Feedmax™ -P Goes Above and Beyond Typical Hole Drilling Technology

Manufacturers typically look to universal drills to help reduce the need to maintain large, diverse tools stocks. However, a one-size-fits-all solution often cannot provide the tool life or cutting speeds of tools optimized for a given application or material. To meet the needs of manufacturers for whom performance and tool life are the most critical factors, Seco developed the Feedmax™ -P, which incorporates geometric features optimized for superior surface finishes and the highest productivity in iron and steel.

Designed to run at extreme speeds and feeds, the Feedmax™ -P has large tapered flutes and straight cutting edges to ensure greater strength and efficient heat dissipation. The precise location of the through-tool coolant holes and the larger flutes quickly and efficiently evacuate chips, and the need for pecking is eliminated when the machine maintains appropriate coolant pressure. For this drill design, Seco engineers placed the through-tool coolant holes as close as possible to the ideal position on the cutting edge.

With narrow land margins, the Feedmax™ -P reduces friction and diminishes the wear of the connection between land margin and corner chamfer to promote better chip formation and decreases heat generation. This geometric feature also minimizes the risk of chipping, which gives the drill a more predictable tool life and higher application security.

To further improve the performance of the Feedmax™ -P, Seco Tools utilized a special double-layer TiAIN (titanium aluminum nitride) coating to increase the drill’s oxidation resistance. A thick bottom layer promotes heat dissipation while the top layer helps prevent built-up edge. In addition to proper heat dissipation and good edge retention, this double-coating process promotes excellent adhesion and eliminates flaking to promote long tool life.

Thanks to its advanced TiAIN coating and strong point geometry, the Feedmax™ -P makes cutting speeds of 623 feet/min possible in SMG P5 without sacrificing tool life. But to reap the full benefits of the Feedmax™ -P’s advanced holemaking technologies, shops must set up the drill properly and run at the correct speeds and feeds. When they do, the performance of the Feedmax™ -P amazes most users. More impressive still, those basic parameter values are actually relatively conservative based on the actual performance capability of the drills. By following the recommendations, manufacturers can achieve highly effective chip evacuation and enjoy the full value of their tool investment.
