Ingersoll Cutting Tools 4209579 Replaceable Drill Tip 9mm

Product Description

The INGERSOLL CUTTING TOOLS 4209579 is a replaceable drill tip in the TMA series, designed for indexable drilling systems used in metalworking operations. This solid carbide tip measures 9.00 mm in cutting diameter with a 140-degree point angle and a helical, two-flute geometry. It carries a TiAlN/TiN PVD coating applied over an IN2505 grade carbide substrate, which is engineered for hardness and thermal resistance under cutting loads. Coolant-through capability allows fluid delivery directly to the cutting zone, reducing heat buildup and chip evacuation issues during deep-hole drilling. Seat size 9 ensures proper indexing into compatible TMA-style holders.

This tip is suited for drilling and spot drilling applications in stainless steel and other difficult-to-machine materials classified under ISO material group M. It is appropriate for use in CNC machining centers, turning centers with live tooling, and drill presses in both production shop and job-shop environments. The IN2505 grade and M15/M35 material grade designations indicate suitability for austenitic and duplex stainless steels where edge toughness and coating adhesion matter. The coolant-through design makes this tip especially practical for deeper cut-to-diameter ratios where chip packing is a concern.

Key Features

• 9.00 mm cutting diameter with 140-degree standard point angle for accurate entry and reduced thrust force
• Solid carbide construction in grade IN2505 for wear resistance in stainless and tough alloy steels
• TiAlN/TiN PVD coating improves heat resistance and extends tool life in M-group workpiece materials
• Coolant-through design delivers fluid directly to the cutting edge for chip control and thermal management
• Two-flute helical geometry promotes efficient chip evacuation in blind and through-hole applications
• Clamp-style insert holding in seat size 9 provides rigid, repeatable tip seating in TMA-series holders

Compatibility

Designed for use with TMA-series indexable drill holders accepting seat size 9 replaceable tips. ISO number TMA0900R01 IN2505 identifies the exact holder and seat pairing required for correct fitment.

Installation Notes

Installation and tip changes should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine power isolated. Use the correct torx or clamp key specified by the holder manufacturer to seat the tip to the recommended clamping torque noted in the holder documentation. Inspect the seat pocket for chips or debris before indexing a new tip, as contamination under the tip can cause premature fracture or runout issues. Verify coolant port alignment with the holder coolant passages before resuming cutting operations.
