Ground and Landed Teeth
Alternately Beveled Teeth
Hollow Ground For
Side Clearance
Metric
Sizes
Used for cutting rolled Aluminum and Copper — materials that produce long, stringy chips.
Rake Angle of
Teeth: 10° Positive
Tolerances:
O.D. ±.005; Thickness ±.0005; I.D. +.001 -.000
Closer tolerances available at additional cost.
Alternately beveled
teeth (see sketch)
produce chips of less
than the width of the
slot being cut, elimi-
nating the tendency of
chips to clog.

The two styles of saws shown below are for Commutator Riser Slotting.
These saws are precision ground on all surfaces; dimensions are shown under the
actual size illustrations at right. Formed teeth are on center, with a 15° back-off and 45°
alternate bevel which is 1/3 the width of the tooth. Saws are hollow-ground to provide
clearance between the periphery and the hole.
