Abstract
Microtrenching blades and methods of manufacturing the same. A blade a first blade portion comprising a center arbor bore defining a hole through the blade and a second blade portion comprising a plurality of blade segments, wherein the second blade portion is distal to the first blade portion relative to the center arbor bore. The blade includes a plurality of blade scoops disposed around a perimeter of the blade. The blade is such that the plurality of blade segments and the plurality of blade scoops are arranged such that two of the plurality of blade segments are separated by a blade scoop.
Claims20
A blade comprising:
- a first blade portion comprising a center arbor bore defining a hole through the blade;
- a second blade portion comprising a plurality of blade segments, wherein the second blade portion is distal to the first blade portion relative to the center arbor bore, the plurality of blade segments forming a cutting edge;
- and
- a plurality of blade scoops disposed around a perimeter of the blade, wherein each of the plurality of blade scoops is defined by a sidewall and comprises a width;
- wherein the plurality of blade segments and the plurality of blade scoops are arranged such that two of the plurality of blade segments are separated by a blade scoop;
- wherein the second blade portion further comprises a cutting edge defined around the perimeter of the blade, and wherein the plurality of blade segments further comprises a plurality of cutters attached to the cutting edge;
- wherein the cutting edge comprises a width and a centerline;
- wherein three or more of the plurality of blade segments are each attached to the cutting edge of the blade body at a different position across the width and at a different position relative to the centerline of the cutting edge of the blade body;
- wherein the width of the blade scoop tapers from the first blade portion to the second blade portion;
- and
- wherein a first portion of each of the plurality of blade scoops is a leading edge and is located opposite a second portion of each of the plurality of blade scoops, and the second portion is a thicker width than the first portion and forms a scoop sleeve.
