Features of the Makita D-21989

• HSS-G (High-Speed Steel Ground) Material: Made from high-quality high-speed steel and subjected to a precise grinding process, this drill bit is strong, highly resistant to heat generated during drilling, and maintains its sharpness better than standard HSS bits.
  
• Razor-Sharp Drill Bit Tip: The precise grinding process results in a very sharp tip, allowing for quick and accurate penetration into materials. This also reduces slippage when starting a hole.
  
• Excellent Chip Evacuation: The precisely designed flutes efficiently clear metal chips from the drilled hole, reducing clogging and ensuring smooth drilling.
  
• Wear-Resistant: Thanks to its high-quality material and manufacturing, the drill bit boasts a long service life, even with heavy use in metal materials.
  
• 1/8-inch (3.175 mm) Size: This is a widely used size for small to medium-sized holes.
  
• Pack of 10 Bits: Offers great value and ensures you always have spare drill bits ready for use.
