This Bosch PRO SDS plus-5X is a 28mm diameter, 450mm length masonry drill bit, combining a large bore with extended reach for deep, heavy-duty drilling in reinforced concrete. Supplied as a single bit. Where a 28mm hole needs to penetrate through thicker concrete or multiple layers, the 450mm length provides the depth required without needing specialist extensions on site. Features and Benefits: • Lasts up to 1.5x longer than a Bosch SDS plus-1 Drill Bit. • 4-cutter head resists jamming and breakage on rebar. • 4-flute design reduces dust and ensures smooth performance. • High-quality tungsten carbide for strength and durability. • Fits all SDS plus rotary hammers.
