I want to buy an electric drill with requirement is about 3MM bit penetration with ordinary bowl to eat what to buy an electric drill to much power and strength
The key is to fight through the bowl bowl bit, because of high hardness, ordinary drill is not moving, you can drill glass to the hardware store to buy 3mm, the diamond, the price of two or three yuan 1. The electric drill does not need high-power, ordinary 6mm flashlight can drill, remember to add water when drilling, or the drill will be accelerated because of overheating wear.
Upstairs said good, the key in the drill bit. But the speed of the electric drill must be high, the line speed is fifty or sixty meters per second. The drill shall be ground into the negative rear angle, and no water can be added. No water can be added halfway. You can't stop over.
At present, domestic electric drill clamping diameter to 10mm. The power in the 300W-750W range, but also with positive and reverse stepless speed, to your requirements for the use of 300W single direction can speed drill start steady good control, the price is slightly high. When punching to clamp is glass hole, mounted on an electric drill, follow light pressure in vertical direction, and the water cooling in the drill point. Main point: the workpiece must be fixed to the vertical force, the drill hole can not be aware of, suddenly shaking or will cause cracking of porcelain. For bulk opening, the best selection of drill. Optional hand drill type: J1Z-6A 230W 6mm J1Z-10A 300W the clamping diameter; and the clamping diameter above 10mm; J1Z-FF02-6A 230W reversible variable speed clamping diameter 6mm; JIZ-FF-10A reversible variable speed 300W and above the clamping diameter of 10mm. Add water tools can be an empty beverage bottle, a small hole in the bottle cap, after irrigation, gently pinch the bottle body, the water will be shot to the drilling hole, it is best to operate two people in order to ensure safe and smooth.
