Allied Machine 1C22A-0111 Spade Drill Insert 1-11/32 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C22A-0111 is a solid carbide spade drill insert designed for high-performance hole-making in demanding materials. Part of the T-A series, this insert measures 1-11/32 inches in diameter and seats in a Size 2 holder. It features a 132-degree point angle and a TiAlN (Titanium Aluminum Nitride) PVD coating applied over a C2 (K20) carbide grade substrate. The coating improves heat resistance and tool life when cutting abrasive or hard workpiece materials. This insert is installed by machinists and tool-and-die professionals in CNC drilling operations where consistent bore quality and extended insert life are required.

The 1C22A-0111 is suited for drilling stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. These are materials that demand a tough, heat-resistant cutting edge. Typical applications include production drilling on CNC machining centers and lathes in aerospace, automotive, and general metalworking environments. The T-A series spade drill system uses a two-component design — a replaceable insert mounted to a reusable holder — which reduces tooling cost per hole compared to solid-shank alternatives.

Key Features

• 1-11/32 inch diameter with Seat Size 2 for use with compatible T-A series holders
• Solid carbide construction, manufacturer grade C2 (K20) for wear resistance in hard and abrasive materials
• TiAlN PVD coating improves thermal stability and reduces built-up edge in stainless steel and super-alloys
• 132-degree point angle suitable for flat-bottom entry and general-purpose drilling geometry
• 0.1875 inch insert thickness for positive seating and repeatable positioning in the holder
• Rated for primary workpiece materials including stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium

Compatibility

Designed for use with T-A series Seat Size 2 spade drill holders. Compatible primary workpiece material codes are M (stainless steel), K (cast iron), N (non-ferrous metals), and S (super-alloys and titanium).

Installation Notes

Spade drill insert replacement is performed by a machinist or tooling technician with the machine fully powered down and the spindle locked. The insert seats into the holder using the manufacturer-specified clamping screw — inspect the seat pocket for chips or debris before seating the new insert to ensure proper registration. Follow the holder manufacturer torque guidelines for the clamping screw; over-tightening or under-tightening the screw can cause insert movement or damage to the seat. Confirm insert orientation and point geometry are correct before returning the tool to service.
