Our 5.1mm diameter HSS drill bit is made of durable high performance cut steel with profile-ground quality and is ideally suited for drilling holes in substructures and panels that are to be fastened with our facade rivets. Profile-ground means that both the flute and the cutting edge of the drill bit are precision-ground on the outer diameter and the drill tip. Thanks to the cross-grinding of the drill tip, the HSS-G drill already cuts in the middle of the drill head. A further advantage of the grinding is that the drill is self-centring, which means that precise drilling can be carried out with little effort.
The twist drill made of high speed steel has a normal spiral twist (type N) with a cross-grinding and a point angle of 118 degrees. The total length of the drill is 86mm, of which 52mm is the spiral length and 34mm is the cylindrical shank, which also has a diameter of 5.1mm.
The twist drill is a profile-ground drill, which is characterised by a longer service life and better sharpness than the cheaper, roll-rolled HSS-R drills. This enables precise drilling, even on hard materials such as steel or cast steel, without the drill suffering from wear and tear too quickly.
Scope of delivery:

For the assembly of facade cladding on an aluminium substructure, we have a wide range of facade rivets in different lengths and colours in our online shop, with a hollow rivet diameter of 5mm. Matching to this we also offer inexpensive aluminium profiles for the substructure of flat claddings, which are suitable for both bonding and riveting. While it is not necessary to drill holes into the substructure when bonding with an assembly adhesive, holes with a diameter of 5.1mm must be drilled for the facade rivets. With our HSS-G drill for facade rivets, we offer you a suitable drill for drilling metal substructures.
In addition, the drill is also very suitable for fixed point drilling in aluminium composite panels, which is very important for safe and accurate positioning of the cladding panel. However, for any necessary sliding point drilling of a panel, you should use a drill with a size of at least 8mm (maximum 10mm), as this is the only way to ensure sufficient clearance for thermal expansion.
With a diameter of 5.1mm, our profile-ground HSS drill is also ideal for drilling holes in panels that are to be screwed directly onto the wall. All conventional screws with a maximum thread diameter of 5mm are suitable for this, regardless of whether the screw is screwed into the masonry with a dowel or whether a wood screw is used that is to be screwed directly into the wood. Screwed connections in the visible area can be evaluated optically with our stainless steel screw head covers.
The drill is also suitable for all riveted joints with a sleeve diameter of 5mm, where holes should always be drilled 0.1mm - 0.2mm larger. You are not limited to drilling holes in our plastic sheets, but can also drill holes in steel, aluminium or many other metals in order to rivet them later. Furthermore, the drill can be used to drill holes for screw connections with M5 screws, for example for the production of metal housings. The 5.1mm drill can also be used to drill metal substructures where assembly is to be carried out with our balcony screws. A good example of this is balcony railings made of steel, which are to be clad with our HPL panels.
WARNING: When drilling with the HSS drill, make sure that you deactivate the percussion drilling function of your drill, as this can considerably shorten the life of the drill.
