DEDRA HSS 4341 Metal Drill Bit, 8.5 x 117 mm, 135° – Set of 5 for Precision Drilling in Metal

HSS metal drill bit, 4341 steel, 135°, 8.5 x 117 mm, 5-pack. This is a practical set of drill bits designed for drilling precise holes in metal parts.Product by DEDRA is made of high-speed steel HSS 4341, making it ideal for workshop, assembly, and maintenance tasks, as well as home repairs.Diameter 8.5 mm allows for drilling holes for screws, rivets, metal pins, structural components, and various types of technical fasteners.

The 135° point angle enables quick drilling and reduces the risk of the drill bit slipping on the workpiece surface.This is particularly important when working with sheet metal, steel profiles, angle iron, flat bar, or other metal components, where precision, repeatability, and smooth tool guidance are essential.The set includes 5 drill bits, providing a convenient supply for more intensive use in a workshop, garage, manufacturing facility, or during installation work.

DEDRA WMT08511 HSS 4341 Metal Drill Bit – Precision, Durability, and Comfortable Drilling

The DEDRA WMT08511 metal drill bit is a tool designed for users who expect efficient drilling, stable guidance, and robust resistance to the loads typical of metalworking.The key features of this set are 4341 high-speed steel (HSS), a 135° point angle , and a universal cylindrical shank.The combination of these features makes these drill bits ideal for both everyday DIY projects and more demanding workshop tasks.

4341 HSS Steel ensures durability and the ability to operate at higher rotational speeds.This material is often used in cutting tools because it offers good wear resistance and enables efficient metal machining.In practice, this means that the drill bit can be used to drill holes in sheet metal, structural sections, steel components, and metal structural parts.For the user, this means greater reliability and a lower risk of the tool becoming dull quickly when used properly.

Vertex angle of 135° improves control over the start of drilling.The drill bit “locks onto” the drilling point more easily, which is particularly useful when drilling holes in smooth metal surfaces.This geometry reduces the drill bit's tendency to veer off course, making the product well-suited for tasks requiring precision, such as preparing mounting holes for bolts, metric screws, rivets, or fasteners.

Cylindrical chuck allows the drill bit to be mounted in a standard drill chuck.The drill bit is mounted in a hand drill, a drill/driver with a suitable chuck, or a bench drill.Simply insert the cylindrical shank into the tool holder, center it properly, and tighten the holder jaws securely.This makes the drill bit ready for use on metal during repairs, assembly, the production of small structures, the machining of steel components, and drilling holes in the workshop.

In everyday use, the DEDRA 8.5 mm drill bit set is ideal for drilling holes in metal brackets, assembling steel structures, installing hinges, and repairing gates, wickets, shelving units, handles, clamps, and workshop equipment.It’s also a good choice for installers, mechanics, metalworkers, and anyone who wants to have a reliable set of drill bits with a common working diameter on hand.

Uses for 8.5 x 117 mm HSS drill bits – a reliable set for workshops, assembly, and technical work

Set 5 HSS metal drill bits, 8.5 x 117 mm has been designed for people who value practicality, consistent results, and time savings.The set of five is a big advantage for frequent drilling, as it ensures the user always has spare drill bits on hand without having to interrupt their work.This is particularly important in service facilities, auto repair shops, during structural assembly, and during renovation work, where a single drill bit may be used intensively for an extended period of time.

This product is primarily intended for drilling in metal.It can be used for machining steel components, flat metal bars, profiles, sheet metal, angle iron, and structural parts.Diameter 8.5 mm is useful for preparing technical and mounting holes, such as for screws, cable passages in metal components, workshop fasteners, tool holders, or auxiliary holes in steel structures.

The three most important benefits for the user are drilling accuracy, the long service life of HSS material , and universal compatibility with popular drilling equipment.Precision helps minimize the need for corrections and ensures a clean, neat hole.Durability ensures comfort during extended use, and the cylindrical shank makes it easy to mount the drill bit in many common drills.This makes the DEDRA set a practical choice for both professional use and for demanding DIY enthusiasts.

The drill bit is mounted in the drill chuck from the side of the cylindrical shank.Once properly secured, select the appropriate speed for the type of metal, hold the drill bit firmly against the surface, and begin drilling without applying excessive pressure.When working with harder materials, it is advisable to use cooling or lubrication, which helps reduce heat buildup, improves working comfort, and can extend the drill bit's service life.

The DEDRA 8.5 mm metal drill bit set is a good choice for a garage, toolbox, metalworking shop, technical workshop, manufacturing facility, and repair shop.It is ideal for assembling metal shelving, drilling holes in structural profiles, repairing machinery and equipment, preparing parts for bolting, as well as for hobby projects such as building stands, frames, brackets, or simple steel structures.
