenty of power, very nice table.
Does not have variable speed nor does it come with a fence.

I would recommend this item to a friend.

Great sander, This is my second JET sander purchase ( already have the belt / disc bench top sander )
The unit was slightly damaged during shipping, however nothing that 10 mns. worth of time to straighten the front right corner and some touch up paint didn't solve. Not worth the time or effort to send back. Although I'm certain that Tools-plus would have immediately resolved any issue.

Strong solid machine. Great table size,
Dust evacuation could be better ! Why would JET use a 2 O.D. fitting ? Had to hunt and retrofit a Rockler 2 1/4' OD to 4 OD and ream the 2 1/4 ID to fit..... after calling JET technical. POOR DESIGN
Wish the inserts were height adjustable. Once again had to retrofit in order to make flush with table top. Simple set screws would have done the trick....Come on JET !

I would recommend this item to a friend.

handy dandy man
By dave from WV on March 23, 2012
super!!!!! well build and tight---a little to much weight to move so a cart in the near future to move it around the shop

I would recommend this item to a friend.

Great machine!
By Nick from Milwaukee, WI on February 6, 2012
I have owned this machine for about 6 months now and I am very happy with it. It is extremely solid on my table while in use and does not seem to 'slide' around much, even with a large amount of pressure against the spindle. The motor is extremely quiet and strong. Again, even with a large amount of force against the spindle, it doesn't seem to bog down at all. Overall, I am extremely happy with the machine and would highly recommend it to anyone!
solid, heavy, strong motor, solid table surface

I would recommend this item to a friend.
