Allied Machine 182T-33 Spade Drill Insert 33mm Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 182T-33 is a cobalt spade drill insert designed for use in T-A series spade drill bodies. It produces a 33 mm diameter bore and features a 132-degree point angle suited for consistent chip formation and accurate hole entry. The insert is coated with titanium nitride (TiN) via a PVD process, which improves surface hardness and extends cutting life across a range of ferrous and hard-to-machine workpiece materials. At 0.1875 inches thick, it seats in a Size 2 holder and delivers rigid, repeatable performance in production drilling applications. Machinists and tooling specialists in job shops, manufacturing facilities, and production machining environments are the primary users.

This insert is appropriate for drilling operations on steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It fits T-A series spade drill bodies using a Size 2 seat and is built for both horizontal and vertical machining centers as well as manual lathes and drill presses where spade tooling is specified. The 132-degree point angle makes it well-suited for flat-bottomed or shallow-entry applications where a sharper point geometry helps control thrust and positioning.

Key Features

• 33 mm cutting diameter with a 132-degree point angle for accurate hole entry
• Cobalt insert material provides elevated heat resistance compared to standard HSS
• TiN coating applied via PVD process for improved wear resistance and tool life
• Size 2 seat fits standard T-A series spade drill bodies
• Rated for steel, stainless steel, cast iron, super-alloys, titanium, and hard materials
• 0.1875 inch insert thickness for rigid seating and dimensional consistency

Compatibility

Designed for use with T-A series spade drill bodies requiring a Size 2 seat insert.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and manufacturer-recommended fasteners when seating the insert to ensure proper clamping without deforming the pocket. Inspect the insert seat for chips or debris before installation, as contamination can cause insert rocking and premature failure. Follow the toolholder manufacturer's setup documentation for correct insert orientation and retention screw torque sequence.
