Description
The Widin Carbide Drill Through Coolant 7.7 mm is a high‑performance drill built from solid carbide for exceptional durability and long tool life. It’s designed for professionals across engineering, manufacturing, and hobbyist projects who require reliable drilling results.
Equipped with through coolant capability and a 3xD flute length, this drill manages heat and evacuates chips efficiently, helping maintain dimensional accuracy and extend tool life even in demanding materials and deeper holes.
- Solid carbide construction: Delivers high durability and long tool life, ensuring consistent and reliable performance across heavy‑duty drilling tasks.
- AlTiN coating for wear resistance: The coating provides excellent wear resistance, high hardness, and low friction, translating into reduced wear, longer life, and higher productivity.
- Through coolant with 3xD length versatility: Through coolant supports efficient chip evacuation and cooling, minimizing heat build‑up and preserving tool life; the 3xD length enables drilling a wide range of hole depths while staying stable and precise.
This combination of durable carbide, wear‑resistant coating, effective cooling, and versatile length helps you complete jobs faster with fewer tool changes, maintain tight tolerances, and achieve reliable hole quality across a variety of materials and applications.
