In other embodiments, the locking element 14a can be attached to the shaft 12a by other fastening methods. The washer 14b can be arranged to be slidable relative to and over the locking element 14a.The locking tab 14c of the locking element 14a can be configured to connect to and be held in the cavity 12e of the shaft 12a, thereby securing the locking element 14a to the shaft 12a. When the washer 14b is positioned above the locking element 14a adjacent to the cavity 12e at location 14d, the locking element 14a can be compressed and the locking tab 14c can connect to the cavity 12e. During the installation of the wear-resistant reinforced cutting tool 10 in a bore (not shown) of a rotating drum (not shown), the washer 14b can be moved along the locking element 14a from a location 14d adjacent to the cavity 12e to a second location 14e adjacent to the holder 12c of the tool body 12. This movement of the washer 14b can cause the locking element 14a to expand into a surface of the bore of the rotating drum.

[0014] The hardness of the carrier 16 can be greater than that of the tool body 12. The carrier 16 can have a material hardness of at least 58 Rockwell hardness C (HRC). In one embodiment, the carrier 16 can be made of sintered tungsten carbide (WC-Co alloy) having a cobalt content of about 5 to about 13 percent by weight.

In one embodiment, the plurality of wear-resistant elements 18 can be made of sintered tungsten carbide (WC-Co alloy) having a cobalt content of about 5 to about 13 percent by weight. In other embodiments, the plurality of wear-resistant elements 18 can consist of different materials with different hardnesses. The plurality of wear-resistant elements 18 can be fixedly attached within the insert seat 12g to the surfaces 12h, 12i, and 12j of the tool body 12. In one embodiment, the plurality of wear-resistant elements 18 can be brazed within the insert seat 12g to the surfaces 12h, 12i, and 12j of the tool body 12.In other embodiments, the plurality of wear-resistant elements 18 within the plate seat 12g can be attached to the surfaces 12h, 12i, and 12j of the tool body 12 using different fastening methods. The plurality of wear-resistant elements 18 can comprise three semicircular plates, each covering 120 degrees (120°) of the circumference of surface 12i of the tool body 12, to collectively cover the entire circumference of surface 12i of the tool body 12. In other embodiments, any number of abutting wear-resistant elements 18 of different sizes and shapes can be used to cover the entire circumference of surface 12i of the tool body 12. The plurality of wear-resistant elements 18 can extend from surface 12j of the tool body 12 to the end 12m of surface 12i of the tool body 12 and adjacent to section 16c of the support 16.In this way, the multitude of wear-resistant elements 18 can completely cover and reinforce the entire surface 12i of the tool body 12. In other embodiments, any number of abutting wear-resistant elements 18 can be used to jointly cover and reinforce different surfaces of the tool body 12.

[0016] The hardness of the cutting tip 20 can be greater than that of the tool body 12. The cutting tip 20 can have a material hardness of at least 58 Rockwell C (HRC). In one embodiment, an end 20a of the cutting tip 20 can be made of a different material than a substrate 20b of the cutting tip 20. The end 20a of the cutting tip 20 can be made of a harder material than the substrate 20b of the cutting tip 20, both of which can have a greater material hardness than the tool body 12. In one embodiment, the substrate 20b of the cutting tip 20 can be made of sintered tungsten carbide (WC-Co alloy) having a cobalt content of about 5 to about 13 percent by weight, and the end 20a of the cutting tip 20 can be made of polycrystalline diamond. In other embodiments, the cutting tip 20 can be made of different materials with different hardnesses.The cutting tip 20 can be fixedly attached within and to a plate seat 16e of the carrier 16. An upper section 20c of the cutting tip 20 can protrude from the plate seat 16e of the carrier 16. In one embodiment, the cutting tip 20 can be brazed within and to the plate seat 16e of the carrier 16. In other embodiments, the carrier 16 can be attached within and to the plate seat 16e of the carrier 16 using different fastening methods.

[0017] The head 10a of the wear-resistant reinforced cutting tool 10 can comprise the holder 12c, the support 16, the plurality of wear-resistant elements 18, and the cutting tip 20. The head 10a of the wear-resistant reinforced cutting tool 10 can have a length 10b extending from an end 12o of the holder 12c to the end 20a of the cutting tip 20. The maximum diameter of the head 10a of the wear-resistant reinforced cutting tool 10 can include the outer diameter 12k of the holder 12c. A length 18a of the plurality of wear-resistant elements 18 can cover at least 10% to 70% of the length 10b of the head 10a of the wear-resistant reinforced cutting tool 10. A strength 18b of the multitude of wear-resistant elements 18 can be between 3% and 30% of the outer diameter 12k of the bracket 12c.In other embodiments, the dimensions of the head 10a of the wear-resistant reinforced cutting tool 10, including its components, may vary.

