DEDRA WIT11014 HSS Co5 TiN 11 mm Metal Drill Bit – 135° cobalt cylindrical drill bit for precision drilling in metal

DEDRA WIT11014 is a professional HSS Co5 TiN metal drill bit with a diameter of 11 mm and a length of 142 mm, designed for precise, stable, and efficient drilling in metal workpieces.Made of high-speed steel (HSS) with 5% cobalt and the use of a TiN—titanium nitride, this drill bit offers enhanced wear resistance, reduced friction, and improved durability during operation.

Model DEDRA WIT11014 is ideal for use in a metalworking shop, service center, manufacturing facility, or for technical tasks around the house.It's a practical choice for users who expect their tools to be reliable, provide precise guidance, and produce clean holes in metal.

DEDRA WIT11014 – TiN-coated cobalt metal drill bit, 11x142 mm, for demanding applications

DEDRA WIT11014 Metal Drill Bit is designed for drilling holes in metal materials using drills and tools equipped with a chuck suitable for holding cylindrical-shank drill bits.Diameter 11 mm allows you to drill mounting, process, and structural holes, which are often needed for metalworking, repair, and installation work.

This product is made of HSS high-speed steel enriched with 5% cobalt.This design increases the drill bit's resistance to the high temperatures generated during metal drilling, which results in more stable performance and a longer tool life.This is especially important when drilling into harder steel components, profiles, flat bars, sheet metal, angle iron, or structural components.

Vertex angle 135° helps ensure precise drilling and reduces the tendency for the drill bit to “run off course” across the surface of the material.This allows the user to have greater control over the process, achieve better hole repeatability, and obtain a more aesthetically pleasing final result.This is particularly useful when drilling into materials where precise hole positioning is critical, such as when installing screws, rivets, steel pins, or fasteners.

TiN coating, 5% cobalt, and HSS steel – durability, reduced friction, and improved drilling performance

One of the most important advantages of this model is the use of a TiNcoating, i.e., a layer of titanium nitride.This coating reduces friction during operation, which helps limit heat buildup, improves cutting performance, and enhances drilling comfort.In practice, this means less resistance when drilling a hole and better chip removal from the work area.

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.

Addendum 5% cobalt strengthens the material’s structure and improves its heat resistance, which is very important in metalworking.The DEDRA WIT11014 drill bit can be used for many common workshop tasks, such as drilling holes in steel brackets, preparing screw holes in profiles, reaming metal parts, or performing repair work on machines, gates, shelving, steel structures, and technical equipment.

Thanks to the combination of HSS Co5and TiN and 135°, this product offers a good balance between durability, precision, and efficiency.This drill bit helps reduce downtime caused by rapid tool wear and improves the quality of the holes drilled.

Where is the DEDRA WIT11014 drill bit installed, and with which devices is it compatible??

DEDRA WIT11014 is mounted in the drill chuck of a drilling machine.The drill bit has a cylindrical shank, so it fits standard drill chucks used in many corded drills, drill/drivers, and bench drills, provided the chuck’s range allows for securing a drill bit of the given diameter.

The cylindrical shank allows for quick and easy insertion of the drill bit into the tool.Before starting work, make sure the drill bit is mounted straight, securely, and properly tightened.Proper mounting reduces wobble, improves precision, and enhances safety during use.

In everyday use, the drill bit can be mounted in a drill when drilling holes in metal angle brackets, hollow sections, steel components of workshop furniture, sheet metal, hinges, brackets, or mounting structures.It's also great for drilling holes for screw connections in a workshop, garage, on a construction site, and during maintenance work.
