Allied Machine 434T-0130 Spade Drill Insert 1-15/16 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 434T-0130 is a high speed steel spade drill insert designed for high-penetration drilling applications in metalworking and machining operations. Built to Seat Size 4 specifications within the GEN2 T-A series, this insert features a 132-degree point angle and a TiN (Titanium Nitride) PVD coating applied over an M4 material grade HSS substrate. The TiN coating reduces friction, extends cutting edge life, and improves heat resistance during extended drilling cycles. At 1-15/16 inches in diameter and 0.3125 inches in thickness, the 434T-0130 is suited for production drilling where consistent hole quality and insert longevity are priorities. Licensed machinists and tool-and-die professionals are the primary installers of this insert type.

The 434T-0130 is used in spade drill holder bodies that accept Seat Size 4 inserts within the ALLIED MACHINE AND ENGINEERING GEN2 T-A system. Typical applications include production drilling through steel, cast iron, and non-ferrous metals in CNC machining centers, drill presses, and lathes. The 132-degree point angle suits through-hole and blind-hole drilling in ferrous and non-ferrous workpiece materials. It is well suited for shops running high-volume hole-making operations where insert-style tooling reduces downtime compared to solid drill replacements.

Compatibility

Designed for use with ALLIED MACHINE AND ENGINEERING GEN2 T-A series spade drill holder bodies that accept Seat Size 4 inserts. Primary workpiece material compatibility includes steel (P), cast iron (K), and non-ferrous metals (N) per ISO material classification codes.

Installation Notes

Installation of spade drill inserts should be performed by a qualified machinist with the machine fully powered down and the spindle locked before insert removal or installation. Seat surfaces on the holder body should be inspected and cleaned of chips and debris before seating the new insert. Follow the tooling manufacturer torque specifications for the insert clamping screw as specified in the GEN2 T-A system documentation. Proper insert seating and clamping is critical to hole accuracy and insert life.