[0018] When the wear-resistant reinforced cutting tool 10 is mounted on a rotating drum (not shown), the shank 12a can be inserted into a locking system (not shown) of a bore in the rotating drum, thereby allowing the washer 14b to be moved from the point 14d adjacent to the cavity 12e of the shank 12a to the second point 14e adjacent to the holder 12c of the tool body 12. During this movement, the locking element 14a can expand outwards against a surface of the bore in the rotating drum, thus locking the locking element 14 against the locking system of the bore in the rotating drum due to friction.In this way, the wear-resistant reinforced cutting tool 10, including the locking element 14 and the attached shaft 12a, can be attached to the rotating drum by means of the locking tab 14c held in the cavity 12e of the shaft 12a, so that it is designed to rotate with the rotating drum during cutting or operation of the rotating drum. To enable the use of the locking tab 14c for effectively locking the wear-resistant reinforced cutting tool 10 to the drum, the mass of the head 10a of the wear-resistant reinforced cutting tool 10 can be kept as low as possible.The use of one or more hard, but relatively low-mass, wear-resistant elements 18, compared to the hard, but high-mass carriers 16, for reinforcing the tool body 12 at the critical points of the holder 12c, can enable the use of the less hard and less dense material of the tool body 12 to keep the mass of the head 10a of the wear-resistant reinforced cutting tool 10 at a manageable level. In one embodiment, the hard, but high-mass carrier 16 can have a density between 14 and 15 grams per cubic centimeter, a hardness greater than 58 HRC, and a volume 1.5 to 5 times larger than the at least one wear-resistant element 18. The at least one wear-resistant element 18 can have a hardness and density comparable to the carrier 16. The holder 12c of the tool body 12 can have a density of 7.2 to 8.2 grams per cubic centimeter.This allows for the provision of a mass-effective reinforcement system that utilizes a carrier 16 and one or more wear-resistant elements 18, which exhibit superior wear properties compared to the material of the tool body 12, to reinforce the tool body 12 of a cutting tool 10 to protect it from wear and erosion during a cutting operation. This can protect the tool body 12 of the cutting tool 10 from being washed out and causing failure of the cutting tool 10, thus preventing the resulting undesirable cutting pattern of a failing cutting tool 10.

[0019] The Fig. Figures 4-5 illustrate assembled and disassembled views of another embodiment of a wear-resistant reinforced cutting tool 110. The wear-resistant reinforced cutting tool 110 can be used for earth cutting operations in road construction. In other embodiments, the wear-resistant reinforced cutting tool 110 can also be used in other types of cutting operations. As described in the Fig. As shown in Figures 4-5, the wear-resistant reinforced cutting tool 110 can be identical to the wear-resistant reinforced cutting tool 10 of the embodiment of the Fig. 1-3, except that the plurality of wear-resistant elements 118 may only comprise two non-abutting, semicircular plates that cover only a portion of the circumference of the surface 112i of the tool body 112. In other embodiments, the wear-resistant reinforced cutting tool 110 may employ at least one wear-resistant element 118 that covers only a portion of the circumference of the surface 112i of the tool body 112. In one embodiment, for example, the at least one wear-resistant element 118, which may comprise a plurality of non-abutting wear-resistant elements 118, may be used to cover more than 40% but less than 100% of the circumference of the surface 112i of the tool body 112. In other embodiments, the at least one wear-resistant element 118 may cover a varying percentage of the circumference of the surface 112i of the tool body 112.In other embodiments, the at least one wear-resistant element 118 can have different configurations for covering different surfaces of differently designed cutting tools 110.

As shown in the Fig. 6-8 together, the wear-resistant reinforced cutting tool 210 can be combined with the wear-resistant reinforced cutting tool 10 of the embodiment of the Fig. 1-3 are identical, except for the following points: (1) only one wear-resistant element 218 is used, comprising a ring that covers the entire circumference of the surface 212i of the tool body 212, and (2) the surface 212h of the insert seat 212g is significantly shorter. In one embodiment, the surface 212h of the insert seat 212g is 0-50% of the height of the surface 212i. In other embodiments, the wear-resistant element 218 can have different configurations to cover different surfaces of differently shaped cutting tools 210.
