Allied Machine Revolution Drill

Product system overview

Revolution Drill is Allied Machine's adjustable large-diameter indexable drilling system for drilling from solid or opening an existing hole. It is designed to maintain penetration on lower-horsepower machines and uses multiple inserts, replaceable cartridges, through coolant, and diameter adjustment to reduce the number of dedicated bodies required.

Industries and applications

• Large-diameter holes on machines with limited available horsepower.
• Drilling from solid without a pilot or opening an existing hole while accommodating limited core shift.
• Stacked-plate applications and work performed on either lathes or mills.

Published technical profile

• Can drill from solid without a pilot or open an existing hole.
• Allied states that the system can ignore core shifts up to 3.175 mm (0.125 in) in applicable opening operations.
• Published diameter adjustment is up to 5.1 mm (0.200 in) on diameter.
• Uses replaceable and adjustable cartridges, multiple inserts, through coolant, and available integral shanks.
• Insert choices include Allied AM200 and AM300 coatings plus high-rake and general-purpose geometries.

Selection notes

Use Revolution Drill when large-hole flexibility and low-horsepower capability justify an adjustable multi-insert system.

Document cartridge positions, insert grades, final measured diameter, runout, coolant, and machine-specific cutting data.

Variables to validate

• Cartridge setup and diameter adjustment require controlled assembly and measurement procedures.
• Large-diameter drilling still depends on spindle power, torque, rigidity, coolant volume, workholding, and entry or exit conditions.
• Opening an existing hole and drilling from solid impose different centerline, insert-loading, and chip-evacuation conditions.
