High-Speed Masonry Core Drill - Ideal for SDS Plus Machines
Experience rapid, precise, and effortless drilling with our High-Speed Masonry Core Drill, engineered for use ideally with SDS Plus machines. Designed specifically for brick, block, and masonry drilling, this lightweight 2.5 mm ultra-thin wall core drill delivers speeds up to 35% faster than conventional designs—while dramatically reducing breakthrough and vibration.
Manufactured with ultra-hard tungsten carbide cutting tips, this professional-grade masonry core drill bit ensures exceptional wear resistance and enables operation in both rotary and hammer-action modes for maximum drilling speed and efficiency.
Perfect for plumbing and electrical installations, the High-Speed Masonry Core Drill produces clean, accurate holes through concrete, brick, and blockwork with minimal effort. The ball-locking pilot drill system, an original innovation, removes the need for grub screws—allowing quick, secure interchange of pilots and arbors on site.
The precision-machined arbor flats and Tommy Bar hole make core removal and assembly separation effortless, ensuring a smooth workflow and extended tool life.
Ideal for professionals seeking high-performance core drilling equipment made for speed, accuracy, and durability on every job.

Tech-Tip
When cleanliness of breakout is critical, turn off hammer action and use 'rotary only' mode for the last part of the drilling process
Recommended Speed
Recommended speed for these cores is largely governed by the power tool itself. This is because they are designed to be used in power tools where in the majority of cases there is no facility to regulate the speed (SDS Plus, SDS Max machines etc.).
If used in a machine where speed regulation is possible, a general recommendation is the larger diameter of the core drill being used, the slower the speed.
