Ds Overall length L Point length ℓ1 JIS POINT DRILLS Spiral Fluted Taps (for blind hole) ① Product Features Spiral Fluted Taps (for through hole) ●The improved design enables better rigidity for high speed cutting. ② ●A stronger helical flute design helps improve workpiece surface The drill point angle is 125° , The chamfer angle is finishes while maintaining good cutting edge sharpness. available as a 90° or 60° . Simultaneous centering and chamfering with one tool! Chamfering and groove Spiral Pointed Taps (for through hole) processing are also possible! ③ ●Unlike a normal center hole drill, there is no drill part with a Point Drill, so the problems with breakage of the drill portion is eliminated. ●Simultaneous combining the positioning and chamfering are possible. It can also be used as a multi- Hand Taps ④ function tool for groove machining. ●High precision machining can be achieved with the two stage point shape.
