The twist drill DIN 338 HSS-G in 10.0 mm diameter with cross-grinding is characterised by long tool life, even when drilling hard materials such as steel, cast steel, aluminium and many other metals, and is also suitable for plastics with high surface hardness.
✓ Very long service life
✓ Profile-ground quality
✓ Self-centering tip
✓ Made in Germany
✓ 87mm spiral length
✓ Tip angle 118°
The 10mm HSS-G drill is ideal for larger sliding point drillings or for our 15mm diameter spacers.

Our HSS drills with a diameter of 10.0mm are ideal for our stainless steel wall spacers or for drilling sliding points in plastic panels that are to be used as facade cladding or balcony edging. Due to the large diameter, even in the case of strong heat development of the panel surfaces, a bulging of the panels after installation can be effectively counteracted. The drills are precision-ground drills in which a greater sharpness is achieved by grinding the drill spiral and the drill tip. Due to the cross-grinding of the drill head, it already cuts centrally on the drill tip. This gives the drill self-centring properties, which enables more precise drilling. We do not only offer our high-quality drills at a very reasonable price from one drill on, but also with attractive quantity discounts, so that you can buy even cheaper when buying several drills. The discount is deducted automatically from our shop system.
Der Bohrschaft hat eine Länge von 46 mm und hat eine zylindrische Form mit einem Durchmesser von 10,0 mm. Die Gesamtlänge des Bohrers beträgt 133 mm und die Länge der effektiv nutzbaren Bohrerwendel 87 mm. Als Spiralbohrer des Typs N hat der Bohrer eine normale Spiralspirale.
HSS-G drills, in contrast to the cheaper HSS-R drills, are milled from one piece and not roll-rolled. In addition, HSS-G drills are sharpened after the cutting edge and the drill head. The advantages compared to roll-rolled drills are a higher sharpness of the drill and a longer service life due to longer tool life. Therefore, our ground drills made of high-speed steel are perfectly suited for drilling hard materials such as steel, alloyed and unalloyed cast steel, iron or even our aluminium composite plates. Also for drilling hard, brittle plastics such as acrylic glass, a profile-ground drill achieves significantly better results.
TIP: Blunt or damaged drills should be discarded, because damaged drill tips or drill spirals can contribute to the drilling not being sufficiently precise.
While the smaller 8mm drill is too small for mounting wall signs with our 15x15mm spacer, the 10mm drill is the perfect size for drilling holes in the panels where the high quality stainless steel brackets are to be used for wall mounting. Even with our spacers with a diameter of 13mm, the cover cap is still large enough to completely cover drill holes with 10mm. With our spacer in 10x15mm, however, this drill cannot be used any more, because the small wall holder can be pushed through a 10mm hole completely and therefore has no hold. The 10mm drill is also not suitable for the very robust wall bracket in 25x25mm, because larger holes between 12mm and 16mm are necessary.
For cladding of facades and balconies with plastic panels that have a high coefficient of thermal expansion, the drill with a diameter of 10mm is also more suitable than a drill in 8mm. However, this only applies to fixing points which, as sliding points, are intended to ensure the necessary room for expansion. Fixed points must always be drilled with drills whose diameter matches the mounting material used. For our balcony screws with M5 thread or our facade screws with a thread diameter of 5.5mm, a drill with a diameter of 6mm should be used. For fixed points with our head lacquered facade rivets, the HSS drill bit with 5.1mm is the right choice.
As metal drills, HSS drills are usually used for drilling metals such as steel, aluminium or iron. Thanks to the better sharpness of a twist drill in profile-ground design, it is also possible to drill holes in plastics with excellent quality. Due to the thickness of the drill bit, a low speed should always be observed to prevent the drill bit from becoming too hot and annealing in hard materials such as cast steel or grey cast iron. With a cooling lubricant or special drilling paste, excessive heat development can be effectively avoided, which has a positive effect on the already very long service life. With plastics, you should always work at reduced speed. However, this is not due to premature wear, but should prevent the drill from heating up too much and the drill chip from fusing with the drill or the edge of the drill hole.
WARNING: In order not to damage the drill, care should be taken to ensure that percussion drills are set to drill without impact.
