Ingersoll Cutting Tools 4209903 Replaceable Drill Tip 0.5315in

Product Description

The INGERSOLL CUTTING TOOLS 4209903 is a replaceable drill tip designed for use in modular indexable drill systems. It measures 0.5315 inches (17/32 inch) in cutting diameter and features a 140-degree included point angle suited for fast, accurate hole entry. The tip is manufactured from solid carbide at a submicron grain grade, coated with TiAlN and TiN via a PVD process for extended tool life in abrasive materials. Coolant-through capability channels cutting fluid directly to the cutting edge, managing heat and chip evacuation during deep-hole operations. Machinists and tool and die professionals install this tip on compatible TKA-series drill bodies in CNC machining centers.

This drill tip is engineered primarily for cast iron workpieces, consistent with its K-material-group designation. It suits production drilling applications in automotive, heavy equipment, and general machining environments where high cutting speeds and coolant delivery are standard. The helical flute geometry and regular spiral type support efficient chip removal during through-hole and spot-drilling operations. Insert seat size 13.5 and clamp-style holding match TKA-series tool body seats. Applications listed in the product data include coolant-through drilling and spot drilling.

Key Features

• Solid carbide submicron-grade construction for wear resistance in cast iron and similar K-group materials
• TiAlN and TiN PVD coating for thermal protection and extended edge life
• 140-degree point angle reduces entry thrust and supports accurate hole location
• Coolant-through design delivers fluid directly to the cutting zone for heat and chip management
• Helical flute with regular spiral type promotes consistent chip evacuation
• Clamp-style insert holding in a size 13.5 seat for positive, repeatable location

Compatibility

Designed for use with TKA-series indexable drill bodies that accept insert seat size 13.5 with clamp-style holding. ISO number for this tip is TKA1350R01 IN2505. Verify seat size and clamping style against the drill body specification before ordering.

Installation Notes

A licensed machinist or toolroom technician should install and replace indexable drill tips in accordance with the drill body manufacturer's torque and seating procedures. Power down and lock out the spindle before handling any indexable insert. Ensure the insert seat and clamp are free of chips and debris before seating the tip, as contamination affects runout and edge life. Confirm coolant-through passages in the tool body are clear and aligned before resuming operation.
