Electric drill processing stainless steel operation tips
1. Hand-drilling drilling twist diamonds and stainless steel plates are vertical 90 °
2. If the holes are larger than 6mm or more, use the 3.2mm-4mm drill to make a small hole, then expand the bore with a large drill
3. The electric drill clip must be clamped to the anecnic drill bit, the shorter the twist drill, the better, the knife of the twist drill does not need too much, too sharp
4. The number of electric drills should be better at 80-120. The more the number of revolutions, the more you cant go, burn the bad drill, generate annealing, stainless steel plate annealing, dont want to drill behind it.
5. Turanable ground, uniform force, electric electric drill
