Carmex Carbide Deep Groove Mill With Internal Coolant Bore is a precision solid carbide grooving tool crafted for deep-hole applications. Built for machinists who need long-reach accuracy, it delivers clean, repeatable grooves in depths up to 130 mm.

• Cutting Diameter: 3.5 mm cutting diameter for tight, precise grooves in confined spaces
• Deep-Hole Reach: Designed to groove through holes up to 130 mm deep, enabling long, uninterrupted cuts
• Flute Geometry: 6 spiral flutes that promote efficient material removal and stable, smooth cutting
• Internal Coolant Bore: Direct coolant delivery to the cutting edge improves heat management and chip evacuation
• Material & Construction: Solid carbide construction for high rigidity, wear resistance, and consistent precision
• Minimum Groove Diameter: Requires a minimum groove diameter of 19.5 mm for proper function

This tool excels in creating deep, intricate grooves with controlled chip flow and minimal thermal distortion. The internal coolant bore keeps temperatures down at the cutting edge, extending tool life and reducing the risk of built-up edge. Whether refining grooves in automotive components, molds, dies, or other precision parts, this mill delivers reliable performance, improved surface finish, and reduced rework through superior heat management and chip control.
