SPMG07T308R XP9130

The SPMG07T308R XP9130 is a robust square insert designed for indexable drills (U-drills) requiring high stability. Featuring a 7.94mm inscribed circle and a reinforced 0.8mm radius, this insert is built to withstand the high torque and axial forces found in larger diameter drilling. The XP9130 grade ensures it stays sharp and cool even in difficult-to-machine stainless steels.

Key Features:

• Grade XP9130 (PVD Coated): A "Tough-Grade" specialist. Its PVD coating is designed to stay bonded to the carbide even under the extreme heat of deep-hole drilling. It excels in Stainless Steel (M) and High-Temp Alloys (S).

• 0.8mm Nose Radius: Unlike the standard 0.4mm, the 08 radius provides a much stronger cutting corner. This makes the insert highly resistant to "chipping" during the initial entry into the workpiece and more durable when drilling through uneven surfaces.

• Chipbreaker: The geometry is engineered for maximum chip control. It forces the chips to break into small, manageable pieces that can be easily flushed out by coolant, preventing the "packing" that leads to drill failure.

• Size 07T3 Power: At nearly 4mm thick, this insert provides the mass needed to absorb vibration during high-feed drilling.

Best For:

• Large Diameter Drilling: Fits U-Drill bodies designed for the 07 size insert (typically 24mm to 33mm drills).

• Demanding Materials: Perfect for 304/316 Stainless Steel, Duplex, and Alloy Steels.

• Production Drilling: High-volume CNC environments where reliability is more important than pure speed.
