MAGNET HOLDER FOR CORE BIT RETIPPING
Features:
The retipping magnet are made of strong N35EH neodymium magnet with strong magnitizm but also high resistance for heat. In the meantime, the retipping magnet are perfect for position the drilling segment in percise side clearance. Also the inner side clearance can be adjust when you put the magnet in its' a, b, c, d position.
Application:
For core drill bit retipping, core drill repair & DIY
4 side clearance available
Strong magnet for resisting high temperature
72.5mm overal length
With N35EH neodymium magnet
a position side clearance: 0.50mm
b position side clearance: 0.75mm
c position side clearance: 1.0mm
d position side clearance: 1.25mm
The rule of segments brazing:
Inner Side clearance = (Segment width- steel core width) x 0.4
Outer Side clearance = (Segment width - steel core width) x 0.4
Following is the reference for the segment size and steel core width for different diameter
