Like its name implies, high carbon steel don’t corrode or weaken under intense drill heat like its counterpart low carbon steel does. Low carbon steel drill bits are commonly used for drilling holes through softwood and hardwood, and rarely for hard metals. Low Carbon Steelĭrill bits made of low carbon steel are made from as little as 0.005 – 0.3% carbon, and require constant sharpening and polishing, which is why they are inexpensive to purchase so you get what you paid for. While cobalt steel can withstand high temperature while drilling through stainless steel and hard surfaces, it is actually less durable than high carbon steel. To truly understand the kind drill bits that are made of cobalt steel, simply examine the nickel in your pocket. So, there are metal, woody bits, and many others.Īs an attempt to aid in a clear up all confusion, as well as provide general understanding of drill bits, heres an outline of the three common steels the drill bits are composed of. The length provides the depth of the hole that you are going to do with this bit. The length of the bit is not part of it, but it has a big effect on the bit’s performance. It will allow you not to damage the thread. In that case, you need a bit with a small point angle.Īnd the last part – the angle of the lips – is needed to adjust the support for the cutting edge. When working with the solid material, you need to select a bit with a large point angle. Such a part as a point angle is not less important part of the bit than the spiral part. Need a low rate of chip cleaning? Use a slow spiral. If you want to remove the shavings from the material quickly, then you need a fast spiral. The spiral part is the most important part since it is this part that is used for control during cleaning of the bit from chips. As a rule, it has a spiral part, a point angle, and a lip angle. The structure of the drill is not complicated. In accordance with this, we can get holes of any size and model if we use a drill. The drill creates round holes, despite it happens in different shapes and sizes.
The drill is a cutting (drilling) device, which finds application in creating holes in a material. Unfortunately, it isn’t until its time to redecorate the kids room, or buy new furniture that drilling equipment become a MUST have.Īfter realizing we are in need of drill tools, most DIY, new tools buyers find themselves clueless as to what function each individual drill bits delegate, as well as the specific type of steel component to buy. We will describe all of them here.ĭrilling tools are essential, and should be found in every modern home.įrom the chairs, tables, cabinets and every other equipment’s in our home, everything were all just pieces of woods and metal till we decided to pull out the tool boxes, power drills and drill bits and piece them all together. There are many different types of drill bits in the market.
