Hardened High-Speed M42 Tool Steel
- Yield Strength: Not Rated
- Hardness: Rockwell C65 (Very Hard)
Also known as cobalt steel, this M42 tool steel maintains its hardness in high-speed cutting applications that generate intense heat. Use it to make tools for cutting extremely hard materials.

Tight-Tolerance Multipurpose Air-Hardening A2 Tool Steel Rods
Precision ground and held to a strict straightness tolerance, these rods are ready for turning in your lathe. They’re also known as drill rod. A2 tool steel is more wear resistant than O1 and it keeps a sharper cutting edge. This air-hardening material is widely used for punches, broaches, and dies.

Spot Welding Electrodes
Press these electrodes onto the tips of spot welders to change the size and shape of your weld. Their shank is tapered for easy press-fit installation.
Pointed electrodes are the most common electrodes. All are good for most applications, including small welds. Those with offset tips are best for spot welding near edges and corners. Flat electrodes create larger welds than pointed electrodes and are best when the weld appearance is less important.

Cap-Style Spot Welding Electrodes
A two-part alternative to standard electrodes, these electrodes reduce waste since you can reuse the shank. For a complete electrode, you'll need a tip and a shank (both sold separately). Press complete electrodes onto the tips of spot welders to change the size and shape of your weld. When the tip becomes worn, only the tip needs to be replaced.
Pointed tips are the most common. They’re good for most applications, including small welds. When used with water-cooled spot welders, female tips are less likely to spill water than male tips when swapping them out.
Flat tips create larger welds than pointed tips and are best when the weld appearance is less important.
