5 Technical requirements
51 The material of the drill is 45# high-quality carbon structural steel specified in CB699 and is made of other materials not lower than the technical requirements specified in the standard:
5.2 The wood drill blade should be sharp and should not have dull mouth, burnout, curling and other phenomena. The vertical edge should be high → cutting edge. The two cutting edges of the double-blade drill should be even and the distance between the two edges should be low. 5.3 The hardness of the head of the drill is HRC42~5. 5.4 The spiral ribs should be thin and uniform, with a surface roughness R not less than T3.2um and a surface roughness R not less than 6.m. Cracks, Curling, flying leftovers and other phenomena. 5~13mm specifications of the drill is not allowed to have large 2mm spots and pits, 14~38mm specifications of the drill is not allowed to have large 10mm\ spots and pits 5.5 The taper of the butterfly thread is 20°3", the thread is broken, there is no crack, 5.6 The vertical blade and the can shadow screw should be on the circumference center line, the north axis angle is: 5~13mm is not more than 4mm11~z4mm is not +0.5mm: 25~38mm is not F0.6mm 5.7 The spiral reinforcement of the drill should be smaller than the outer diameter of the head, 5.8 After the drill support test: the blade and the shaped screw should not be curled, topped, or tilted. 59! The workpiece or the cup should be vertical, and the connection must be correct. Under normal use, there should be no looseness, lifting, or wrist exposure.
5. The back of the long-handled woodworking drill should be painted with anti-rust paint, the seams should be neat, and the paint layer should be uniform. The back of the woodworking drill should be painted with back paint. 6 Test method
6.1 The toughness of woodworking drills shall be tested in accordance with the provisions of GB230. Small woodworking drills below 10mm shall be tested with a standard chain knife. 61
QB/T 1736-93
6.2 The roughness of the surface of the threaded bar shall be compared with the roughness sample block of the machine. 6.3 The taper angle of the screw shall be tested with a special plate. The type and size of the special plate are shown in Appendix A (Supplement). 6.4 Drilling test
The hole test of woodworking drill and electric woodworking drill is carried out by hand on the knotless wood with thickness of 50mm and 15mm and moisture content not more than 20%. The number of holes is three. The drill chips should be discharged smoothly through the spiral groove during drilling. The technical pins after the test meet the requirements of 5.8.
6.5 The coaxiality tolerance of woodworking drill after drilling should meet the following formula: DED+A
Where: D is the actual hole diameter of the woodworking drill on the hardwood; A is the actual size of the outer diameter of the woodworking drill head;
6.6 The size of woodworking drill is checked by hand and visual inspection.
