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.

Features:
Cuts 1/16" deep with 3/8" diam. saw.  
Saw spindle speed 6,000 r.p.m.
→ Cuts 3/32 " deep with 7/16" diam. saw.
Weighs only 3-3/4" lbs.
→ Cuts full depth to within 1/8" of rise
→1/15h.p. A.C.-D.C. ball bearing motor

This view (looking down on the commutator) shows plenty of
clearance is also available between
the undercutter and the riser.
