Here is a very nice example of a late 1970's Rockwell model 4485 Commercial Duty Orbital Finish Sander that appears to have seen very little use. The main housing is made from die cast aluminum alloy with only the top cap made from high impact plastic. Sanding sheet size is 4 1/2" X 11", standard 1/2 sheet size.

Rockwell Industries purchased Porter Cable in 1960 and for the first few years labeled tools with both names. By 1964 the Porter Cable name was dropped and the tools were labeled with only the Rockwell name. When Rockwell sold it's Porter Cable & Delta divisions in 1981, both companies reverted back to their original names again.

This sander is a commercial duty version of the Porter Cable model 505 and features basically the same specs and performance; 10,000 OPM, 2.3 amp motor, 100% ball bearings, smooth, low vibration, swirl free finish sanding. Solid metal frame for precision seating and alignment of bearings, motor, and fan, providing the maximum in long, trouble-free tool life and sands flush & into corners.

This sander is in perfect working order and hums like a kitten when turned on. It features a thick heavy duty felt backing pad that remains in fine condition. The electric cord is in perfect condition. A few minor scrapes to the paint on the lower aluminum housing is the only negative I can find.

When I was a young man, I worked in two different cabinet shops and these Rockwell-Porter Cable 1/2 sheet sized sanders were an industry standard for quickly producing a fine swirl free finish surface on face frames as well as large panels. These sanders always leave a perfectly flat surface and will not dig in and leave divots.

Shipping & Handling

Buyers must provide a current and valid "ship to" address in their and or paypal accounts. They should also be available to receive, pick up or sign for parcels, as might be required by the United States Postal Service.

Buyers will receive an invoice with the shipping cost that is clearly displayed in the shipping calculator near the top of this listing. Please consider shipping cost when placing your offer. All items are shipped via USPS Priority Mail. Exceptions may be made for international buyers (see notes below).

The Shipping Calculator determines the shipping cost based on the estimated weight to the zip code on file in your account. The cost varies to different shipping zones. When we view this item, it shows only the cost to our zip code.

We strive to give you the lowest possible shipping rate, and if you live further away, a Flat Rate Box might be a lower cost option, if the item will fit into one of three sizes. We always try to ship items by the lowest cost Priority Mail option. In some cases we will offer Flat Rate shipping to all locations within the USA.

INSURANCE: In their efforts to make shipping rates more apparent to the buyer, no longer allows us to offer insurance as an option to the buyer. We may now add a small "handling fee" to the shipping cost that is equal to or less than the insurance fee charged by the Post Office. Parcels will carry USPS insurance at our discretion.

INTERNATIONAL SHIPPING: We love to ship items all over the World, but the Priority Mail shipping costs can be high. Smaller items, under 4 pounds boxed, and meeting certain size requirements can be shipped at a much lower cost using the First Class Mail International Service. However, First Class Mail can not be insured and provides no tracking number. Once it leaves our hands, we will have no way to determine if it has been delivered or not.

If you would like the First Class Mail option (for smaller, less expensive items only), email us before the sale ends and tell us that you are willing to accept all responsibility for loss or damage in transit. Only then can we give you a quote on First Class Shipping cost. No refunds on items shipped First Class.

BOTTOM LINE: If you have a question about shipping, email us and we will try to answer it.
