The greater the point angle, the harder the metal (and therefore the flatter the point). Point angle: The point angle varies depending on the drill (90°, 120°, 135°, 140°, 145°) and should be tailored to the metal you intend to drill.
These drill bits are intended for use with hammer mode screwdriver tools.įactors to Consider Before Buying Metal Drill Bits Some drill bits, such as those used with electric screwdrivers, have hex shanks.
SDS Max shanks are used for heavy-duty applications as well as with other hammer drill accessories such as flat chisels and moil points. The majority of concrete drill bits have SDS+ shanks. Most hammer drills and various brands of standard drills have this shank.
SDS drill bit: a drill bit with a grooved shank that clicks into the chuck. HSS-R drill bits are versatile and precise, making them ideal for a variety of drilling tasks. These drill bits are made through a heated rolling process in which the material is shaped between two parallel cylinders that turn in opposite directions. High-speed steel rolled metal drill bits: Roll-forged flutes are used in HSS-R bits. Ground bits are efficient and precise, making them suitable for long-term use. Their cutting edges (flutes and lips) are white rather than grey, and they are perfectly symmetrical. These bits' material is ground directly into shape using a grinder. High-speed steel ground metal drill bits: HSS-Gbits are ground along their flutes and at the tip. A set of pilot drill bits will give you a good selection of these essential tools. The pilot hole could be a counterbore, with a larger section at the top. These are made of building materials such as wood and plastic to guide the insertion of larger drills or bore-making tools. Pilot Drill Bits: Pilot drills, also known as pilot point drills, are precise tools used to make pilot holes. Among them are carbon steel, stainless steel, cast iron, titanium alloys, and composites made of carbon fibre. High tensile metals, or metals that maintain strength under tension can be utilised with cobalt drill bits. Even when cooling is scarce, the bits' 5% cobalt admixture improves strength and heat resistance. Auger drill bit setsĬobalt Drill Bits: Sets of cobalt drill bits are excellent equipment. For cutting through soil, dirt or ground auger drill bits serve the same purpose. Auger drill bits can also be used to sever ice. Types of Drill Bits for Your Commercial NeedsĪuger Drill Bits: Auger drill bits have a distinct appearance, with sharp helical spirals along their shaft known as 'flightlings.' They are intended to produce smooth, uniform holes in wood while also removing shavings. At Moglix, we sell high-end, economical metal drill bits from renowned brands such as Bosch, ANZ, Cheston, Kenzy, GE Tech and more. The material used to make drill bits determines their quality, which in turn controls their ability to drill into various materials. Bits with diamond or tungsten carbide tips can even be used to cut through glass or tiles. Drilling bits designed for metal, masonry, and wood can all be used. Depending on the material you want to work on, there are several different bit types. The shank is the top portion of a drill bit that is attached to the chuck, a unique clamp located inside the drill's main body. Drill bits are the tools that allow drills to cut holes into various materials by applying circular torque, or rotational force.
