Hey there, if you're tackling some serious masonry work, you'll want a drill bit that can keep up. This Sabre Tools SDS Plus bit is a beast – it's 1-1/8 inches wide and a full 39 inches long, giving you some serious reach for deep holes. It's got a high-quality carbide centric conical tip that starts the hole cleanly and stays sharp. The two-flute design helps pull debris out fast, so you're not fighting a clogged hole and the bit stays cooler. It works with any SDS Plus rotary hammer (think Bosch, DeWalt, Makita, Milwaukee, you name it). Perfect for drilling into concrete, brick, stone, cinder block – you get the idea. It's built tough with an industrial-grade welding process and a hardened steel body. Sabre Tools backs it up with a warranty too (just don't expect a replacement if you wear it out completely or seriously abuse it). If you need to make big, deep holes in tough stuff, this bit is ready for the job.
