Allied 152T-0106 Spade Drill Insert 1-3/16 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 152T-0106 is a cobalt spade drill insert designed for high-penetration drilling applications in demanding industrial and manufacturing environments. This insert measures 1-3/16 inches in diameter and features a 132-degree point angle suited for flat-bottom entry and precise hole initiation. Built from T15-grade cobalt high-speed steel and finished with a Physical Vapor Deposition (PVD) TiN coating, the 152T-0106 delivers heat resistance and edge retention across extended production runs. It is part of the T-A Series and fits Seat Size 2 holders. Installation is handled by machinists and tooling technicians working with spade drill body systems.

This insert is engineered for use across a range of primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium. It is a fractional-inch measurement insert, making it compatible with standard inch-based T-A Series spade drill holders used in CNC machining centers, manual drill presses, and lathe setups where interchangeable spade drill tooling is required. Typical applications include through-hole and blind-hole drilling in structural components, tooling plates, and aerospace or heavy industrial parts.

Key Features

• 1-3/16 inch diameter for direct compatibility with Seat Size 2 T-A Series holders
• 132-degree point angle for reduced thrust and clean hole entry
• T15 cobalt high-speed steel construction for elevated hot hardness and wear resistance
• PVD TiN coating reduces friction and extends tool life in ferrous and exotic materials
• Rated for steel, stainless steel, cast iron, superalloys, and titanium workpieces
• Fractional-inch system insert for use in standard imperial-dimension spade drill bodies

Compatibility

Designed for use with T-A Series Seat Size 2 spade drill bodies in fractional-inch configurations. Compatible with primary workpiece materials coded P (steel), M (stainless steel), K (cast iron), and S (superalloys and titanium) per ISO material classification.

Installation Notes

This insert is installed and replaced by machinists or tooling technicians. Power down and lock out the spindle before seating or removing the insert. Use the appropriate torx or hex wrench as specified by the holder manufacturer to secure the insert screw to the correct clamping torque. Inspect the insert seat for chips or debris before installation to ensure proper seating and runout accuracy.
