Milwaukee 1-3/8" One-Piece Carbide Hole Cutter

MAXIMUM DURABILITY STAINLESS STEEL DRILLING

For the professional managing high-volume mechanical installations or metal fabrication, the Milwaukee 49-57-8623 represents a significant upgrade in consumable ROI. Engineered specifically for the abrasive nature of stainless steel and hardened alloys, this one-piece carbide cutter eliminates the vibration and instability common in modular hole saw setups. By integrating the arbor and cutter into a singular, rigid chassis, Milwaukee ensures that rotational energy is focused entirely on material removal, providing a cleaner finish and significantly longer tool life compared to standard bi-metal alternatives.

• / High-Grade Carbide Teeth: Optimized geometry provides superior heat resistance and maintains edge sharpness through repetitive cuts in hard metals.
• / Precision Stop Shoulder: Built-in depth gauge prevents over-drilling and limits the cut to 3/16-inch, protecting internal components or wiring behind the workpiece.
• / Spring-Loaded Plug Ejection: Automatically clears the metal slug upon completion, eliminating the manual prying and downtime that slows down high-production workflows.
• / 3-Flat Shank Design: Ensures a secure, non-slip interface with 1/2-inch drill/driver chucks, preventing rotational failure under high-torque applications.
