2017-8-9 · to machine materials such as aluminum casting EN AW-5083. The squeak bespeaks the sound of tearing (shearing/ galling) aluminum when drilling these aluminum alloys. Lubricity-feed-speed are not in agreement, so metal-to-metal contact occurs, causing welding of aluminum to the drill bit –and immediate tearing (shearing).
The tightening torques are max. 50% of the minimum breaking torque. Prior test must be carried out for the utilisation of other screws or other sheet metal materials. Punched pilot holes must be 0.1 - 0.3mm larger and the screws must be tightened in the direction the hole was punched. Thread diameter. Material Strength Rm (N/mm2)
