A Brand products (A-Drills, A-Taps and A-End Mills) are designed to exceed the evolving manufacturing needs of our customers. The A-Drill series features EXOCARB^® AD, ADO, ADO-SUS and ADF. Experience the level of quality, reliability and satisfaction that can only be delivered by OSG’s A Brand tooling master class!

EXOCARB^® AD & ADO 2D-30D

The EXOCARB^® AD & ADO feature superior point strength with low cutting force are achieved to accommodate a wide range of carbide drilling applications. EgiAs coating constructed with extreme toughness, high wear and heat resistance characteristics ensure stable and consistent tool life. The EXOCARB^® ADO offers a coolant-through option for those with coolant capabilities.

AD & ADO Features

• EgiAs Coating for exceptional wear resistance and toughness
• Coolant-Through (ADO) for longer tool life and smooth chip evaluation
• Optimized Drill Geometry For Every Drilling Depth
  • Wavy Point Form (2D-8D) reduces thrust and torque while creating smaller more manageable chips
  • Straight Point Form (10D-30D) enhances cutting edge strength while reducing cutting forces
  • Wide Flutes (2D-8D) facilitates stable chip evacuation
  • Middle Margin (8D-30D) improves stability in deep-hole applications

EXOCARB^® ADO-SUS 3D & 5D

Work hardening, welding, elongation of cutting chips and poor thermal conductivity are common problems in the machining of stainless steels and titanium alloys. The ADO-SUS is a carbide drill series that employs a unique coolant hole shape and tool geometry to enable efficient drilling in these difficult-to-machine materials.

ADO-SUS Features

• Patented "MEGA COOLER" Coolant Holes drastically increase coolant flow, suppressing heat generation and enhancing chip evacuation
• Patented Flute Geometry forms ideal chips for efficient chip evacuation
• Patented Cutting-Edge Geometry reduces work hardening
• WXL Coating provides superior heat and wear resistance for long tool life

ADO-SUS Line-Up

• List 5200 – 3D
• List 5210 – 5D

EXOCARB^® ADF 2D

Machining a flat hole traditionally required the use of an end mill and a drill. The EXOCARB^® ADF enables one-step drilling to simplify machining time and tool management. Suitable for a wide variety of drilling applications including inclined surfaces, curved surfaces, counterboring, eccentric holes, thin plates, etc.

ADF Features

• EgiAs Coating for exceptional wear resistance and long tool life
• Wide Flutes for superior chip evacuation
• Balanced Point Form for reduced thrust and improved stability
• Improved Cutting Edge reduces cutting forces and creates smaller chips

ADF Line-Up

• List 5700 – 2D
