Allied Machine 4TEX

Product system overview

4TEX is an Allied Machine indexable insert drill designed to increase penetration rates while using lower drilling forces. The system uses a reusable coolant-through body and four-edge indexable inserts selected by material and application condition.

Industries and applications

• Production drilling where indexable-edge economics and lower drilling force are priorities.
• Machines that benefit from distributing cutting load across center and peripheral insert positions.
• Applications where insert geometry and grade can be tuned without replacing the drill body.

Published technical profile

• Architecture: indexable drill body with replaceable multi-edge carbide inserts.
• Allied positions the system around higher penetration with lower drilling forces.
• Coolant delivery, body length, diameter, shank, insert position, geometry, and grade vary by catalog item.
• 4TEX has its own insert geometry directory and should not be quoted using Revolution or Opening Drill inserts.
• Complete assembly selection requires both the drill body and all position-specific insert designations.

Selection notes

Use 4TEX where indexable drilling economics, reduced cutting forces, and body reuse fit the machine and tolerance requirement.

Compare the complete edge cost, power requirement, hole quality, and chip evacuation against replaceable-head alternatives.

Variables to validate

• Center and peripheral insert positions may use different wear patterns and must be monitored separately.
• Indexable drills generally produce different hole quality and diameter behavior than exchangeable-head or solid-carbide systems.
• Exact dimensional coverage and depth ratios must be checked against the current Allied catalog.
