Allied Machine 11831183 Indexable Insert Drill 4xd

Product Description

The ALLIED MACHINE AND ENGINEERING 11831183 is a solid carbide indexable insert drill from the EC 04 series, designed for precision drilling and boring operations in machine shop and production environments. The tool features a straight shank with flat, a 4xD drill depth-to-diameter ratio, and an axial concentric coolant entry system that delivers coolant directly through the body to the cutting zone. With an overall length of 1.614 inches and a flute length of 0.630 inches, this drill is built for consistent, repeatable performance in tight-tolerance applications. It is installed and operated by machinists and CNC tooling technicians.

This drill is suited for general-purpose drilling and boring in ferrous and non-ferrous materials where a compact, solid carbide body is preferred. The EC 04 series targets small-diameter work, with a maximum drill diameter of 4.00 mm and a shank diameter of 6.00 mm. The right-hand cutting direction and straight-with-flat shank make it compatible with standard collet and toolholder setups on CNC machining centers and drill presses. Coolant-through capability supports chip evacuation and extended tool life in deeper cut applications within the 0.630-inch maximum drill depth range.

Key Features

• Solid carbide tool body for rigidity and wear resistance in precision drilling
• Coolant-through design with axial concentric entry for direct cutting zone cooling
• 4xD depth-to-diameter ratio supports deeper drilling without tool deflection
• Straight shank with flat for secure toolholder engagement and reduced slip
• Right-hand cutting direction compatible with standard CNC spindle rotation
• EC 04 series insert compatibility with solid carbide inserts

Compatibility

Designed as an OEM-style replacement and direct-fit drill body for EC 04 series solid carbide insert systems. Accepts solid carbide inserts compatible with the EC 04 series designation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or toolholder bore matches the 6.00 mm shank diameter before clamping. Confirm coolant-through lines are clear and properly pressurized before initiating the first cut.
