Widin Carbide Drill Single Margin Internal Coolant, 9 mm diameter with an 8xD length, is a high-performance drill bit built from solid carbide for exceptional durability and long tool life. Designed for engineers, machinists, and hobbyists who demand repeatable, accurate holes in demanding metals, it delivers reliable results across steel, stainless, and tough alloys.

The TiAlN coating boosts wear and heat resistance, enabling higher cutting speeds and longer life by reducing wear and dissipating heat more effectively. The single-margin geometry enhances stability and hole straightness, while an internal coolant channel aids chip evacuation and cooling. With its 8xD depth, this drill handles deeper holes with consistent precision.

• Solid carbide construction: Delivers exceptional rigidity and long tool life, resisting wear and deformation for reliable performance in tough metals and demanding drilling applications.
• TiAlN coating for wear and heat resistance: Enables higher cutting Speeds and extended tool life by reducing wear and improving heat dissipation, helping you achieve cleaner holes faster.
• Single-margin design for stability: The single-margin geometry keeps the drill on a true path, reducing wandering and hole deviation, while the internal coolant channel enhances cooling and chip evacuation during deep-hole drilling.

Together, these features translate to fewer tool changes, more consistent hole quality, and greater productivity. The 9 mm diameter and 8xD length give you versatility for a wide range of projects, from precision fabrication to routine maintenance, making this drill a dependable choice for your workshop toolkit.
