• Best For: General wet drilling of 1-3/8-inch (35mm) holes in concrete and asphalt where a standard grade bit is enough for the job.
• Highlight: Standard grade MK Yellow construction delivers fast drilling and good footage for everyday wet coring at an entry level price point within the MK range.
• Expert Note: Sized at 1-3/8 inches (35mm), this bit is for small holes only; it is a wet-drilling bit, so run it with a water supply on your core drill.
