MDF Flat drills
The flat MultiDrill MDF type is a solid carbide drill that can be used for various purposes including high-efficiency spot facing and drilling in inclined and curved surfaces. It can be used in a variety of drilling applications thanks to its point angle of 180° so that it is applicable to high-efficiency spot facing, drilling in non-horizontal surfaces such as inclined and cylindrical surfaces and interrupted drilling. It also reduces burrs at hole exits by more than half compared to general-purpose drills.
MDF type achieves high rigidity by employing RS THINNING, which ensures web thickness on the bottom face. Obtains excellent chip evacuation thanks to its wide chip pocket and high-quality rake face shape. Additionally MDF type achieves excellent cutting edge strength thanks to optimized cutting edge design.

Features
• Effective for inclined and curved surface spot drilling
• Reduced burrs at hole exits
• Applicable for interrupted and cross drilling
  • MDF Series - Coated Carbide Drills for Spot Facing
