The SDS MAX adapter for core drill heads 450mm offers a cost-effective and extremely practical solution to this problem. Instead of buying expensive, specialized and extremely long core drills, you simply and quickly extend your existing core drill head with an M22 thread.\u003cbr\u003e Thanks to the included pilot drill bit, starting drilling is extremely easy and safe. The pilot drill bit first reliably makes a pilot hole, which then holds the entire heavy core bit and long adapter assembly in a perfectly straight line. When the core bit cuts into the material, the pilot drill bit ensures that the entire drilling operation is smooth, stable and without unnecessary, dangerous vibrations that could damage your power tool or the material.\u003cbr\u003e\u003cbr\u003e Demonstration video of how it works in practice\u003cbr\u003e See how easy, fast and efficient it is to work with our professional core bit adapter.
