Precision-Grade CNC Grooving & Parting Inserts for Lathe Operations

Ultra-fine H12/15 Comma Small Hole Design ensures superior chip control and reduced vibration during high-speed machining. Carbide substrate with advanced TiAlN coating extends tool life by 3X compared to standard inserts.

MB-05GR/07GR/09GR series compatibility makes it ideal for thin-wall machining, precision boring, and micro-grooving applications. Mirror-polished rake face minimizes friction for aluminum/copper alloys.

Industrial-grade tungsten steel construction withstands 1200°C continuous cutting temperatures. Specifically engineered for Swiss-type lathes and CNC automatic screw machines.

Exclusive internal coolant channel design (0.3mm micro-holes) enables flawless dry/wet cutting in aerospace titanium parts and medical device components.

Full geometry compliance with ISO 13399 standards. Includes pre-coated anti-rust film for overseas shipping protection. Minimum order quantity applies for bulk pricing.
