Seco Tools 14173 5.5mm Pilot 8mm Step Coolant Fed Carbide 2 Flute Twist Drill

Seco Tools 14173 is a carbide, two-flute twist drill with a 5.5 mm pilot and an 8 mm stepped diameter, designed for coolant-fed operation. The carbide construction provides high hardness and wear resistance, while the 2-flute arrangement supports stable drilling and effective chip evacuation in a compact form. The 5.5 mm pilot starts the hole with precision, and the 8 mm step defines the larger diameter as drilling progresses, making it suitable for stepped-hole applications. This tool is part of Seco Tools' line and carries the 14173 part number for identification and compatibility in drilling tasks requiring a coolant-fed carbide twist drill.
