Ingersoll Cutting Tools 4208146 Replaceable Drill Tip

Product Description

The INGERSOLL CUTTING TOOLS 4208146 is a replaceable drill tip designed for indexable drilling systems used in metal-cutting operations. Built from solid carbide and coated with TiAlN and TiN via a PVD process, this insert delivers wear resistance and heat management during high-feed drilling of steel workpieces. It features a 1.0157 inch cutting diameter, a 140-degree point angle, and a helical flute design with 2 flutes. The coolant-through design channels fluid directly to the cutting edge, helping control chip evacuation and thermal buildup. This tip is installed by machinists and toolroom technicians working with compatible TPA-series drill bodies.

This replaceable tip is suited for production drilling, spot drilling, and coolant-through drilling applications in ferrous materials, primarily steel in the P15 to P30 material grade range. It conforms to ANSI standards and is classified under UNSPSC code 23242105. Typical environments include CNC machining centers and turning centers where indexable drill systems are used to reduce downtime associated with regrinding solid drills. Insert seat size is 25, matching the corresponding TPA-series drill body seat.

Key Features

• Solid carbide construction for rigidity and edge retention in steel cutting
• TiAlN and TiN PVD coating for enhanced wear and oxidation resistance
• 140-degree standard point angle reduces entry forces and centering drift
• Coolant-through design improves chip evacuation and controls cutting zone temperature
• 2-flute helical geometry with regular spiral for balanced chip flow
• Clamp-style insert holding for secure seating and repeatable positioning

Compatibility

Designed for use with TPA-series indexable drill bodies requiring an insert seat size of 25. ISO designation is TPA2580R01 IN2505.

Installation Notes

Installation and replacement should be performed by qualified machinists or toolroom personnel with the machine fully stopped and in a safe, locked-out state. Use the appropriate torx or hex key specified for the TPA-series clamp system when seating the insert. Inspect the seat pocket for debris or damage before installing a new tip, as contamination can affect runout and tip seating. Verify coolant-through channels are clear and unobstructed before resuming operation.
