The Widin Carbide Drill with Through-Coolant, 8.7 mm diameter, is built for demanding metalworking tasks, delivering long tool life and reliable performance. Its solid carbide core, paired with an AlTiN coating, maximizes hardness and wear resistance while reducing friction for sustained cutting performance. The through-coolant design ensures efficient chip evacuation and effective cooling, helping maintain dimensional accuracy across hole depths up to 3xD.

• Through-Coolant Capability: Directs coolant through the drill to improve chip evacuation and cooling, reducing heat buildup and helping maintain precise hole dimensions.
• AlTiN-Coated Durability: The AlTiN coating provides high hardness and low friction, extending tool life and enabling consistent performance in challenging materials.
• 3xD Length Versatility: The 3xD length offers flexibility for drilling deeper holes while preserving stability and accuracy in every pass.

This combination of carbide hardness, wear-resistant coating, and efficient cooling supports faster cycles, fewer tool changes, and more reliable hole quality—making it a dependable choice for engineers, machinists, and DIY enthusiasts alike.
