While carbide inserts may have a higher upfront cost, they offer excellent value by providing four usable cutting edges per insert and significantly reducing time spent on tool sharpening.

Carbide cutters excel at machining difficult materials such as cold-rolled steel, stainless steel, and bronze, delivering consistent performance and long tool life. They are also compatible with aluminum, brass, and leaded steels—though for these softer materials, a finely honed high-speed steel tool may still yield the best surface finish.

This is the 10-pack of replacement carbide inserts for the following tool holders:

• 80° Carbide Tool Holders
• 80° RH 3/8" Boring Bar
• 80° LH 3/8" Boring Bar
• 80° RH 3/8" Boring Bar w/2 Flats
• 80° LH 3/8" Boring Bar w/2 Flats
