Feature
1.Products in stock are uncoated, various coatings available according to your needs.
2.Excellent wear resistance and long using life
3.Spotting drills can perform both centering and chamfering. Precise position the holes and chamfer are accomplished at one time to improve the processing efficiency.
4.Workpiece material: Suitable for general steels, alloy steels, tempered steels, casr iron and aluminium alloy, etc.
Notice
1.Fixed-point drilling can only be used for fixed-pointing, dotting, and chamfering, and must not be used for drilling
2.Be sure to test the yaw of the tool before use, please select correction when it exceeds 0.01mm
3.Fixed-point drilling is formed by one-time processing of fixed-point + chamfering. If you want to process a 5mm hole, you generally choose a 6mm fixed-point drill, so that subsequent drilling will not be deflected, and a 0.5mm chamfer can be obtained.
