Widin Carbide Drill Single Margin Internal Coolant 8XD TiAlN Coated - 7mm is a precision drill designed for metalworking tasks that demand reliability, stability, and deep-hole capability. With a solid carbide body, TiAlN coating, and an internal coolant channel, it delivers long tool life and consistent cutting performance across a range of metals and alloys.

Designed for professionals and serious hobbyists alike, this 7 mm diameter drill features a single-margin geometry that provides excellent stability and straight-hole quality. The 8xD length enables deeper hole drilling while maintaining rigidity, and the internal coolant helps control heat and evacuate chips for cleaner finishes.

• Solid carbide construction: Delivers exceptional durability and a long tool life, maintaining accurate hole size and consistent performance even under demanding speeds and feeds.
• TiAlN coating for wear and heat resistance: Enables higher cutting speeds with improved wear resistance, extending tool life when drilling hard alloys and high-temperature materials.
• Internal coolant and 8xD depth capability: Constant coolant flow and effective chip evacuation keep temperatures down and allow accurate, deep-hole drilling up to 8xD with cleaner finishes.

This drill helps you shorten cycle times and reduce tool changes by delivering reliable depth control, stable hole geometry, and consistent results across a variety of machining applications—from precision fixture work to automotive and general fabrication. It’s a dependable choice for anyone who values predictable performance, reduced downtime, and professional-quality holes.
