Ingersoll Cutting Tools 5120186 Replaceable Drill Tip 18mm

Product Description

The INGERSOLL CUTTING TOOLS 5120186 is a replaceable drill tip designed for indexable drilling systems where the cutting head is swapped independently of the drill body. Built from solid carbide in manufacturer grade IN2505, this tip carries a dual PVD coating of TiAlN and TiN applied to extend wear resistance and reduce heat buildup at the cutting edge. The 18.00mm cutting diameter and 140-degree drill point angle suit through-hole and spot drilling operations in demanding materials. Coolant-through capability channels fluid directly to the cutting zone, supporting tool life and chip evacuation in production environments. Machinists and toolroom technicians working with CNC machining centers are the primary installers.

This tip is engineered for stainless steel applications corresponding to material grades M15 and M35, where work hardening and heat generation at the cut are primary concerns. The TMA series design with helical fluting and regular spiral geometry promotes controlled chip flow out of the flute. Coolant-through drilling, spot drilling, and standard through-hole drilling are all listed applications. The clamp-style insert holding method seats the tip securely in a compatible TMA-series drill body. The ISO number TMA1850R01 IN2505 identifies the exact tip geometry and grade combination for ordering and replacement purposes.

Key Features

• Solid carbide construction in grade IN2505 for hardness and thermal stability
• Dual PVD coating: TiAlN and TiN for oxidation resistance and surface hardness
• 140-degree drill point angle optimized for stainless steel entry and centering
• Coolant-through design delivers cutting fluid directly to the tool tip
• 2-flute helical geometry with regular spiral for efficient chip evacuation
• Clamp-held replaceable tip reduces downtime versus brazed or solid drill replacement

Compatibility

Compatible with TMA-series indexable drill bodies accepting an 18mm insert seat size. ISO designation TMA1850R01 IN2505 identifies the precise body and tip pairing. Designed for stainless steel workpiece materials classified under M15 and M35 material grades per ANSI standards.

Installation Notes

Installation is performed by machining professionals following the drill body manufacturer torque and clamping procedures for the TMA insert seat. Ensure the spindle is fully stopped and machine is locked out before seating or removing the tip. Inspect the insert pocket for debris or damage before clamping the new tip; a contaminated seat can cause tip runout and premature failure. Coolant-through ports should be verified clear before resuming operation.
