DEDRA WIT11514 HSS Cobalt TiN Metal Drill Bit, 11.5 x 142 mm, 135°, for Steel
- HSS metal drill bit with 5% cobalt and TiN coating, DEDRA 11.5 x 142 mm, 135° angle. Durable, precise, and resistant to overheating, it ensures fast drilling in metal and reduces friction and chip buildup.
DEDRA WIT11514 is a professional TiN-coated cobalt HSS metal drill bit with a diameter of 11.5 mm and a length of 142 mm, designed for fast, stable, and precise drilling in metal workpieces.Made of high-speed steel (HSS) with 5% cobalt and coated with TiN—titanium nitride, they ensure high heat resistance, reduced friction, and a longer service life.
This product is ideal for use in a locksmith's shop, a service center, a manufacturing facility, or a DIY enthusiast's garage.Thanks to the vertex angle 135° , the drill bit starts drilling more easily, reduces slippage on the material, and produces a clean, precise hole in metal.
DEDRA WIT11514 TiN-coated cobalt metal drill bit – what is it and why should you choose it??
DEDRA WIT11514 is a single-flute drill bit designed for metalworking, created for users who expect reliability, high durability, and consistent precision.Its design is based on three key features: cobalt-alloyed HSS steel, a TiN coating, and a 135° cutting edge.This combination makes the drill bit perform very well when drilling into hard metallic materials, where ordinary drill bits can quickly become dull or overheat.
HSS high-speed steel with 5% cobalt increases the drill bit’s resistance to the high temperatures generated during intensive drilling.This is especially important when you're drilling a large number of holes or working with harder steel parts.The addition of cobalt enhances the stability of the cutting edge, allowing the tool to remain effective for longer.
TiN coating reduces friction between the drill bit and the workpiece.In practice, this means smoother operation, less heat buildup, and reduced chip buildup.The drill bit is coated with a layer of titanium nitride, which ensures a low coefficient of friction, reduces the risk of chips sticking to the drill bit, and increases drilling efficiency; it also reduces vibration and extends the drill bit's service life.
Vertex angle of 135° helps ensure a precise start to drilling.In everyday work, this means greater control over the tool, especially when drilling into sheet metal, profiles, angle irons, structural components, or flat steel bars.The drill bit "slips" less across the surface of the material, making it easier to drill a hole in the designated spot.
Where is the DEDRA WIT11514 11.5 mm drill bit installed, and with which tools is it compatible??
Drill bit DEDRA WIT11514 is mounted in the drill chuck of the appropriate power tool or workshop machine.Thanks to its cylindrical shank design , it fits standard drill chucks that allow for a secure grip on drill bits of this diameter.They can be used with hand drills, bench drills, and select workshop equipment designed for drilling in metal.
For everyday use, the drill bit can be mounted in a corded drillwhen high and consistent power is needed for drilling through steel.It will also work well with a cordless drill, provided the tool has sufficient torque and a chuck that allows the drill bit to be securely held in place.For more precise applications, it’s best to use a bench drill press, which ensures even pressure and perfect drill bit guidance.
The three most important installation benefits are: universal cylindrical mount, stable guidance through the material and easy drill bit replacement.The user can quickly prepare the tool for use, secure it in the chuck, set the appropriate speed, and start drilling.This is a practical solution for assembly, repair, installation, and manufacturing work.
For example, a drill bit can be used when installing steel brackets, drilling screw holes in structural components, preparing sheet metal for riveting, drilling into steel profiles, or fitting metal parts in a workshop.Diameter 11.5 mm allows for drilling holes for larger screws, fasteners, and technical connections.
Applications for the DEDRA WIT11514 metal drill bit – steel, metal, and workshop projects
DEDRA WIT11514 Metal Drill Bit is primarily designed for drilling in metal, including steel and steel components used in construction, repairs, and assembly.This tool is for people who need to drill a precise hole with a diameter of 11.5 mm without putting excessive strain on the drill bit or causing rapid wear on the cutting edge.
This drill bit is ideal for tasks such as preparing screw holes, reaming mounting hardware, machining steel profiles, and drilling into flat bars, angle bars, and sheet metal.It can be used in the construction of steel structures, machine repairs, the assembly of technical shelving, the modernization of fences, and the fabrication of handles, brackets, or installation components.
Three practical features that are particularly important to the user are: quick immersion in the material, minimal chip buildup and resistance to overheating.They make the work more comfortable, and the holes are neat and consistent.With the right speed, adequate cooling, and proper pressure, a drill bit can last a long time, even with frequent use.
In practice, the DEDRA WIT11514 will be useful to a mechanic repairing metal parts, a fabricator preparing holes in structures, a metalworker during everyday steel fabrication, and a DIY enthusiast who wants to create a sturdy bolted joint in a garage or workshop.It's a good choice when efficiency, durability, and drilling precision matter.
HSS with 5% cobalt and a TiN coating – durability, reduced friction, and efficient drilling
One of the biggest advantages of the drill bit DEDRA WIT11514 is the use of HSS with 5% cobalt.HSS high-speed steel is valued for its strength and ability to operate at higher cutting speeds, while cobalt improves the tool's heat resistance.This is particularly important when working with metal, where drilling generates high temperatures and places a heavy load on the cutting edges.
The second important element is the TiN coating, i.e., a layer of titanium nitride.Its purpose is to reduce friction, limit overheating, facilitate chip removal, and extend the drill bit's service life.The golden TiN coating is not only a distinctive design feature, but above all a practical reinforcement of the tool's working surface.
The three most important benefits of combining HSS, cobalt, and TiN are: longer drill life, smoother drilling , and greater resistance to heavy-duty use.This makes the tool a good choice for regular use, especially when you need reliable equipment for demanding tasks.
In everyday use, this means fewer stoppages, less frequent drill bit replacement, and greater confidence that the hole will be drilled precisely.When drilling into steel structural members or thicker profiles, it is important that the tool remains sharp and stable.The DEDRA WIT11514 was designed specifically for these types of tasks.
135° point angle and 11.5 mm diameter – precise holes in challenging materials
Vertex angle 135° This feature is valued when drilling in metal because it facilitates centering and reduces tip slippage on the surface.Compared to less aggressive geometries, this angle allows you to start drilling faster and control the tool more effectively.This is especially important when drilling holes in smooth, hard, or slippery steel components.
Diameter 11.5 mm makes the drill bit suitable for drilling larger technical holes, such as for screws, sleeves, pins, fasteners, or structural connections.Total length of the drill bit 142 mm ensures comfortable use for many common workshop and assembly tasks.
The three factors that affect drilling quality are: stable guidance, precise hole diameter , and vibration reduction.The drill bit produces a cleaner finish, which is important when assembling components that require a tight fit.Holes drilled with greater precision make it easier to screw, rivet, or fit parts together later.
Examples of practical applications include drilling holes in a steel frame, preparing a flat bar for bolted assembly, drilling through a metal profile when building a workshop rack, or adjusting structural components during machine repairs.In each of these cases, what matters is precise guidance, drill bit durability, and consistent results.
