With its tri-margin design and self-stabilizing point, the Hi-PerCarb Series 131N drill for aluminum has continuously proven to outperform the competition in measured hole quality at a variety of speeds and feed rates.
Features
TRI-MARGIN DESIGN
Improved hole stability over two-flute designs
Superior surface finish, roundness, and hole cylindricity
Unsurpassed hole size control
SELF-STABILIZING POINT & OPEN FLUTE STRUCTURE
Pyramid design stabilizes the drill on contact with the workpiece
Efficiently transports chips while maintaining strength at high feed rate
SCULPTED GASH
Allows chips to easily flow away from the drill center
Reduced cutting forces over competitive three-flute designs
High wear resistance, reduced friction, and excellent prevention of cutting edge build up. This coating allows superior material removal rates and tool life when used in high performance operations in Cast Iron and Steel and with difficult to machine materials like Titanium.
