The Vortex Indexable U-Drill (21 mm) is a versatile, through-coolant drilling solution designed for general-purpose use in steel, stainless steel, cast iron, exotics, and non-ferrous materials. It’s built around the SPMG/SPKX insert system for reliable, easily replaceable cutting edges.

• Inserts compatibility: Uses SPMG or SPKX ISO inserts for flexible, economical tooling.
• Depth capability: 2xD maximum drill depth, suitable for shallow to mid-depth holes.
• Through coolant: Internal through coolant capabilities for improved cooling and chip evacuation.
• System: Indexable U-Drill design with interchangeable inserts for efficient retooling.
• Holder options: Available with 2xD, 3xD and 4xD holders to match depth and rigidity needs.
• Material coverage: General insert grades suitable for Steel, Stainless Steel, Cast Iron and Exotic materials.

Benefits: Achieve precise, consistent holes across a range of metals with an economical, easy-to-maintain indexable solution. Replacing only the inserts reduces downtime and tooling costs, while through-coolant support enhances heat control and surface finish. The 21 mm diameter and 2xD depth design offer a compact, flexible option for standard drilling tasks, and the multiple holder sizes enable you to tailor reach and rigidity to your machine setup and production needs.
