Allied Machine 4C12P-0105-HE Spade Drill Insert 1-5/32 in

Product Description

The ALLIED MACHINE AND ENGINEERING 4C12P-0105-HE is a solid carbide spade drill insert designed for high-efficiency hole-making in steel and hard materials. Part of the GEN2 T-A series, this insert features a 132-degree point angle and an AM300 PVD coating applied over a C1 (K35) carbide grade substrate. The AM300 coating improves wear resistance and extends tool life in demanding cutting applications. At 0.1875 inches thick and weighing 0.06 pounds, the insert is engineered to seat precisely in a Size 2 T-A spade drill holder. Machining professionals and tooling technicians specify this insert for production drilling operations where consistent hole quality and insert longevity are priorities.

This insert is suited for drilling operations in steel and hard material workpieces in both production shop and job-shop environments. The GEN2 T-A platform is commonly used in CNC machining centers and manual lathes running high-volume hole-making cycles. The Size 2 seat designation matches specific T-A spade drill bodies in the ALLIED MACHINE AND ENGINEERING GEN2 T-A system. It is appropriate for applications where a replaceable carbide insert is preferred over a brazed-tip or indexable alternative, allowing quick changeover without removing the holder from the spindle.

Key Features

• 1-5/32 inch diameter solid carbide insert for precision bore sizing
• 132-degree point angle optimized for entry geometry in steel and hard materials
• AM300 PVD coating for improved wear resistance and extended tool life
• C1 (K35) carbide grade substrate suited for primary workpiece materials coded P and H
• Seat Size 2 design for direct replacement in compatible GEN2 T-A spade drill bodies
• 0.1875 inch insert thickness for consistent seating and rigidity

Compatibility

Designed for use with ALLIED MACHINE AND ENGINEERING GEN2 T-A series spade drill holders accepting a Size 2 seat insert. Specific holder compatibility should be confirmed against the GEN2 T-A product line documentation prior to ordering.

Installation Notes

Insert replacement should be performed by a qualified machining technician with the spindle fully stopped and the machine in a locked-out, energy-isolated state per applicable safety procedures. Use the correct torque wrench and insert-seating tools specified for the T-A holder system to avoid seat damage or improper clamping. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Do not operate the tool if the insert is not fully seated or if the clamping screw shows signs of damage.
