Practical tips for best results

• Pair with a capable SDS-Max rotary hammer for maximum impact energy and stable bit retention.
• Start with a light touch to establish the hole, then increase feed pressure as the bit finds its center in the masonry.
• Keep the drill steady and allow the flute to clear debris; pause briefly if the bit slows to prevent overheating.
• Tip: use a drilling fluid or light mist where appropriate to manage dust and heat during long holes in dense concrete.

Whether you’re installing heavy anchors, running conduit, or setting structural fasteners, the Bosch SpeedX SDS-max Masonry Drill Bit combines reliable steel construction, a precise 7/8" bore, and an extended reach to get the job done efficiently.
