I have found the step drill bit to be a valuable tool with its ability to replace numerous twist bits, deburrers, and reamers. There are a number of reasons you should use a step drill bit for drilling into sheet metals.
I have compiled a list of reasons I recommend every DIY enthusiast to add step drill bits to their toolbox.
Multiple Diameters: With multiple diameters, a step drill bit saves you from the hassle of changing drill bits when you need to drill a lot of holes of different sizes. You can use a step drill bit to drill holes of different diameters.
Selt-tapping tip: Step drill bits have self-tapping tips, which allow you to drill without drilling a pilot hole in thin materials.
Flute: Flute on a step drill bit allows for easy removal of waste materials which prevents clogging as well as heating up of the drill bit.
Reaming: Step drill bit gives you smooth edges on the holes instantly thus eliminating the need for a reamer.
Deburring: You can also use a step drill bit to deburr the hole you have drilled by lightly touching each side of the hole with bevel of the next step.
And although step drill bits have a range of benefits, there are a few downsides as well.
Twist Drill Bit
The geometry and sharpening of the cutting edges is crucial to the performance of the bit. Small bits that become blunt are often discarded because sharpening them correctly is difficult and they are cheap to replace. For larger bits, special grinding jigs are available. A special tool grinder is available for sharpening or reshaping cutting surfaces on twist drill bits in order to optimize the bit for a particular material.
Manufacturers can produce special versions of the twist drill bit, varying the geometry and the materials used, to suit particular machinery and particular materials to be cut. Twist drill bits are available in the widest choice of tooling materials. However, even for industrial users, most holes are drilled with standard high speed steel bits.
What type of wood drill bit should you use for what job?
Drilling a hole into a wooden plank isn't an impossible job even for the beginning DIY-er. On the other hand, there's drilling wood and there's drilling wood. Are you screwing a few planks together, or are you building an entire garden shed? These jobs call for different types of wood drill bits, since they come in all kinds of shapes and sizes. After reading this article, you'll know exactly which wood drill bit you'll need for your job, so you're guaranteed a nice result.
Circular saw blade is an important tool and is widely used in wood industry. Its stability, cutting precision, and material-saving ability are the most important features, especially for wood processing industry because of the shortage of precious wood. The Chinese government strongly supports the improvement of timber utilization. Therefore, circular saw blade is becoming thinner and thinner currently for reducing kerf loss and improving the utilization of materials.
However, thermal stress is produced when circular saw blade is working, because the temperature at the edge of the blade is higher than that in other regions of the blade. It will cause high tangential compressive stress on the edge of the circular saw blade, causing a buckling deformation that reduces cutting precision, increases kerf loss, and shortens the saw’s life. Thin circular saw blade is more easily affected by thermal stress. For saving materials, the stability of saw blade is very important, especially for thin circular saw blade.
