The Vortex Indexable U-Drill is a general-purpose drilling solution designed for reliable through‑hole production. Sized at 28 mm, it uses ISO SPMG or SPKX inserts for easy, cost-effective tool changes.

• Diameter: 28 mm
• Maximum drill depth: 3xD
• Insert compatibility: Uses SPMG or SPKX ISO inserts
• Coolant: Internal through coolant capability
• Holder availability: 2xD, 3xD and 4xD holders
• Material compatibility: General insert grades for Steel, Stainless Steel, Cast Iron & Exotics

This U‑drill delivers efficient, repeatable hole-making across common engineering materials. The through‑coolant design helps manage heat and chip evacuation for longer tool life and steadier performance, while the standard SPMG/SPKX inserts keep costs predictable and replacement straightforward. With a 3xD depth limit, it’s well-suited to mid‑length hole drilling, and the 28 mm diameter hits a versatile mid‑range size ideal for general manufacturing and production environments.
