Martindale Close-Cut Undercutter |
|
The Close-Cut Undercutter was specially designed to
finish off a mica slot when it is necessary to cut within 1/8" of a riser.
This unit has a straight solid shaft and needle bearings, both front and
rear, for smoother operation.
While this small machine can be used for undercutting the full length of
smaller commutator slots, one of the more substantial Martindale
Undercutters should be used on larger commutators for most of the cut and
Close-Cut used for the remaining end against the riser.
Though we hesitate to recommend carbide saws in any hand-held undercutter,
we have had success with them in this smaller unit. |
Design of the Close-Cut allows ample clearance between
the undercutter and the commutator surface on even the largest commutators. |
