Abstract
A support assembly for a core drill uses an improved reinforcement. The reinforcement can include an extension extending between a center of the tool and a perimeter of the tool the extension can be a non-planar structure having a channel along a portion of the structure. The reinforcement can include a slanted element that can be associated with the extension, that can be formed monolithic with the extension, or otherwise combined with an extension. Multiple slanted elements can be used to form an extension. A top plate can be included for strengthening the reinforcement.

A drive assembly having a reinforcement structure for a tubular core drill, the drive assembly comprising a tool coupling element or hub having an axis aligned with a center axis for receiving from a first direction a drive tool element for a core drill, a structure configured for supporting a cylindrical core so that the structure supporting the cylindrical core and the cylindrical core are axially fixed relative to each other, a plurality of extensions extending from an area near a center of the tool coupling element to an area adjacent the structure for supporting the cylindrical core wherein each extension includes a rectangular planar arm extends in a plane parallel to the center axis that does not intersect the center axis.
A drive assembly for a tubular core drill, the drive assembly comprising a tool coupling element or hub having an axis aligned with a center axis for receiving from a first direction a drive tool element for a core drill, a core drill coupling element for supporting a cylindrical core, a plurality of rectangular arms each extending perpendicular to a plane normal to the center axis and contacting and extending distally in respective directions away from the tool coupling element to respective positions on the core drill coupling element and secured to the core drill coupling element.
A drive assembly having a reinforcement structure for a tubular core drill, the drive assembly comprising a tool coupling element or hub having an axis aligned with a center axis for receiving from a first direction a drive tool element for a core drill, a structure for supporting a cylindrical core, a plurality of extensions extending from an area near a center of the tool coupling element to an area adjacent the structure for supporting the cylindrical core wherein each extension includes a rectangular planar arm contacting at least one adjacent rectangular planar arm, wherein each rectangular planar arm extends parallel to the center axis and in a direction that does not intersect the center axis.
