The Hex Shank
The hex shank drill bit set is available in a number of different types. With a 120-piece Master Drill and Driver set, it includes a quick-connector, hex-shank twist bits, spade bits, masonry drill bits, pilot-hole bits, numerous drivers as well as other accessories. A few manufacturers offer their cabinetmaker bits with self-centering bits, tapered drill bits as well as countersinks.
The new SpeedFit 2-in-1 connector is able to load all hex shank accessories. It is a very quick and easy one to use. The titanium coating on the hex shank drill bit set is able to reduce friction as well as increased drilling speeds in metal. In addition, you are able to get this popular assortment of drilling and driving accessories in a tough and compact case.
Sizes of Hex Shank
A typical hex shank drill bit set consists of titanium hex shank drill bits, which come in various sizes such as 1/16″, 5/64″, 3/32″, 7/64″, 1/8″ and 3/16″. Additionally, there are assorted 1 inch and 2-inch hex shank inserts driving bits. Also included are nut setters of 1/4″, 5/16″ and 3/8″. It is recommended to always wear safety glasses while using this drill bit set or any time you use your drill to protect your eyes.
The 18-inch Fluted hex shank heavy-duty auger bit is required mostly in construction. These are precision machined in order to provide smooth and wobble-free boring. These have a wide and large throat that is doing an efficient chip clearance for long or deep holes. The hardened cutting edges will also require less of re-sharpening. Auger bits are not designed to cut holes that are accurately sized. As a result, you will always have an oversize clearance hole.
You will come to realize the longer you work with your drill, that you really can’t have too many drill bits. You need them for numerous around-the-home, shop as well as contractor chores. Bits are needed for drilling just about any and every material, such as wood, various metals, concrete, tile, stone, and even glass.
Helix and Flute Angle
The helix and flute angle drill bits are also important and can be purchased in a hex shank drill bit set. These days there’s a lot of variety to choose from, depending on the job requirement. The new Helix design has an aggressive flute structure that is engineered in order to remove material faster. The 135-degree split point is meant to eliminate walking which makes the bit much more efficient. A Quick penetration means less energy on the part of the drill that one is drilling the bit and the user who is operating it. This helps battery life of a cordless drill as well as reduce fatigue failure on the part of the user.
Why Hex Shape Extension
Today almost universal modification of handheld electric drills has taken place. Hence the chuck is tightened by hand instead of using a key. But invariably with a short period of usage, the drill bit quickly comes loose. This can be remedied in case you use a hex base on the bit. This has today become common on various sized screwdriver bits. The average drill bits set come with a cylindrical base but it is highly prone to slippage. In case drill sets having hex bases are not available, you may even purchase a hex base separately. The standard bit could be inserted into this and permanently fastened by using a solder or any other kind of epoxy glue.
In case a standard-sized hex socket is used instead of using a chuck, all the drills can have the same sized hex base. This can be magnetized in order to allow for easy insertion as well as removal with no gripping mechanism required on the drill bits set.
Another option is a simple cross-sectional shape of the drill bit shank. This would prevent revolution as a square or hexagonal shape is sufficient without incorporating the fussiness of a set screw. And once the magnetization of the socket in the drill is done, it will keep the bit in place and make it easy to insert and to remove. A shank that is threaded would make the drill held so firmly after the rigor of drilling that you would require a wrench or pliers to remove it. This is basically an additional complication that is both unnecessary as well as clumsy.
One of the reasons that round drill bits set are made is because of the safety factor. This way the drill bit becomes more prone to slip when it is stuck instead of just breaking. In case the bit gets stuck and breaks at high speed, it could result in flying shrapnel which may lead to some serious damage. In case of drill bits snapping, the resulting failure would never result in shrapnel, but merely a broken drill end which can be removed with a pair of pliers.
The drill bits set with hex bases are commonly available today along with the quick-change type chucks. But the only issue is that these hex-based drill bits are not available in combination with magnetic hex drill chuck sockets. This is because the quick-change chucks are friction grasp based on round drills though they could be used with the hex-based bits too. The fact is that a magnetic hex chuck as well as hex-based bits are available today but have a limited number of drill bit sizes.
Wrapping it Up
In case you are drilling, and you find the drill spinning, it means that you are using the wrong tool. You need to use the correct drill bits set. Move up to a drill that is using a key chuck. Beyond that, you will need to use a core drill.
