Where is the web part of a drill typically thicker?

The web of a drill is typically thicker nearing the shank because this area provides the necessary strength and rigidity to withstand the cutting forces encountered during drilling operations. The thicker web near the shank helps distribute these forces evenly throughout the drill bit, reducing the likelihood of flexing or breaking under load.

In contrast, the areas adjacent to the land and close to the flute are designed to facilitate cutting and chip removal, often requiring thinner profiles to improve cutting efficiency. The tip portion of the drill is tapered to allow for a pointed entry into the material, which also necessitates a thinner design to enhance penetration capabilities. Thus, the design choice for the thickness of the web allows for optimal performance and durability in drilling tasks.
