A boring device according to one embodiment of the present invention includes: a cutting edge; a drive unit that rotationally drives the cutting edge; a feed flow path through which a cooling liquid is fed to the cutting edge; and a tube pump that forces the cooling liquid in the feed flow path to flow to the cutting edge. The tube pump includes a feed tube constituting a part of the feed flow path and a first pressing mechanism that presses the feed tube, and the first pressing mechanism is driven by the drive unit.

The invention proposes a tool and device, with the aid of which it is possible to remove the surface of walls, ceilings and floors also in the corners of contaminated interiors.

A system for reducing dust when flush-cutting concrete is described, and may include a first vacuum with a first vacuum line, a second vacuum with a second vacuum line, and a saw connected to a third vacuum line, with each of the vacuum lines fluidly connected through a Y-shaped manifold. The system may also include a cart to attach the vacuums to, the cart having an upper shelf for the first vacuum and a lower shelf for the second vacuum.

Provided are a method of full body cutting a brittle material without via the bend-breaking step, an apparatus of cutting a brittle material, a method of manufacturing a brittle material, and a cut brittle material. A method of cutting a brittle material, the method comprising: a conveyance cutting step of converging and irradiating an infrared ray to the brittle material linearly along a line using an infrared line heater while moving the infrared line heater relative to the brittle material in a direction along the line, thereby cutting the brittle material along the line.

Provided are ceramic cutting methods and equipment: a beam irradiation unit for irradiating a beam of a wavelength absorbed by a pattern formed on an upper surface of a ceramic and partially absorbed by the ceramic; a coolant spraying unit for spraying a coolant onto the ceramic irradiated with the beam, wherein the pattern is removed by heating and cooling the ceramic , and is cut by reducing thermal damage by using the stress caused by the recrystallization of an upper layer or all of the ceramic or the stress generated by the thermal expansion and contraction of the upper layer or the entire ceramic, thereby recrystallizing the ceramic by heating and cooling the ceramic , or cutting the ceramic by heating until the ceramic melts, and cooling to apply thermal stress to the inside of the ceramic, followed by an additional separation process of a ceramic material without loss.
