Overview
Extended SDS PLUS Adapter 350 mm for Hollow Core Drill Bits with Centre Drill M22 Thread Steel Silver for Drilling into Concrete

The extended clamping adapter, measuring 350 mm, is designed to connect a hollow core drill bit to a rotary hammer with an SDS PLUS chuck. At one end, it features a shank for the hammer, while the other end has a thread onto which the core bit screws. In the middle of the thread, a centre drill is clamped, which holds the core bit precisely in place at the marked spot during use. The extension is intended for drilling holes into concrete, bricks, mixed masonry, and aerated concrete. Thanks to its greater length, the core bit reaches deeper into the wall than with a shorter adapter.

The adapter fits drill bits with an M22 thread, which are available separately in a range of diameters from small holes for cables to large passages. One adapter can be used for various jobs, simply by changing the core bit. The steel body transmits the impacts and rotations of the hammer directly to the cutting teeth of the core bit, keeping it aligned with the hole. The length of 350 mm is practical for drilling perimeter walls, partitions made of solid bricks, or concrete ceilings, where a short adapter is insufficient. The extension also makes it easier to work in areas where you cannot get the hammer very close to the wall, such as behind pipes or in room corners.

Before use, screw the core bit onto the adapter thread until it is tight, and insert the shank into the hammer's chuck until it clicks. Start drilling with light pressure so that the centre drill first creates a guide hole and the core bit does not slip over the surface. Only when the teeth have cut into the material can you apply more pressure. For deep holes, occasionally withdraw the tool and remove the drilled dust and debris. Hold the hammer firmly with both hands and drill perpendicular to the wall, as any deviation will be more pronounced over greater lengths. After finishing work, clean the thread and shank of dust, unscrew the core bit, and store the adapter in a dry place.

The SDS PLUS 350 mm adapter is a useful addition for anyone drilling passages into masonry with hollow core bits. The increased length allows you to complete a passage through a thicker wall without the need for complicated drilling from both sides. The centre drill helps start the hole precisely at the mark and guides the core bit throughout the work. One adapter will serve for core bits of many diameters with the same M22 thread. It can be used for installing drains, ventilation systems, and electrical wiring in family homes as well as on construction sites. It reliably serves during one-off renovations as well as in the daily work of a tradesperson.
