Use: Stainless steel / mould steel / aluminium alloy / cast iron / copper / plastic / wood etc.
Note: 1. The larger the diameter of the drill, the slower the required speed.
2. The shank of the drill is consistent with the drilling diameter.
Tips for electric drilling operations:
1. Drill the hole with the drill bit and the stainless steel plate at 90 degrees to the vertical.
2. If the hole is larger than 6MM, use a 3.2MM-4MM drill bit to make a small hole, and then use a larger drill bit to ream the hole.
3. The drill chuck must be clamped to the double-ended drill, the shorter the exposed part the better, and the edge of the drill bit does not need to be too sharp, too sharp.
4. The speed of the drill should be 800-1500 between the effect is good, the number of revolutions should not be too large, burn the drill bit, produce annealing. Stainless steel plate annealing, do not want to drill at the back
