It is necessary to point out that the covered end thickness of back covered porous brick is increasing as the machine wearing , and it results in the decreasing pore space ratio 但是，由于盲孔多孔砖机冲头不断磨耗，如不及时更换，将使盲端厚度随之增大，致使砖的孔洞率降低。
But it is possible to reduce the shear " resistance and aseismatic ability when back covered porous brick builds the brickwork because it has not the " pin " formed by the masonry mortar leaked into the hole 但由于是盲孔，砌筑时没有因漏浆而形成的“销键”作用，可能会降低砌体的抗剪能力，不利于抗震。
This holder doesn ' t only meets the requisites of a conventional quick change chuck ( capacity / weight / dimensions ) but also has the advantage of being an excellent tapping device with pre - adjustable torque 显然这种带扭力保护的攻丝夹头适用于各种不同的攻丝操作的平台例如：打盲孔、直径很小的、很坚硬的工件或者是当丝锥损耗的很严重的时候。
Obviously this torque avoids breaking of the tap in difficult tapping operations such as tapping blind holes , very small diameters , very hard and resistant materials or when the tap is excessively worn out 显然这种带扭力保护的攻丝夹头适用于各种不同的攻丝操作的平台例如：打盲孔、直径很小的、很坚硬的工件或者是当丝锥损耗的很严重的时候。
