The set is designed for users who often need to drill different hole diameters without changing tools — practical for DIYers, repairmen or professionals in the workshop. The non-slip shaft allows for secure clamping in the drill, which reduces the possibility of slipping and facilitates precise work even when drilling holes of different dimensions in succession.\u003c\/p\u003e\u003cp\u003e The drill bits in this set offer great flexibility, as each individual drill bit has a stepped shape that allows you to drill multiple hole diameters with a single bit. This means you will need to change drill bits less often, which speeds up your work, especially when working with materials such as sheet metal, thin profiles or various plastics. The high-speed steel (HSS) design means they are suitable for long-term use without rapid wear or loss of sharpness.\u003c\/p\u003e\u003cp\u003e The compact length of the drills makes it easier to work in confined or difficult-to-reach spaces. Each individual diameter is clearly marked on the drill, which simplifies control of drilling depth and ensures equivalent results in different places. The reduced risk of getting stuck in the material when changing between stages contributes to easier and cleaner drilling without additional hole processing.\u003c\/p\u003e\u003cp\u003e \u003cstrong\u003eKey product features\u003c\/strong\u003e\u003c\/p\u003e\u003ctable class=\"enaa-filter-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003e Property\u003c\/th\u003e\n\u003cth\u003e Value\u003c\/th\u003e\n\u003cth\u003e Rating\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e Type\u003c\/td\u003e\n\u003ctd\u003e Drills\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e Purpose\u003c\/td\u003e\n\u003ctd\u003e Drill bit set\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e Diameter\u003c\/td\u003e\n\u003ctd\u003e Various dimensions (set)\u003c\/td\u003e\n\u003ctd\u003e 🟢 9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e Length (total)\u003c\/td\u003e\n\u003ctd\u003e Up to 100mm\u003c\/td\u003e\n\u003ctd\u003e 🟢 8.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cbr\u003e \u003ca href=\"javascript:compareProducts2('51687240',6172,'shraniVPrimerjavo');\"\u003e⚖️ Compare features with other products of your choice\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e The stepped shape of the drills allows for smooth transitions between individual diameters with minimal effort.
