Core Drill Bit 4 in Diameter

This 4 in diameter core drill bit is built for contractors and serious DIY users who need to bore precise holes in hard materials. It fits standard equipment with a 5/8"-11 inner thread and reaches a maximum core depth of 9.5 in. The kit includes a pilot bit, adapter, 3.15 in diamond saw blade, and hex wrench for immediate use.

Laser Welded Diamond Segments

Laser welding bonds the diamond segments to the steel barrel for durability in both wet and dry cutting. Dry cutting offers faster speed while wet cutting reduces dust on brick, concrete, and foam brick. The 101.6 mm width and 241.3 mm drilling depth define the practical limits of each pass with this bit.

Simple Assembly With Pilot Guidance

The universal 5/8"-11 thread allows quick mounting on handheld drills without special tools. The included pilot bit centers the bit to prevent walking at the start of the cut. At 4.6 lbs total weight, the assembly is manageable for one operator, though deep holes in dense concrete still demand steady pressure and proper alignment.

Questions about this item

Should I pick the 4 in diameter with 9.5 in depth or look for another size?

This model is a single 4 in diameter bit with a 9.5 in maximum core depth, so there is no alternative version to choose from in this listing.

What does the 9.5 in drilling depth mean when I am on site?

You can extract a core up to 9.5 in deep in one pass, suitable for through-holes in walls, floors or slabs of that thickness.

How does the 5/8"-11 inner thread affect which machines I can use?

The 5/8"-11 thread fits standard core rigs and handheld drills that accept that thread, letting you mount the bit directly without extra adapters.
