Ingersoll Cutting Tools 3204255 Replaceable-tip Drill

Product Description

The INGERSOLL CUTTING TOOLS 3204255 is a replaceable-tip drill body designed for precision hole-making in metal cutting operations. Built on the TD series platform, this drill body accepts TKA, TMA, TNA, TPA, TPC, and TPF insert styles at Insert Seat Size 25, allowing tool-room flexibility without swapping out the entire holder. The shank diameter measures 1.25 inches with a Weldon Flat profile for positive drive and reduced pullout risk. Through-coolant capability delivers cutting fluid directly to the cutting zone, extending insert life and improving chip evacuation in deep-hole applications. Licensed machinists and tooling technicians are the primary installers of this style of modular drill body.

This drill body covers a diameter range of 0.9843 to 1.0197 inches with a maximum drill depth of 2.95 inches, corresponding to a 3xD depth-to-diameter ratio. It is suited for production drilling on CNC machining centers and horizontal boring mills in both job-shop and high-volume manufacturing environments. The right-hand cutting direction and PVD-compatible design make it a reliable choice for ferrous and non-ferrous metal applications where repeatable hole location and finish are required.

Key Features

• Diameter range of 0.9843 to 1.0197 inches covers common bore sizes without a dedicated solid drill
• 3xD depth-to-diameter ratio with 2.95 inches maximum drill depth
• Weldon Flat shank (1.25 inches diameter) provides positive drive and resists rotational pullout
• Through-coolant design channels fluid directly to the cutting edge for chip clearance and heat control
• Compatible with TKA, TMA, TNA, TPA, TPC, and TPF insert styles at Insert Seat Size 25
• Right-hand cut, TD series toolholder style with PVD coating classification

Compatibility

Designed for use with TKA, TMA, TNA, TPA, TPC, and TPF replaceable-tip inserts at Insert Seat Size 25 in the TD series toolholder system.

Installation Notes

Installation and insert changes should be performed by a qualified machinist or tooling technician with the machine powered down and all axes at rest. Confirm the Weldon Flat setscrew in the spindle or toolholder is properly torqued per the machine manufacturer's specification before operation. Verify through-coolant ports are clear and that the machine's coolant-through spindle supply is active before initiating the cut. Always inspect the insert seat for chips or debris before seating a new insert tip.
