Part of the OSG's "A brand" line-up, the ADF carbide flat drills are general purpose drill bits excellent for general purpose drilling, in particular for stainless steel. Under the "One drill does it all", the ADF is perfect for pre-drill holes for tapping. 

OSG propietary coatings (IchAda, EgiAs) provide high abrasion resistance and heat resistance enable small diameter tools to achieve long tool life. Also, superior geometrical design allow for a much more higher number of unclogged drilling operations and a much higher precision repeatability, also improving the tapping process by impeding the formations of exit burs.
