1.Hexagonal shank: shank machined with 6 flats
2.Excellent hold of the bit inside the chuck, enables maximum torque transmission.3.High-temperature soldering: diamond grains are welded at a high temperature for better adherence to the crown.
4.The resistance of the grains increases the life of the tool, and also enables the drilling of very strong materials.
5.Dry drilling: enables drilling without lubricant.
6."Dry" work, with neither water nor oil, clean and safe environment.
