Makita D-74728 SDS Plus Drill Bit Set for Concrete

When it comes to construction or installation work involving concrete walls, plaster, or brick, ordinary drill bits often fall short. The Makita D-74728 is a drill bit set specifically engineered to tackle these tough materials.

Features of the MAKITA D-74728

• SDS-Plus Shank System: This is the core of this drill bit set. The SDS-Plus shank features special grooves that securely lock the drill bit into a rotary hammer, ensuring maximum power transfer and impact efficiency. This reduces vibration transmitted back to the user and allows for rapid drilling through hard materials.
  
• Carbide Tip (Tungsten Carbide Tip): Each drill bit boasts a high-quality tungsten carbide tip. This exceptionally hard and wear-resistant material ensures efficient drilling through concrete, brick, or masonry and extends the bit's lifespan.
  
• Excellent Debris Evacuation Flute Design: The drill bit's flutes (grooves) are designed to rapidly and efficiently clear dust and debris from the drilling area. This minimizes dust buildup in the hole and allows for continuous drilling.
  
• High Durability: Built to withstand the high impact and torque from rotary hammer use, these bits are highly resistant to breakage and bending.
  
• Packaging: Comes in a robust, compact, and convenient plastic case for easy storage and transport, keeping the drill bits organized and ready for use.
