Ingersoll Cutting Tools 5120091 Replaceable Drill Tip 0.75in

Product Description

The INGERSOLL CUTTING TOOLS 5120091 is a replaceable carbide drill tip designed for use in modular drilling systems that accept TPA-series insert tooling. This tip is manufactured from solid carbide and coated with TiAlN and TiN via a PVD process, which improves wear resistance and extends tool life in steel and ferrous workpiece applications. It carries a 0.75-inch cutting diameter, a 140-degree included point angle, and a two-flute helical configuration. The grade designation is IN2505, rated for P15 to P30 material groups per ISO classification. Coolant-through capability is built in, making it compatible with through-spindle coolant delivery for chip evacuation and heat management during deep-hole operations.

This tip is suited for production drilling in CNC machining centers and turning centers where modular drill bodies with TPA-series seat size 19 inserts are in use. Primary workpiece material is steel, covering a broad range of carbon, alloy, and structural steel grades within the P15 to P30 ISO range. Typical applications include through drilling, blind drilling, and spot drilling operations in manufacturing environments. The functional length is 0.319 inches with an overall projection of 0.433 inches, fitting the compact geometry of indexable drill systems used at high feed rates.

Key Features

• Solid carbide construction in grade IN2505 for strength and edge stability in steel cutting
• TiAlN and TiN dual coating applied via PVD process for extended wear resistance
• 140-degree point angle reduces entry force and improves centering on flat and curved surfaces
• Two-flute helical design with regular spiral for balanced chip evacuation
• Integrated coolant-through capability for high-pressure coolant delivery directly to the cutting edge
• TPA series, seat size 19 - clamp-style insert holding method for positive retention

Compatibility

Designed for use with TPA-series modular drill bodies that accept seat size 19 replaceable tips. Conforms to ANSI standards and carries ISO number TPA1905R01 IN2505 as referenced in the supplier specification.

Installation Notes

Installation of replaceable drill tips should be performed by a qualified machinist or toolroom technician. Ensure the drill body and tip seat are clean and free of chips or debris before seating the insert, as contamination can cause runout and premature tip failure. Secure the tip using the appropriate clamp key per the tool body manufacturer's torque guidance. Verify coolant port alignment when through-spindle coolant is in use before initiating a cut.
