To compensate for the brittleness ofcemented carbide to increase its cross-break strength, the ratio of the diameter (c) of the web portion (1) to the drill diameter (d) is set in the range of 25% to 35%, and the flutewidth ratio (b : a) is set in the range of 0.4 : 1 to 0.8 : 1. Further, to decrease the cutting resistance on the drill, the radial rake (o,) angel of the cutting lip (4) measured at positions spaced at least 213 of the drill diameter toward the outer peripheral side is set in the range of -5° to positive. Furthermore, to promote the chip ejecting function, the relative distance (L) between the cutting lip (4) and the flute wall (5) opposed thereto is decreased.申请人：SUMITOMO ELECTRIC INDUSTRIES LIMITED地址：No. 15, Kitahama 5-chome, Higashi-ku Osaka-shi, Osaka 541 JP国籍：JP代理机构：Patentanwälte Kirschner & Grosse更多信息请下载全文后查看。

The bit body 10 has a flange portion 13 which includes a converging portion 13a which reduces its diameter progressively towards the front end of the bit body and a flange 13b which is provided with a rearwardly facing annular surface 13c. The annular end surface iscontactable with the front end surface of a drill holding portion of a machine too. Chip discharging flutes 14A,14B, each having an inner surface constituted by first and second inner surface portions 14a,14b and a third inner surface portion 14c arcuately recessed therefrom, are formed in the front end portion of the tip body 10. An inner peripheral cutting insert 16A and an outer peripheral cutting insert 16B are mounted on the ends of the chip-discharging flutes 14A,14B. The cross-sectional area SA of the first-mentioned chip-discharging flute 14A is determined to be greater than that SB of the second-mentioned chip-discharging flute 14B. A plurality of grooves 25 are formed in the third inner surface portion 14c so as to extend along each chip-discharging flute.申请人：MITSUBISHI MATERIALS CORPORATION地址：6-1, Ohtemachi 1-chome Chiyoda-ku, Tokyo 100 JP国籍：JP代理机构：Türk, Gille, Hrabal, Leifert更多信息请下载全文后查看。

CONSTITUTION:A drill 2 in a diameter of 0.2mm or less provides between its edge part 11 and shank part 12 a successively connecting part (tapered part) 21 with a uniform rate of increasing its external diameter. And a curved surface part 22, smoothly connecting its peripheral surface, is formed between the successively connecting part 21 and the edge part 11. Accordingly, the drill, decreasing a section change rate to a small value, prevents stress concentration from being easily generated while easily obtains the concentricity in a manufacturing process. Consequently, the drill can reduce its damage and flection simultaneously improve straightness and out of roundness of a drilled hole.申请人：MITSUBISHI METAL CORP更多信息请下载全文后查看。

CONSTITUTION:Tip end cutting edges 3 cut the bottom surface of a drilled hole, and simultaneously, outer peripheral cutting edges 20 cut the inner wall 100 of the drilled hole. Further, during the above-mentioned drilling, even though heat generation due to the cutting causes the forward end of the drill to expand, the outer peripheral cutting edges 20 cuts into the inner wall 100 of the drilled hole only by a degree corresponding to the expansion. Thus, during deep drilling, no rotating resistance is increased so that the drill may hold a satisfactory cutting performance for a long period, thereby it is possible to increase the life of the drill.申请人：HOSOI TOSHIAKI更多信息请下载全文后查看。

CONSTITUTION:When the diameter of a cutter 6 is taken at 'D' in the rotary locus formed on the tip flank 5 of a drill body 4, diameter D1 aft of a range of 0.2-2D from the peripheral edge of the cutter 6 toward the aft side thereof is taken at 0.92-0.98D. When drilling work is carried out with the whole drill in a bent state, the aft end periphery thereof does not come in contact with the internal wall of a hole and an accident such as a drill fracture can be prevented in a drilling process with a workpiece under rotation. Also, as the whole drill is liable to be flexible, the centripetal effect of the drill becomes easy to appear in drilling and furthermore deep hole drilling can be made with out any loss of guiding quality.申请人：MITSUBISHI METAL CORP更多信息请下载全文后查看。

When drilling work is performed with this drill, the chips are generally curled and can be smoothly discharged without being excessively abutted against the wall surface (4, 9) of the chip discharge flute (3); consequently, the chips can be smoothly discharged, and the drill main body (1) is subjected to less frictional resistance, which leads to less wear on the drill and less driving torque for drilling. Therefore, the drill life can be preferably extended even under severe drilling conditions, such as during high speed drilling, and smooth and stable drilling can be performed.申请人：MITSUBISHI MATERIALS CORPORATION地址：5-1, Otemachi 1-chome Chiyoda-ku, Tokyo JP国籍：JP代理机构：HOFFMANN - EITLE更多信息请下载全文后查看。

CONSTITUTION:A point angle formed by two cutting edges 35 at the tip of a tool body 33 is formed in an angle from 35 deg. to 40 deg., and a drill flank is formed of a superhigh pressure sintered body made of diamond from a chisel part at a tool tip to an end on the outer peripheral side of the tool and to the depth of about 0.7mm from a flank surface, and the above-mentioned superhigh pressure sintered body is fixed on the tool body 33 by brazing. Thus, in this drill 31, the point angle restricted as mentioned above can prevent the occurrence of an exit burr at the passing through edge of hole, and the superhigh pressure sintered body formed on the flank surface can improve the life of the cutting edge 35, and moreover its formation extending over the whole flank surface and having the above-prescribed depth can simplify drill regrinding work, and apply the cutting edge again to a machining process.申请人：MITSUBISHI METAL CORP,MITSUBISHI HEAVY IND LTD 更多信息请下载全文后查看。
