Carmex Thread Mills Carbide Drill Mill - Metric - M4 x 0.7 - MT7

Meet the Carmex Thread Mills Carbide Drill Mill for metric M4 x 0.7 threads—a precision tool engineered to drill, chamfer, and thread mill in a single, efficient pass. Built for high‑volume production, it delivers consistent thread quality with fewer tool changes.

• Combination operation: drills, chamfers, and thread mills in one pass to cut cycle times and boost throughput.
• Two-fluted geometry: optimized for stable chip evacuation and smooth cutting during threading and drilling.
• 45° chamfer: provides a clean entry and reliable engagement for fast, repeatable threading.
• MT7 shank with Sub‑Micron carbide: high hardness and toughness paired with a durable, wear‑resistant core for long tool life.
• PVD triple coating: enhances cutting efficiency, reduces friction, and extends insert life in challenging materials.
• Internal coolant bore: effective cooling and chip control directly at the cutting edge for better surface finish.
• Right/left hand compatibility: suitable for both right‑hand and left‑hand internal threads, increasing versatility on a single setup.
• Hole versatility: designed for use with both blind and through holes without changing tools.

This thread mill is ideal for precision metalwork where fast, repeatable M4 x 0.7 threads are needed—think automotive components, aerospace fixtures, and electronics housings. The tool’s specialized carbide composition and coating deliver consistent thread quality, smooth surface finish, and dependable performance across repeated cycles, helping you meet tight production schedules without compromising accuracy.
