• Best For: General wet drilling of 4-1/2-inch (114mm) holes through concrete slab, wall and asphalt.
• Highlight: The 114mm 156333 closes the gap between the 4-1/4-inch 156332 and the 5-inch 156334.
• Expert Note: Per inch of depth a 4-1/2-inch core removes about five times the material of a 2-inch core, so plan for more water and a longer cut.
