Building on Carmex’s MT threading tools, the MTB line introduces through-bore coolant to simplify chip evacuation and extend tool life. This solid carbide thread mill with an MT7 shank is designed for precise metric threading (MJ 12 x 1.75) in demanding workpieces.

• Through-bore coolant: coolant flows directly through the bore to carry chips out of the hole and keep the cutting zone cool for smoother, more reliable threading.
• Solid carbide construction: rigid, wear-resistant material that maintains accuracy during high-speed, high-precision threading applications.
• MT7 shank: compatible Morse Taper 7 mounting for secure, robust tool seating in suitable machines.
• Metric thread geometry: MJ 12 x 1.75 — 12 mm nominal diameter with a 1.75 mm pitch for precise metric threads.
• Optimized for threading operations: engineered to deliver consistent thread forms with efficient chip control and reduced rework in challenging materials.

By enabling coolant to reach the cutting edges and leveraging the durability of solid carbide, this thread mill delivers reliable performance across extended machining sessions. It’s ideal for environments where precise metric threads are required in metal parts, enabling cleaner holes, steadier feeds, and longer tool life with less downtime for tool changes.
