Applications
for Seco Tools
Seco Tools offers carbide drills ideal for manufacturers in the automotive, aerospace, and medical industries. These applications often require precision holemaking in challenging materials, including difficult-to-machine alloys, deep holes, and micro-diameters.
Such environments demand stable hole quality in mass production—but issues like heat concentration, tool wear, and chip clogging in deep holes can compromise both tool life and machining accuracy.
Seco’s solid carbide drills address these challenges through:
- High tool rigidity and wear resistance, to reduce thermal deformation and chipping
- Optimized flute geometries and through-coolant designs, to ensure efficient chip evacuation—even in deep-hole applications
Note: Performance may vary depending on cutting conditions, coolant type, spindle speed, feed rate, and machine rigidity.
