Surely many people are familiar with a situation when during work it becomes necessary to clearly limit the drilling depth, of course you can use electrical tape, but it quickly becomes unusable, shifts, and restricts the drill movement only "by eye", so it’s safer and better to turn to snap rings specially designed for such work are also called drilling stoppers. They are rings made of high-quality high-carbon steel with fixing screws. An important feature is that the drill is not damaged during fixation.
For reliable fixation of the drilling depth, it is enough to measure the required depth on the drill, place the ring on the marked position and fix it by tightening the fixing screw with the included hex key.
The product package is as follows:
• 1 ring with a diameter of 3 mm;
• 1 ring with a diameter of 4 mm;
• 1 ring with a diameter of 5mm;
• 1 ring with a diameter of 6 mm;
• 1 ring with a diameter of 8mm;
• 1 ring with a diameter of 10 mm;
• 1 ring with a diameter of 12 mm;
• 1 ring with a diameter of 16mm.
Thus, for a completely ridiculous price, you will never have to fear that the depth gauge will shift, slip or melt due to a heated drill during operation, and you can also forget about manufacturing “on the knee” of various depth gauges. In a word - working with such devices will be a pleasure for you.
