The Widin 4.5 mm solid carbide drill with AlTiN coating is built for precision metalworking, offering reliable performance and long tool life for engineers, machinists, tradespeople, and hobbyists alike. It delivers clean, consistent holes and steadfast durability in a wide range of materials, making it a dependable choice for everyday drilling tasks.

The 5xD length design enables deeper hole drilling without sacrificing stability or accuracy, reducing the need for tool changes. The AlTiN coating adds a protective layer that boosts wear and heat resistance, lowers friction, and promotes smooth chip evacuation—helping you maintain high productivity even at higher speeds and temperatures.

• Rugged Solid Carbide Core: Provides exceptional rigidity and long tool life for repeatable, accurate hole quality across challenging materials.
• AlTiN Coating for Wear and Heat Resistance: Reduces friction and cutting forces while preserving edge sharpness in high-temperature work, improving efficiency and finish.
• 5xD Long Drill Length: Enables deeper holes with maintained stability and precision, minimizing drift and rework for a smoother workflow.

Together, these features help you complete more work with fewer tool changes, achieve consistent hole geometry, and maintain reliable performance from start to finish. The combination of robust carbide construction and advanced coating supports steady productivity, smoother chip clearance, and confident results across demanding drilling applications.
