Milwaukee SDS Plus 4-Cutter MX4 Drill Bit 1/2" x 4" x 6" 10-Pack 48-20-7971

ELIMINATE REBAR LOCK-UP DOWNTIME

When your crew is setting hundreds of drop-in anchors daily, the true cost of a bit isn't the sticker price—it's the catastrophic failure when hitting hard aggregate or rebar. The Milwaukee MX4™ 4-Cutter series is engineered for high-volume fleet reliability, utilizing a solid head carbide design that doesn't just survive rebar hits; it dominates them. By integrating variable flute geometry, these bits clear dust with mechanical efficiency, keeping the head cool and ensuring your M18 FUEL rotary hammers deliver maximum holes-per-charge ROI.

• / SOLID HEAD CARBIDE: Provides up to 5X longer life in reinforced concrete compared to standard 2-cutter bits.
• / REBAR GUARDS: Engineered geometry specifically designed to prevent the bit from binding or snapping upon impact with steel.
• / VARIABLE FLUTE DESIGN: Optimizes dust extraction to reduce friction and heat, increasing cordless tool runtime by up to 20%.
• / SHARP CENTERING TIP: Enables precise placement on metal decking or smooth concrete, preventing bit walk before the hole starts.
• / WEAR MARK INDICATOR: Visual cue ensures every hole drilled still meets ANSI B212.15 tolerances for critical anchor integrity.
