BORING

• Diameter range: 5.80 mm - 32.10 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

• Diameter range: 17.60 mm - 200.60 mm • The cutting edges are positioned asymmetrically to assure the best roundness of the hole • Holes with tight tolerances can be accommodated, and the expansion ensures a perfect holding of the reaming diameter

• Diameter range: 11.80 mm - 60.60 mm • Heads are available as fixed or expanding for improved productivity • Straight, left-hand, or right-hand helical flutes provide solutions for both through and blind holes • Cylindrical or modular shanks improve concentricity

REAMING

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 applications, always use central coolant. If in doubt, contact Allied’s Application Engineering department. • More stock allowance can be taken in softer materials. Less stock allowance should be taken in harder materials. • A common practice to rapid out of the cut on through holes and to breakout only 2mm past the reaming depth.

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

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

SPECIALS

Tool failure can cause serious injury. To prevent: - When using holders without support bushing, use a shorter reamer to establish the initial hole diameter that is a minimum of 2 diameters deep. - Do not rotate reamers more than 50 RPM unless it is engaged with the workpiece or fixture. Factory technical assistance is available for your specific applications through our Application Engineering Team. ext: 7611 | email: appeng@alliedmachine.com WARNING
