Ingersoll Cutting Tools 5101254 Replaceable Drill Tip 21mm

Product Description

The INGERSOLL CUTTING TOOLS 5101254 is a replaceable drill tip designed for indexable drilling applications in steel and similar ferrous workpiece materials. Built to the TPA series standard and identified by ISO number TPA2140R01 IN2505, this solid carbide tip features a 21.00 mm cutting diameter and a 140-degree drill point angle suited for accurate entry and reduced thrust in structural and machined-component work. The tip carries a PVD-applied TiAlN/TiN dual coating for heat resistance and extended tool life. Coolant-through capability is integrated, directing fluid directly to the cutting edge for chip evacuation and thermal control. Installation follows a clamp-style insert holding method compatible with the TPA seat size 21 interface.

This replaceable tip is intended for use in metal cutting operations on steel workpieces, covering material grades P15 through P30 per ISO classification. Typical applications include through-drilling, spot drilling, and coolant-assisted drilling on CNC machining centers and turning centers equipped with TPA-series drill bodies. The helical flute geometry with regular spiral promotes consistent chip flow, making it appropriate for production drilling in ferrous materials where tool change frequency and insert cost per hole are key considerations. It conforms to ANSI standards and carries UNSPSC code 23242105.

Key Features

• 21.00 mm cutting diameter with a 140-degree standard point angle for accurate hole entry
• Solid carbide construction in manufacturer grade IN2505 for rigidity and wear resistance
• PVD-applied TiAlN/TiN coating for elevated temperature resistance and extended edge life
• Coolant-through design directs fluid to the cutting zone for chip evacuation and thermal management
• 2-flute helical geometry with regular spiral supports stable chip flow in steel
• Clamp-style insert holding with TPA seat size 21 interface for repeatable tip positioning

Compatibility

Designed as an OEM-style replaceable tip for TPA-series indexable drill bodies accepting insert seat size 21. Compatible with primary workpiece materials classified under ISO P-code (steel), grades P15 to P30.

Installation Notes

Replaceable drill tips of this type are installed and serviced by machinists or toolroom technicians on CNC machining centers. Power down and lock out the spindle before removing or seating the tip. Use the manufacturer-recommended torque wrench and clamp screw to secure the tip in the seat - do not overtighten by hand or use improvised tools, as improper clamping force affects tip seating and runout. Verify coolant-through passages are clear and aligned before resuming operation.
