Electric Drill Processing Operation Tips:

1: When Drilling, The Drill Bit And The Stainless Steel Plate Are Perpendicular To 900°
2: If The Hole Is Larger Than 6mm, First Use A 3.2mm-4mm Drill Bit To Drill
Small Holes, And Then Use A Big Drill To Ream The Holes
3: The Electric Drill Chuck Must Clamp The Double-headed Drill, And The Exposed Part Is As Short As Possible. The Cutting Edge Of The Drill Does Not Need To Be Too Sharp, Too Sharp
4: The Number Of Revolutions Of The Electric Drill Should Be Between 800-1500, And The Effect Is Better. The Number Of Revolutions Should Not Be Too Large, Which Will Burn The Drill Bit And Cause Annealing.
5: Before Punching, You Can Use Sample Punch (or Nails Can Be Used Instead) To Punch At The Punching Position
Center Point, The Drill Will Not Run Off
