How many hole depths can ADF-2D be processed up to
Basically, since the helix angle is weak, the chip discharge is lower than that of conventional drills, so it can be processed in 2D.
How many millimeters is ADF-2D and ADFO-3D possible, from regrinding ? Carbide Flat Drill Series
It can be processed from 3 mm.
Does the ADFO-3D have honing (chanfa)?
It comes with honing (chanfa)
How many millimeters to double margin is ADFO-3D?
φ3 mm or more is a double margin.
Is it possible to process half cracks?
Half-cracking is possible.
What is the pin angle for ADF-2D ADFO-3D?
It will be the pin angle.
Centering of a long shank flat drill
The ADFLS-2D requires a centering hole larger than the drill diameter for surface machining.
Approximate feed amount during ADF-2D plane machining
As a guideline for general materials, set the drill diameter ×2% (drill diameter × 0.02) at the feed amount per revolution (mm/rev).
Measures against internal burrs in the side hole processing of pipes
The ADF-2D and ADFO-3D series are effective for internal burrs in the side hole processing of pipes.
I want to make the tip flat with a hole depth of 5D.
After machining a 5D hole with a normal drill with a tip angle, only the tip angle is machined with ADFLS-2D (a type with a long neck). (The step amount is 0.2D
