What is the guideline for correction of cutting data for slope machining of the ADF series flat drill?

When machining on slopes with a slope of 30° or less of the machining surface, use the feed amount of 40~60% of the cutting condition reference table as a guide.

When machining on a slope

Can the long shank specification of the ADF series of carbide flat drills also be used for deep hole drilling?

As per the model number of ADFLS-2D, the maximum machining depth is up to 2D.

The long shank specification is designed to reach distant processing areas.

If the rigidity of the tool is good, won't the groove be narrower and the chip ejection will be worse?

If the tool is rigid, the thickness will be increased to some extent.

This will reduce the width of the groove ( chip pocket).

However, the stiffness of

Flat drill ADF doesn't twist that strongly, so why does the cutting edge have a good sharpness?

In order to ensure sharpness, it is common to strengthen the twist angle and sharpen the cutting edge.

The ADF series does this with a unique cutting edge shape.

ADF-2D and ADFO-3D backtaper amount  

In order to cope with intermittent cutting, it is stronger at 0.45 ~ 0.50 / 100.
