Diamond Core Drill Bit 3"(76mm) with Pilot Bit & Adapters (SDS Plus & Hex) – Upgraded Welded Segments, 8.6" Depth – for Concrete, Solid Brick, Hollow Brick, Masonry & More

【Diamond Core Bit】：This set comes with everything you need to get started: 1 SDS Plus shank (9.5"), 1 SDS Max shank (9.5"), 1 hex shank (4-5/16"), two pilot drill bits (3/8" x 9.5"), 1 diamond core drill bit, and a dust bag.

【Premium Quality Tungsten Carbide】：Made from tungsten steel and carbide, our hole saws feature high tensile strength. They are extremely hard and offer excellent wear resistance, which is highly valued in cutting tools, drill bits, and abrasives. They are highly corrosion-resistant, even in aggressive environments.

【Versatile Application – Wet or Dry】：Use it wet for concrete, reinforced concrete, and aged or washed concrete. Switch to dry for masonry, brick, sand-lime brick, and screed. With the included adapters, it works with a wide range of powerful hand drills.

【Diamond Cutting Performance】：This hole saw delivers clean, precise cuts even without water, making it a solid choice for low-dust dry drilling in masonry and other hard materials. That said, using water is recommended—it’ll help extend the life of the bit.

【Important – Please Read Before Use】：Do not use hammer drilling mode with this core bit. It's designed for rotary drilling only. To keep things running smoothly, remove the pilot bit after you've drilled through about 5 mm of material, then continue with the core bit on its own.
