Benefits of technology

"The present invention provides a sanding bit for use with an electric drill. The bit consists of an elongated member with a drill shaft and a slot on the other end. The slot is designed to hold a flexible sandpaper strip, which is wound around the end of the member to form multiple layers. This design allows for easy and efficient sanding with the electric drill."

Problems solved by technology

After extensive use, the grit on the sandpaper will either wear away or become clogged and will have to be replaced.
This type of sanding device is very popular; however, it can only be used on large flat surfaces because of the size of the circular pad.
Unfortunately, these stones have a relatively small surface area, which in turn means that they wear out relatively quickly.

Embodiment Construction

[0016] Referring firstly to FIGS. 1, 2 and 3, the sander attachment, shown generally as item 10 consists of a barrel member 12 coaxially mounted to a drill shaft 14. Shaft 14 is dimensioned and configured to releasably mount to chuck 16 of electric drill 18. Barrel 12 has slot 20 which bifurcates the barrel. Slot 20 is dimensioned and configured to receive elongated sandpaper strip 22. Sandpaper strip 22 is preferably rectangular and has ends 24 and 26 and has abrasive surface 28. Sandpaper strip 22 is suitably flexible to permit it to be wound around barrel 12. Slot 20 is dimensioned and configured to snugly receive end 24 of sandpaper strip 22. Sandpaper strip 22 is wound around barrel 12 with abrasive side 28 oriented away from the barrel member. Barrel member 12 and drill shaft 14 are preferably made from a strong material such as steel or brass. Preferably, drill bit 10 may be made from a single piece of metal such that barrel 12 and shaft 14 are contiguous.

Abstract

The present invention is a sanding bit for use with an electric drill. The bit consists of an elongated member having a drill shaft formed on a first end of the member and a slot formed on a second end of the member. The slot is dimensioned and configured to receive an elongated strip of flexible sandpaper. The sandpaper strip is wound around the second end of the member to form a plurality of layers around the second end of the member. A barrel portion is formed on the second end of the member, the barrel portion having a greater cross-sectional diameter than the shaft. The slot may bifurcate the barrel member. The barrel portion may be cylindrical or conical.

Description

FIELD OF THE INVENTION [0001] The invention relates generally to drill attachments for use in sanding. BACKGROUND OF THE INVENTION [0002] There are numerous attachments and bits for use with electric drills. In addition to drill bits, electric drills can be used with grinding, cutting and sanding attachments. Drill bits which are designed for use as sanders are well known in the market. These sanding attachments generally come in two different forms. The first form consists of a circular pad mounted to a drill shaft. The drill shaft is inserted into the chuck of the drill and a circular piece of sandpaper is attached to the circular pad. The sandpaper is usually attached to the pad by means of either an adhesive or by means of a recessed flanged bolt at the center of the pad. When the drill is activated, the circular pad spins allowing the user to sand down an item by applying the sandpaper covered pad to the item. After extensive use, the grit on the sandpaper will either wear away...
