Stop fussing over receptacles or generators in the shop when squaring and facing tube. Tri Tool’s new STS-4 cordless benchtop tube squaring machine features a sleek black finish and an upgraded metal chip guard that resists scratching, improving visibility and durability. Key features include quick-change, tool-free saddles, graduated feed, and a high-visibility design that includes our new Lumen light, which provides illumination to easily see scribe lines on a workpiece. The new STS-4 comes with a dual-range variable-speed brushless drive, perfect for cleanroom applications. The cutting head supports squaring, facing, beveling, and ID deburring bits, making it a trusted solution across industries for larger tube cutting and squaring tasks. The new STS-4 is also available as a corded version.
