A cutting tool comprising at least one blade arranged at an axial cutting head end of a tool carrier. The tool carrier comprises a chip-removal space that receives material chips removed by the blade. In some embodiments, the blade is adjacent to a chip passage feeding into the chip-removal space, which passage is limited by a radial chip gap partially limited by the blade and from there by a first and second passage surface, the first passage surface a continuation of the chip surface of the blade, the second passage surface running at an angle and widening relative to same, and is closed and limited at least in an axial sub-section facing the cutting head end, all around by a peripheral wall as a third passage surface, wherein at least one coolant channel is formed within the peripheral wall, which is provided to guide coolant to the cutting head end.

A drilling end effector is provided for drilling a workpiece having a workpiece surface. The drilling end effector includes a chuck configured to hold a drilling tool, and a nosepiece configured to at least partially surround the drilling tool when the drilling tool is held by the chuck. The nosepiece includes an end portion, at least one suction cup, and at least one suction feed line. The at least one suction cup is fluidly connected to the at least one suction feed line that is configured to be fluidly connected to a suction system. The at least one suction cup is configured to be engaged in physical contact with the workpiece surface and pulled under suction by the suction system such that the at least one suction cup adheres to the workpiece surface to thereby hold the end portion of the nosepiece on the workpiece surface.

A machining operation generating unit analyzes a program in accordance with a machining program stored in the storage unit and causes the machine tool to perform a normal machining operation. A chip removal operation generating unit outputs an instruction for rotating a main shaft in the reverse direction to the interpolation unit after a cutting machining performed by the machine tool ends. The chip removal operation generating unit rotates the main shaft in the reverse direction for a predetermined time.

A drilling apparatus comprising: at least one bit; a vacuum shroud, including a compressible boot, disposed around a longitudinal axis of the apparatus and configured to be in operative communication with a vacuum attachment port; and at least one magnetic element disposed near a distal end of the apparatus and configured to attract metallic debris resulting from drilling apparatus operation.

A dust collector can be used with a hand-held power tool. The dust collector includes a housing, a telescoping suction pipe coupled to the housing, and a suction fan positioned within the housing and operable to generate a vacuum in the suction pipe. The suction pipe is configured to telescope toward and away from the housing. The suction pipe includes an outer pipe supported by the housing, and an inner pipe slidably received into the outer pipe.

The disclosed embodiments provide a novel and unique apparatus and method to remove swarf from a workpiece during the operation of a machine tool on that workpiece. In a preferred embodiment, a set of slanted vanes attached to a rotating part of the machine tool, when that rotating part is directed at the workpiece, clears swarf from a workpiece during machine operation without having to add any other expensive swarf removal parts, or integrate any complicated swarf removal system into the machine tool. The vanes on the rotating part, using the motion of that rotating part, provide the required force of air to blow swarf out and away from the workpiece. Among the many different possibilities contemplated, the rotating part can be a spindle, or a tool holder, or an endmill, or any other rotating part of a machine tool pointed at the workpiece during the operation of the machine. Additionally, the set of slanted vanes can attach to an inner hub fitted around or onto the rotating part and the slanted vanes can spin free of any other parts if the composition of the vanes with any metallic or non-metallic material make the vanes sufficiently stiff to provide the necessary air force on the workpiece during the operation of the machine and the high speed of the rotating part. Also, the outer edge of the slanted vanes can connect to a shroud surrounding the vanes and thus keep the slanted vanes in the required slanted position to produce the necessary force of air on the workpiece. Additionally, O-rings can be used to fit the inner hub to the rotating part and thus provide another way to create the firm and secure attachment of the machine tool swarf removal apparatus to the rotating part.

A gun drill machine capable of shortening a margin dimension required in a gun drill as much as possible. In a free zone between a chip box and a moving spindle unit, a plurality of swing stopping devices for loosely holding a gun drill and suppressing the swing of the gun drill are arranged, and each swing stopping device is configured to freely retract from a steady action position where a swing stopping action is performed to avoid interference with the spindle unit that moves in the free zone.

An axial machining tool includes a cutter holder, a collet, a dust blower nut, and a cutter. The cutter holder has a receiving groove. The collet is extended into the receiving groove and has a containing space. The dust blower nut is sleeved on the collet and has a body, at least one blade, and a positioning element. The body has a threaded hole, a connecting groove, and at least one engaging groove. The threaded hole and the connecting groove are formed in the body and communicate with each other. The at least one engaging groove is formed on the body. The at least one blade is detachably mounted in the at least one engaging groove. The positioning element is mounted to the body and positions the at least one blade on the body. The cutter is extended into the containing space. A dust blower nut is also provided.

A gun drill machine capable of shortening a margin dimension required in a gun drill as much as possible. In a free zone between a chip box and a moving spindle unit, a plurality of swing stopping devices for loosely holding a gun drill and suppressing the swing of the gun drill are arranged, and each swing stopping device is configured to freely retract from a steady action position where a swing stopping action is performed to avoid interference with the spindle unit that moves in the free zone.

An air discharge method for pneumatic tool and device thereof, comprising a tool body of a pneumatic tool installed with an air guide element provided with a first air vent hole and a second air vent hole, and a brake element provided with a first air guide hole and a second air guide hole that is mounted and disposed on the air guide element, When using the pneumatic tool, the adjustment element is rotated in a clockwise or counter-clockwise direction to cause the air guide element to cover the first air guide hole of the brake element, which enabling backward discharge of air and preventing dust from flying upward to facilitate drilling operations, or the adjust element is rotated to cause the air guide element to cover the second air guide hole of the brake element, which enabling forward discharge of residual shards to facilitate cutting operations.
