A cutting or sawing machine () comprising a machine body (), at least one disc shaped, rotatable tool (), an elongated tool carrier () having the substantial shape of a flat bar having a front end and a rear end, two opposite broad sides and two opposite edge sides, said rear end being connected to the machine body. The tool carrier comprises at least two elongated side walls (), a first elongated side wall () on one broad side of the tool carrier, a second elongated side wall () on the opposite broad side, said first and second side walls being essentially parallel with each other, and the front part of either one of the side walls or of a possible central elongated member () between the first and second side walls is provided with a bearing hole () intended to carry a bearing of sliding contact type or of rolling contact type, i.e. a rolling bearing, and the two side walls and the possible central member being connected to each other at a plurality of sites, and each side wall () has a length adapted to essentially cover at least the gap between the machine body () and the perimeter of its associated disc shaped tool (), i.e. the tool located on the same side of the tool carrier, so that from each broad side the side wall () and the associated disc shaped tool together cover the power transmission to increase safety and reliability.

Cutting or sawing machine

A rotatable cutting tool unit of a tool assembly for a cutting machine that is used in conjunction with an associated method of cutting provides several novel aspects. The tool arrangement, which includes two tool units, includes first and second disk-shaped tools rotatable about an axis. The tools define maximum tool arrangement boundaries along the axis. A driving arrangement, at an axial location between the first and second tools, supports the first and second tools for rotation and transfers driving force. A radially outer periphery of the driving arrangement is at a radius less than a radius of a peripheral cutting edge portion of the first tool and less than a radius of a peripheral cutting edge portion of the second tool.

A drilling machine includes a motor housing, a gear box housing, a shaft driven by the motor and extending into the gear box housing, a drilling shaft extending through the gear box housing and having an outgoing channel arranged in the drilling shaft for supply/removal of a drill flow medium to/from a tool part that is connectable to the drilling shaft, a drill flow medium room, between the motor housing and gear box housing, that can be supplied with drill flow medium when the drilling machine is in operation, and an incoming drill flow medium conduit for the supply/removal of the drill flow medium to/from the drill flow medium room. The motor housing includes a detachable end cover which forms the rear unit of the drilling machine. The gear box housing includes a detachable end cover that forms the front unit of the drilling machine.
