Questions about this item

Should I choose the 8.70 mm diameter or look for a different size?

Select the 8.70 mm drill when your hole must be exactly that diameter; step to the next size up or down if the drawing calls for a different finished hole.

What does the 3X designation mean once the drill is in the machine?

It indicates a flute length roughly three times the 8.70 mm diameter, giving deeper reach in a single pass without pecking.

Which shank standard does this drill use and what does that limit?

A straight cylindrical shank fits standard drill chucks and collets, so the maximum speed and feed are set by the tool holder and workpiece rigidity rather than a proprietary interface.
