The SPZ SDS Plus 4-Cutter Masonry Drill Bit Range is engineered for fast, accurate drilling in concrete, reinforced concrete and masonry. A solid one-piece carbide head with four cutting edges arranged in a 4 × 90° geometry produces precise, round holes while helping prevent the bit from seizing if it encounters reinforcing steel.
A centering point supports accurate starting, while the strengthened flute and high-volume spiral geometry efficiently remove drilling dust and resist torsional forces. Available in 45 size and length combinations, the range covers diameters from 5mm to 32mm and overall lengths from 110mm to 1000mm for anchor installation, through-holes and general construction drilling.
