STAR-M Auger Impact Bit Drill Medium Type No.7M

SUMMARY

For drilling slightly deeper through holes with an impact driver.

All sizes are 6.35 mm hexagonal shafts compatible with impact drivers.
By making the tip screw and marking blade smaller than conventional drills, the cutting resistance when using an impact driver is suppressed and the battery life is increased by 20%.
The tip of the drill is a screw type.
Using the rotational force of the tip screw, smooth drilling is possible without pressing.
The size 26mm or larger is a double-edged, double-claw type that takes cutting resistance into account.
Available in short, middle and long types depending on the drilling depth.
