Allied Machine 4C10P-16.5 Spade Drill Insert 16.5mm Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 4C10P-16.5 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. It carries a 16.5 mm cutting diameter, a 132-degree point angle, and belongs to the GEN2 T-A series with a Seat Size 0 shank interface. The insert is finished with an AM300 PVD coating, which improves wear resistance and extends tool life in demanding applications. At 0.125 inches thick and 0.1 pounds, it is a compact, precision-ground replacement insert intended for use in compatible T-A spade drill holders. Installation and operation are typically performed by machinists and tooling technicians in CNC or manual drilling setups.

This insert is suited for drilling operations in steel and hard materials across industrial machining environments. The GEN2 T-A platform is commonly used in production shops, job shops, and manufacturing facilities where repeatable hole quality and insert interchangeability are required. The Seat Size 0 designation determines holder compatibility, so verifying the matching holder seat size before installation is essential. Typical applications include through-hole and blind-hole drilling in ferrous workpieces where carbide tooling with PVD coating provides an advantage over uncoated or HSS alternatives.

Key Features

• GEN2 T-A series, Seat Size 0 — fits compatible T-A spade drill holders
• Compact insert dimensions: 1.5 inches wide, 1.5 inches in length, 0.125 inches thick
• Lightweight at 0.1 pounds — single insert per package

Compatibility

Designed for use with GEN2 T-A series spade drill holders accepting a Seat Size 0 insert. Verify holder seat size before ordering to ensure correct fit.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine in a locked-out, zero-energy state per applicable machine safety procedures. Use the correct T-A insert seating tool or torque wrench specified by the holder manufacturer to secure the insert — do not overtighten or use improvised tools that may damage the seat geometry. Inspect the holder seat for wear, chips, or debris before installing a new insert. Follow shop safety protocols and applicable ANSI or ISO machining standards for carbide insert handling.
