The Vortex Indexable U-Drill is a versatile, through-coolant drilling solution designed for general-purpose metalworking. It accepts SPMG or SPKX ISO inserts and is ideal for drilling in steel, stainless steel, cast iron, exotics, and non-ferrous materials.

• Diameter: 21 mm
• Maximum drill depth: 4xD
• Insert compatibility: Uses SPMG or SPKX ISO inserts
• Coolant: Internal through coolant capabilities
• Holder availability: Holders available in 2xD, 3xD and 4xD
• Material suitability: General insert grade available for machining Steel, Stainless Steel, Cast Iron & Exotics

Designed to deliver reliable, efficient drilling across common metals, the U-drill enables productive hole creation with replaceable inserts, reducing tool costs and downtime. The 4xD depth capability allows deeper holes in a single pass, while through-coolant improves chip evacuation and cutting performance on challenging materials. By pairing with ISO-grade inserts (SPMG or SPKX), you can tailor wear resistance to your workpiece and maintain steady productivity when machining steel, stainless steel, cast iron, and exotic alloys.
