CMT 317.250.12 Hinge Boring Bit 25 x 57.5mm LH Collated Exterior Wood Screws How does the double nut

How does the double nut backlash design improve milling accuracy

reducing field labor and simplifying installation

giving the operator real-time positional feedback and automated table movement for improved accuracy and surface quality

combining rigidity with field-adjustable leveling capability

The combination of Dura-Carbide tips and an optimized four-flute flute design addresses the two most common causes of premature bit failure - heat buildup and impact stress - so you spend less time changing bits and more time drilling
