Makita D-72849 HSS-TiN Metal Drill Bit Set, 1-10mm (10 Pcs)

This drill bit set is designed to be a reliable assistant for general drilling tasks, especially those involving metal. It combines the key features of high-quality drill bits within a compact package.

Features of the MAKITA D-72849

• Reduced Friction: This ensures smooth drilling and minimizes heat buildup at the drill bit's tip.
  
• Increased Hardness and Wear Resistance: Significantly extends the lifespan of the drill bits compared to standard HSS bits.
  
• High Heat Resistance: Ideal for continuous use or drilling materials that generate high heat, preventing damage to the drill bit.
  
• Precise Drilling Start: The drill bit won't "walk" or slip when starting to drill, eliminating the need for a center punch.
  
• Reduced Drilling Pressure: Helps the drill bit penetrate materials more easily, lessening the load on the user.
  
• Efficient Chip Evacuation: Effectively pushes metal or wood chips out of the drilled hole.
