What cutting tips have extra preheat holes to assist in cutting faster?

Riser cutting tips are designed with extra preheat holes to facilitate faster cutting. The additional holes enhance the ignition of the cutting flame by allowing more oxygen to mix with the fuel gas, which in turn preheats the metal more effectively. This is particularly beneficial when working with thicker materials or when a faster cutting process is required, as it helps maintain the cutting torch's focus and temperature in the cutting zone.

In comparison, other types of cutting tips, such as those designed for rivets, sheet metal, or heavy-duty applications, generally do not incorporate extra preheat holes specifically for increased speed. Rivet cutting tips may prioritize precision and control for smaller rivets, while sheet metal cutting tips are optimized for thin materials. Heavy-duty tips typically accommodate thicker materials but may not inherently have the same configuration of preheat holes as riser cutting tips for enhanced speed.
