Ingersoll Cutting Tools 4208142 Replaceable Drill Tip 1 in

Product Description

The INGERSOLL CUTTING TOOLS 4208142 is a replaceable carbide drill tip designed for indexable drilling systems using the TPA series platform. The tip measures 1.0000 inches in cutting diameter with a 140-degree included point angle and a helical, 2-flute geometry. It is manufactured from solid carbide in grade IN2505, a PVD-coated carbide grade with TiAlN and TiN finish suited for steel cutting applications in the P15 to P30 material range. Internal coolant-through channels support chip evacuation and thermal management during deep or high-feed drilling cycles. Machinists and CNC operators in production machining environments install this tip as the cutting end of a modular drill body.

This tip is intended for use in steel and steel alloys classified under ISO material group P, covering general structural steels, carbon steels, and alloyed steels in the P15 to P30 hardness range. It fits insert seat size 25 TPA-series modular drill holders and is suited for both through-hole drilling and spot drilling operations. The coolant-through design makes it well-matched for applications requiring consistent chip flushing, such as deep-hole drilling on CNC machining centers or turning centers with live tooling. It conforms to ANSI standards and carries the ISO designation TPA2540R01 IN2505.

Key Features

• Solid carbide construction in grade IN2505 for wear resistance in steel cutting
• TiAlN and TiN PVD coating for thermal protection and extended tool life
• 140-degree point angle reduces thrust force and improves self-centering
• 2-flute helical geometry with coolant-through capability for chip evacuation
• Fits TPA-series seat size 25 modular drill bodies
• Functional length of 0.4190 inches, overall projection of 0.5710 inches

Compatibility

Designed for use with TPA-series indexable drill bodies accepting insert seat size 25. ISO designation TPA2540R01 IN2505 confirms fitment. Verify seat size and series designation on the drill body before ordering.

Installation Notes

Installation is performed by a machinist or tooling technician. The machine spindle must be fully stopped and the tool holder secured before seating or removing the tip. Use the appropriate torx or clamp key specified by the drill body manufacturer to achieve proper clamping force - do not overtighten or use improvised tools. Confirm tip seating and runout with a dial indicator before resuming cutting operations.
