Description

Its single-margin geometry and internal coolant channel help keep the drill steady and the cutting edge cool, translating into more precise holes with fewer deviations—even when drilling deep into tougher materials.

Solid carbide construction: Delivers exceptional durability and long tool life, maintaining accuracy through repeated use and drilling a variety of tough materials.
TiAlN coating for wear and heat resistance: Significantly reduces edge wear and allows higher cutting speeds, boosting productivity and extending tool life across metals like steel and cast iron.
Internal coolant with 8×D reach: Built-in coolant channel directs cooling fluid to the cutting edge and aids chip evacuation, supporting stable, straight holes in deep drilling applications up to 8×D.

With these features, the Widin carbide drill helps you complete deeper holes with confidence, reducing downtime from overheating or chip buildup while delivering consistent hole size and finish. The robust carbide core and TiAlN coating help maintain sharpness longer, while internal cooling keeps temperatures in check for reliable performance from first hole to last.
