DMI Diamond Core Bit Sharpening Block

Our Professional Grade Core Drill Bits are made in the USA with high-quality materials built to last. Diamond core drill bits are made to withstand intense drilling against concrete. However, after extensive use, they sometimes can dull out. That’s why we made a sharpening block for your drill bits. Instead of having to just buy a new one, you can sharpen the ones you already have. After sharpening your diamond drill bits with this block, you’ll be able to drill through concrete at a much faster rate. Size:12” x 12”
