Abstract
A method and device for magnetizing a tool bit. A housing is adapted for removably fitting around a magnetically attractive tool bit, and a plurality of magnets are disposed in the housing and adapted for making contact with the surface of the bit, to strengthen the magnetic coupling of the magnets to the bit. The device preferably remains on the bit while employing the bit, and is especially adapted for high speed use.
Claims6
A magnetizing device for use with a magnetically attractive tool bit having a predetermined size, comprising:
- a housing;
- and
- a plurality of magnets disposed at least partially within said housing, said magnets each having a north pole and a south pole, a same one of said north pole and said south pole of each of said magnets being disposed proximate one another, wherein said magnets are spaced apart by the magnetic fields thereof and form an opening that is larger than the predetermined size of the bit, said housing and said magnets being adapted in cooperation to permit at least one of said magnets to move into contact with the bit when the bit is placed through said opening.
