AUPEQ | Coated Single End Point Drill PE-90° | YAMAWA

Product Features
● An excellent surface finish can be obtained while maintaining cutting edge sharpness from the high helix flute design.
● Accuracy improvements are also achieved from the single end design.
● A design for higher rigidity enables high speed cutting.
● The problem of cutting edge breakage when the center hole drill is in use has been solved by using the point drill.
● Simultaneous combining the center positioning and chamfering is possible. It can also be used as a multi function tool like groove processing.
● Higher precision machining can be achieved with the two stage point shape design.
● With a single end center point drill, the degree of chip space widens, so the chips are discharged smoothly.
Differences in projection length and degrees of freedom between single end and double end point drills
