Allied Machine 4C12P-0108 Spade Drill Insert 1-1/4 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 4C12P-0108 is a solid carbide spade drill insert engineered for high-performance drilling in steel and hard materials. Sized at 1-1/4 inches in diameter with a Seat Size 2 designation, this insert belongs to the GEN2 T-A series and features an AM300 PVD coating classified under the C1 (K35) material grade. The 132-degree point angle is optimized for accurate entry and chip control in demanding ferrous and hard-material applications. At 0.1875 inches thick, the insert profile is designed to seat securely in compatible GEN2 T-A spade drill bodies. Machinists and tooling technicians in production and job-shop environments rely on this insert for consistent hole quality and tool life in steel workpieces.

The 4C12P-0108 is intended for use in GEN2 T-A spade drill bodies configured for Seat Size 2. Typical applications include through-hole and blind-hole drilling in carbon steel, alloy steel, and hard materials in manufacturing and machining operations. The AM300 PVD coating provides enhanced wear resistance and thermal stability, making this insert well suited for moderate to high cutting speeds in production drilling environments. It is packaged individually and ordered in single-unit quantities, making it practical for both replacement tooling and new setups.

Key Features

• Solid carbide construction with C1 (K35) material grade for rigidity and wear resistance in steel cutting
• AM300 PVD coating classification provides enhanced thermal and abrasion resistance
• 132-degree point angle optimized for accurate drill entry and chip evacuation in ferrous materials
• GEN2 T-A series insert compatible with Seat Size 2 spade drill bodies
• Fractional inch sizing at 1-1/4 inches diameter suits standard inch-system tooling setups
• 0.1875 inches insert thickness for secure, repeatable seating in the holder

Compatibility

Designed for use with GEN2 T-A series spade drill bodies requiring a Seat Size 2 insert. Primary workpiece material compatibility includes steel (P) and hard materials (H) per the manufacturer grade designations.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine locked out per standard lockout/tagout procedures. Inspect the insert seat in the drill body for wear or debris before seating the new insert, and torque the clamping screw to the drill body manufacturer specification. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.
