1.Carbide-tipped tools feature cutting edges of carbide for wear resistance and a steel shank for toughness.
2.Cross-tipped carbide tips which improve durability, accuracy and speed than standard glass and tile bits.
3.Double R Quick change shank reduces slipping in standard chucks and is compatible with all 1/4" quick-change chucks including Japan standard quick change chuck systems.
4.Titanium Coating for high corrosion resistance and low friction.
5.Twist flute design for chip ejection and increase the efficiency of drilling holes.
6.Can not be used on hammer mode, for use with rotary drills only.
7.Best result with lower rpm and good cooling with water, vinegar and turpentine.
