• Diameter range:

• Diameter range:

• Diameter range:

5.800 mm - 32.100 mm. • Available with central or radial through coolant. • Can be used for through or blind holes. • Cylindrical shanks improve concentricity. • Expandable to accommodate for wear.

9.600 mm - 80.600 mm. • Heads are available as fixed or expanding for improved producƟvity. • Straight, leŌ-hand, or right-hand helical flutes provide soluƟons for both through and blind holes. • Cylindrical or modular shanks improve concentricity.

17.600 mm - 200.600 mm. • The cuƫng edges are posiƟoned asymmetrically to assure the best roundness of the hole. • Holes with Ɵght tolerances can be accommodated, and the expansion ensures a perfect holding of the reaming diameter.

General Reaming Notes • If the depth is over 9xD, use a short length reamer to pilot the hole. Then finish with the longer length . • For blind-hole applicaƟons, always use central coolant. If in doubt, contact Allied’s ApplicaƟon Engineering department. • More stock allowance can be taken in soŌer materials. Less stock allowance should be taken in harder materials. • A common pracƟce is to rapid out of the cut on through holes and to breakout only 2 mm past the reaming depth.

IMPORTANT: Always use Molykote® (anƟ-seize applicant) on the conical seat and the threads on the central screw for assembly.

NOTE: The posiƟon of the dimples indicates which two cuƫng teeth are 180° opposed. Diameter measurements should be taken from these two cuƫng teeth.

Tool failure can cause serious injury. To prevent: - When using holders without support bushing, use a shorter reamer to establish an iniƟal hole that is a minimum of 2 diameters deep. - Do not rotate tool holders more than 50 RPM unless it is engaged with the workpiece or fixture. Factory technical assistance is available for your specific applicaƟons through our ApplicaƟon Engineering department : appeng@alliedmachine.com. WARNING
