摘要： A gundrill and a method of forming deep holes using such a gundrill having an elongate tubular shank 242 and a cutting tip 244 with a novel profile is disclosed. The cutting tip 244 and tubular shank 242 are both provided with a tubular central region supplying pressurized drilling fluid and a non-circular fluid cross-section which defines a drilling fluid return path in conjunction with the bore of the hole being formed. The cutting tip cooperates with the bottom of the hole being formed such that the cutting tip 244 and the bottom of the hole form an outlet. The outlet size is carefully controlled in order to maintain relatively high drilling fluid pressure in the bottom end space and the flow of drilling fluid discharged from the end space is controlled to cool the cutting surfaces and to effectively remove chips as they formed.

摘要： A drill bit (10), particularly for cutting deep holes in hard materials, includes a tubular shank (12) with a solid center (20) and diametrically opposed coolant conduits (14,16) which supply coolant to a tungsten carbide tip (32) located on one end of the tubular shank (12). Swarf and debris are carried by the coolant away from the cutting area and along swarf clearance channels (22,24) located along the exterior of the shank tube out of the borehole. The carbide tip (32) is brazed to the tubular shank (12) and is formed with a pair of angularly spaced tubular chambers (44,46) which communicate with the coolant conduits in the shank. One cutting edge (34.361 is provided on top of each chamber in the tip. A coolant hole (48) is formed at the top of each tubular chamber (44,46), behind the cutting edge (34,36). The coolant which emerges from the tip (32) flows to the space between the tubular chambers (44,46) and carries with it the swarf along the swarf clearance channels (22,24) defined by the shank out of the borehold.

摘要： The present invention provides a hole drilling process and a drilling tool. The hole drilling process is for drilling a hole on a supported tube sheet (45) by using a first drilling tool (63a) that can drill a hole with a diameter smaller than that of a mounting hole (60) that is to become a target hole, and a second drilling tool (63b) that can drill a hole with a diameter equal to the diameter of the target hole, the process including: a temporary hole drilling step in which a temporary hole (60A) with a predetermined depth set beforehand is drilled by moving the first drilling tool (63a) to a drilled position set beforehand; a hole measuring step in which a distance (S) between an existing mounting hole (60) and the temporary hole (60A); a drilled position correcting step in which the drilled position is corrected based upon the distance (S) between the mounting hole (60) and the temporary hole (60A); and a target hole drilling step in which the target hole is drilled by moving the second drilling tool (63b) to the corrected drilled position.
