Ingersoll Cutting Tools 4208148 Replaceable Drill Tip 21mm

Product Description

The INGERSOLL CUTTING TOOLS 4208148 is a replaceable drill tip designed for indexable drill systems used in precision metal-cutting operations. Manufactured from solid carbide and coated with TiAlN and TiN via a PVD coating process, this tip delivers hardness and heat resistance suited to demanding cutting environments. It features a 21.00 mm cutting diameter, a 140-degree drill point angle, and a standard helical flute configuration with two flutes. The tip is rated for the IN2505 grade, targeting stainless steel and similar difficult-to-machine materials. Installation requires a compatible TMA-series drill body with seat size 21.

This replaceable tip is designed for use in drilling and spot drilling applications where coolant-through capability is required. Its primary workpiece material classification is stainless steel, corresponding to ISO material code M, including M15 and M35 subgroups. The tip fits TMA-series indexable drill holders and is well suited for CNC machining centers in both production and job-shop environments. Coolant-through design helps evacuate chips and manage heat at the cutting zone, which is critical when working stainless steel at depth.

Key Features

• Solid carbide construction in manufacturer grade IN2505 for wear resistance in stainless steel
• TiAlN and TiN PVD coating for improved surface hardness and thermal protection
• 140-degree included drill point angle for reduced thrust and accurate entry
• Coolant-through design supports chip evacuation and heat control during deep drilling
• Two helical flutes with regular spiral for consistent chip flow
• Clamp-style insert holding method for secure, repeatable tip seating

Compatibility

Designed for use with TMA-series indexable drill bodies requiring an insert seat size 21. ISO number TMA2100R01 IN2505 identifies the tip geometry and grade for direct cross-reference to compatible holders.

Installation Notes

Replaceable drill tips of this type are installed and serviced by qualified machinists or tooling technicians. Ensure the drill body is fully removed from the spindle and all machine power is off before seating or removing the tip. Use the correct clamping torque as specified by the drill body manufacturer for seat size 21 holders. Verify coolant-through passages are clear and unobstructed before returning the assembly to service.
