Fast, clean cutting, thanks to heavy-duty tungsten carbide TCT tip
Tungsten carbide tips resist abrasive wear and retain a sharp edge for longer, while a segmented saw rim ejects debris to help maintain cutting depth. The TCT composition gives a harder contact edge than standard steel.
Cleaner hole edges with less chipping, and longer bit life between replacements. Fewer interruptions on site for resharpening or swapping cutters.
Secure, stable drilling, with 240mm SDS adapter
The 240mm SDS extension bar fits SDS chucks to maintain a positive drive connection and extend reach for deeper or recessed cores. SDS coupling reduces slippage compared with keyed chucks.
Easier access for through-wall or deep penetrations, with steadier rotation and reduced wobble. Less strain on the drill and a more predictable cutline.
Accurate hole placement, with tungsten carbide tipped pilot drill
A dedicated TCT pilot drill centres the core saw and prevents wandering at startup, keeping the cutter aligned. The pilot establishes a true axis before the hole saw engages the material.
Neater, more repeatable holes for vent pipes, drainage and utility penetrations. Reduces the need for corrective chiselling and finishing.
