• 
  Three Different Sizes: The package contains three conical drill sizes 4-12mm, 4-20mm, 4-32mm, with different sizes to meet different drilling needs, universal standard 6.3mm hex diameter, compatible with a wide range of models of drills, can be used for aluminium, wood, thin iron, PVC material, plastic plates.



• 
  Reliable Material: Made of high-quality steel with titanium coating to increase surface hardness and improve the sharpness and durability of the drill, reducing friction and excessive heat during use, and the double helix design prevents slipping and helps to penetrate the chip during work. The 118o design on the top allows drilling from multiple angles.



• 
  Precise Cutting: Each conical drill is equipped with a laser marking for precise selection, the sharp drill cuts more precisely into the material without abrasion, ensures optimal hole spacing, and with increasing hole diameter, the speed is reduced to ensure safe cutting



• 
  Double Spiral Shape: The double spiral design ensures smoother drilling and effectively avoids resistance or stagnation during use, it can be used for drilling or tearing and has faster speed and precision to ensure clarity when drilling or rubbing. Improve work efficiency



• 
  Easy To Use: To effectively extend the life of the drill and avoid softening or discolouration, the drill needs to be moved with water or cutting fluid to keep it at a low temperature when working. Please clean the surface in time after use to avoid corrosion from other substances.
