Milwaukee 7/8" Carbide Tipped Sheet Metal Hole Cutter 49-57-8309
PRECISION CUTTING PERFORMANCE IN TOUGH ALLOYS
When your jobsite demands clean, burr-free holes in stainless steel or structural studs, standard bi-metal saws often fall short on durability and precision. This carbide-tipped cutter is engineered to bridge the gap between handheld convenience and drill-press accuracy. The specialized carbide geometry is optimized for thin-gauge materials, preventing the grabbing or tearing common with traditional hole saws. By maintaining a sharp edge through high-heat applications, these cutters provide a significantly higher return on investment for professionals working with tough alloys, aluminum, or brass.
- / High-grade carbide tips deliver superior tool life when cutting through stainless steel and structural studs.
- / Optimized 3/16-inch cutting depth prevents over-penetration and ensures clean exits in sheet materials.
- / Precision-ground teeth produce drill-press quality holes even when used with standard handheld drills.
- / Compatible with the 49-57-0035 quick-change arbor for rapid bit swaps and reduced downtime.
