Test performed 8-31-2012
We performed a test to compare SX16 1/2" vs ER32 1/2" to see which one provides greater holding power. When milling with a collet chuck torque is key for increasing production. Many suppliers have test data but few use Micro-Grain Carbide End Mill shanks to perform the test. By using End Mill blanks we can achieve a realistic power estimate that can be converted into horsepower.
With 30% less locking torque, SX provides 35% more Radial Driving Torque than ER on a 1/2" Carbide End Mill.
