There are 4 types of handles: type 1 (button handle), type 2 (push handle), type 3 (four-pull square handle), type 4 (double push steel handle), type E (double handle), type F (four-drawn handle), type G (square handle), type H (square handle), type 1 (square handle), type J (interlaced handle), type K (spider handle), and type S (national digging chain handle). The type of parts shall be recorded as required (the specifications of which shall be in accordance with the requirements of 4.3). The position tolerances of electric drill bits are given in Table 2.

5 Material and hardness
5.1 The hardness of the electric pin can be alloy! According to the provisions of 1B/T 8369, 8g4
5.2 The body and material of the electric pin shall be made of C or other brands with the same performance as above, 5, 3: The electric pin shall be heat treated from the bottom of the blade (mm) to the vehicle body, and its hardness shall not be less than 0HR. The surface roughness of the target is
2-10~3
6.1 The electric drill bit can be semi-solid, and there should be no cracks, scratches, slag, pores and penetration. That is, the cutting blade should not have any defects that affect the performance. 6.2 The upper limit of the surface performance of the electric drill is as follows: the front and rear R of the electric drill bit are broken. 12.5r::

7.1.3 Test materials: The test materials are authorized by G date 110. Use Lu Ze condensation 1 other materials of the same quality, 7.1.4 Test specifications: The performance test of the electric evaluation light is at a speed greater than 25/ mim, select the drilling rig with the number of blows greater than 200/min, the hole depth of each blow of the electric hammer is (/, the hole depth of the weak accumulation is 0.5t.7.1.5 Test force: The electric chain drill after the test should have no core, desoldering, cracks and other phenomena. If the performance does not meet the above requirements, the energy test of the electric lithium drill is judged to be qualified.
