Milwaukee 3/16" RED HELIX Cobalt Drill Bit 5-Pack 48-89-2359

EXTREME ALLOY PENETRATION PERFORMANCE

When your crew is burning through standard consumables on high-tensile stainless or structural steel, the ROI on your tooling takes a massive hit. The Milwaukee 48-89-2359 5-Piece Pro Pack is the mechanical solution for high-heat, high-stress drilling environments where standard black oxide bits fail. Engineered with a specialized Cobalt alloy and the proprietary RED HELIX™ geometry, these bits are designed to maintain edge integrity and prevent thermal breakdown during continuous heavy-duty cycles in the toughest ferrous metals.

• / QUAD EDGE TIP™: Engineered to slice through hard metals with significantly less heat friction, keeping the cutting edge sharper for 15X longer than standard tooling.
• / VARIABLE HELIX™ GEOMETRY: Features an aggressive 35° helix angle transitioning to 15° for rapid chip evacuation, preventing material weld-back and overheating.
• / ENHANCED TAPERED WEB™: A reinforced internal core significantly boosts the bit's structural integrity, minimizing flute snapping under high-torque drilling loads.
• / 135° SPLIT POINT: Prevents bit walking on smooth or curved surfaces, delivering an immediate precision start without the need for a center punch.
• / 3-FLAT SECURE-GRIP™ SHANK: Eliminates bit slippage within the chuck, ensuring 100% of the drill's torque is transferred directly to the work surface.
