Seco Tools SD504-2000-800-1500R7 Indexable Insert Drill

Seco Tools Perfomax SD504 indexable insert drill, model SD504-2000-800-1500R7, delivers precise holemaking with a 2.000-inch cutting diameter and a maximum drilling depth of 4xD. The SD504 family uses square inserts with four cutting edges and a robust drill tip geometry designed for high wear resistance, enabling reliable holes with no pilot drilling required and strong edge life. This R7 variant employs a 1-flat mounting interface for secure centering and compatibility with Seco toolholding, aligning with Seco’s pre-tensioned drill body design that retains clamping forces across the tool life to extend insert life and maintain steady performance. The line emphasizes a single geometry for all materials, good chip evacuation, and straight-hole quality even when drilling to depths up to 4D, making it a production-friendly choice for deep-hole work on suitable ferrous and nonferrous metals. Diameter range for SD504 tooling spans 0.594–2.375 inches, with 4XD as the standard depth option for the series, and the SD504-2000-800-1500R7 variant targets applications requiring reliable 2.0-inch holes in demanding machining environments.
