HSS Cobalt Drill Bit Set for Metal Stainless Steel Cast Iron Wood

Take care to cool down

· When you drill deeper and deeper, the temperature at the bottom of the material will become higher and higher. At this time, reducing the speed and injecting water will have better cooling effect

· The use of water to cool the drill bit in the work process will visibly extend the life of the drill bit

HSS Cobalt Drill Bit Set for Metal Stainless Steel Cast Iron Wood

Vertical operation

· Try to stay vertical when you work with a hand drill

· Vertical operation can make the blade tip evenly stressed, which can avoid damage to the blade tip due to uneven force

· When drilling hard metals such as stainless steel and other hard metals, vertical operation is very important, and conditions permitting can use a bench drill to work, which is more efficient and will not damage the drill bit

Pay attention to control speed and pressure

· When drilling hard metals, use low speed and low pressure drilling methods

· The thicker the material to be drilled, the lower the rotational speed is, and the larger the diameter of the drilled hole, the lower the rotational speed is.

· When drilling hard metals, if the speed and pressure cannot be controlled in place, even the best drill will be damaged

Precautions of HSS Drill Bits

· When using the handheld drill, keep the drill with the drilling material vertically

· During the drilling process, you need to inject the coolant to cool the drill. If there is no coolant, water or oil is all possible, timely reducing the drill temperature can extend the drill life

· When you drill on the stainless steel, you should adopt a high pressure and low speed method. You can first use a tool (nail or open -hole) on the surface of the stainless steel. Turn the drill, remember not to drill the hole all the time, this is very easy to damage the drill bit. You need to drill for a while and then stop and inject the coolant. After the drill bit cools down, continue drilling,doing this allows you to get the most out of your drill

· If you need to drill large quantities of stainless steel, it is better to choose a bench drill to drill

· When the equipment is better, the higher the processing hardness of the processing, the more you can use the full performance of the drill.

· There is no drill bit that will not wear. We can only ensure that our drill bit will not be broken and damaged in the operation project.However, if you have equipment for sharpening the blade, when the top of the bit becomes dull due to wear, you can use the sharpener to sharpen the top edge of the bit and continue to use it until the whole bit is consumed
