Abstract:
A cutting tool of the specified type is to be miniaturized and configured in such a manner that it is suitable for working bores having a diameter of 6 mm and more and for high-speed work with revolving tools.The solution according to the invention provides that the adjustment screws for radially adjusting the cutting plate simultaneously form a clamping means for the form-locking clamping of the cutting plate to the supporting shoulder of the basic tool body.A preferred field of use are precision drills and grinding tools equipped with inserted cutting strips made of a highly wear resistant cutting material.
Abstract:
A ceramic stove that may be supplied in kit form includes a base frame, a cast iron firebox secured on the base frame, a top frame attached to and surrounding the top of the firebox, and ceramic panels extending between and held by the frames in spaced relation from the firebox. The ceramic panels are "ship-lapped" relative to each other and are not cemented or otherwise positively attached to each other. Logs may be fed as fuel into the firebox door from one side of the stove allowing longer logs to be burned. The logs rest on a grate which includes a "shakable" portion for shaking ashes onto an ash pan located below the grate. A separate, small door into the firebox is provided for starting the fire and that door is covered by another, safety door which also closes the space through which the ash pan is removed for emptying. An outer screen gate is provided to overlie the firebox doors and the entire side of the firebox. Products of combustion rise in the firebox and are guided by a baffle in a desired serpentine path prolonging their containment, until they reach an outlet at the top of the firebox where they are then carried downwardly by a flue formed in part by a portion of the back wall of the firebox. A heat shield covers the back wall of the firebox including the flue whose outlet extends through the heat shield at mid elevation. Other features and advantages are also disclosed.
