Allied Machine 1C20A-14 Spade Drill Insert 14mm Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C20A-14 is a solid carbide spade drill insert designed for high-penetration drilling in demanding industrial and metalworking applications. This insert measures 14 mm in diameter with a 132-degree point angle and a Seat Size 0 configuration. It carries a TiAlN (Titanium Aluminum Nitride) PVD coating and meets the C2 (K20) manufacturer grade standard. The T-A series design delivers consistent chip evacuation and hole quality in production drilling environments. Installation is performed by machinists and toolroom professionals working with compatible T-A series spade drill bodies.

This insert is engineered for use across a range of workpiece materials including stainless steel, cast iron, non-ferrous metals, and super-alloys and titanium. It fits T-A series spade drill holders sized for Seat Size 0 tooling. Typical applications include component manufacturing in aerospace, heavy equipment, and general machining environments where precise hole geometry and tool longevity in difficult-to-machine materials are required.

Key Features

• 14 mm cutting diameter with 132-degree point angle for aggressive entry geometry
• Solid carbide substrate at C2 (K20) grade for hardness and wear resistance
• TiAlN PVD coating extends tool life in high-heat and abrasive cutting conditions
• Seat Size 0 T-A series interface for repeatable insert indexing and seating
• Rated for stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium
• 0.125 inch insert thickness for dimensional consistency across the T-A seat system

Compatibility

Designed for use with ALLIED MACHINE AND ENGINEERING T-A series spade drill bodies configured for Seat Size 0 inserts. Suitable for workpiece materials classified under ISO material groups M (stainless steel), K (cast iron), N (non-ferrous), and S (super-alloys and titanium).

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the drill body and seat are clean and free of chips or debris before seating the insert. Use the manufacturer-specified insert screw and a calibrated torque driver to secure the insert without over-torquing the seat screw. Always power down and lock out the spindle before changing or indexing any insert.
