ISO 30 ER32 Collet Chuck Tool Holder Balanced to 20,000 RPM This is a brand new unused collet that I purchased here on eBay that ended up being the wrong size. Product features: Dynamically balanced to 20,000RPM at G2.5 by Haimer balancing machine at all location for consistent balance Unique design feature in the extension nose to minimize the off-balance nature of CAT 40 taper specification. On the side of flange a flat is cut to compensate the weight of the metal chips lost. This design allows the left side and right side of the holder to achieve 50-50 perfect weight distribution in its upright position, like the position inside a machine spindle. Symmetrical design in evenly weight distribution will minimize centrifugal force in high speed spinning and thus maximize the holder's ability to hold the cutting tool concentric to spindle rotation Product Specifications: Taper: ISO3 Rear Thread Size: M12 x 1.75 Collet Series: ER32 Range: 1/8-3/4" Projection (L): 60mm Nose Diameter: 50mm Runout: .0001" Balanced to 20,000 RPM In a generic standard ER collet nut, an internal ring is off-centered so that an ER collet can be easily snapped into it and holds the ER collet in place. To minimize this off-centering, SHARS ER collet nut is optimized to distribute the flat sides' area to off-set the off-center. ER Collet Nut is also balanced to 20,000 RPM Manufactured from alloy steel with good core strength and long wear life. Taper shank is case hardened to 56-60 HRC and has a core hardness of 35-40 HRC. The case hardness is designed to give maximum wear life without compromising the 60-62 HRC spindle. The core creates a damping effect from the vibration during the high speed milling, especially in long reach or heavy duty milling application Taper ground to AT3 or better accuracy standard for maximum contact with spindle. All of SHARS CAT/BT/HSK tool holder use Stotz Air/Electronic Gauging for production and finish inspection. Stotz has been chosen by major aircraft companies as the best and most consistent gaging for tool holder shanks ll critical surface are precision ground Concentricity is less than 0.0001" from taper to end mill pocket Each holder comes with a lab certificate on its taper accuracy and run-out measurement Coolant through capability Collet nut thread is precision ground Please review the photos for accurate description Photos are actual Collet 1-Day Handling (weekdays) Shipped USPS Priority Mail
