Product features
Tool holder is balanced to
G2.5 20,000 RPM
on a HAIMER Tool Dynamic Balancing System from Germany.  Balanced tool holder minimizes the centrifugal forces which minimize the stress on spindle bearing, minimize vibration and maximize the cutting tool's life cycle and greatly improve surface finish.
Unique design feature in the extension nose to minimize the off-balance nature of BT 30 taper specification.  On the side of flange where a half spherical hole is located, a flat is cut into the cylinder nose to compensate the weight of the metal chips lost from forming this spherical hole.  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.  Evenly weight distribution will minimize centrifugal force in high speed spinning and thus maximize the holder's a
bility to hold the cutting tool concentric to spindle rotation.
We use SCM420 alloy steel fro

to la
y the foundation and case harden to RC 57-59 with a core of RC 34-39 to provide good core strength and maximize wear life. The core creates a dampening effect which reduces vibration in high speed milling to improve surface finish
All critical surface are precision ground

0.0002"
TIR from taper to end mill pocket

Each holder comes with a lab certificate on its taper accuracy and runout measurement
Coolant through capability
The AT3 or better taper accuracy ensures 80% or better taper contact with spindle and using Stotz Air/Electronic Gaging for inspection on the taper. All of SHARS CAT/BT/HSK tool
holder use
Stotz
Air/Electronic Gaging for production and finish inspection. Stotz has been chosen by major aircraft companies as the best and most consistent gaging for tool holder shanks
