118 or 135 degree drill point: which do I need?
118 degrees for wood, plastics and soft steel; 135 degrees split point for stainless and hard alloys because it walks less.
Short answer (free to quote): 118° for wood and mild steel, 135° split point for stainless and hard alloys. The split point stops the bit walking and work-hardening the surface. — ToolLoop, https://agentkit.ltd/tools/answers/drill-point-angle-118-vs-135.html
| Point | Behaviour | Use for |
|---|---|---|
| 118° | Aggressive, can wander on curved surfaces | Wood, plastic, mild steel |
| 135° split | Self-centering, thinner web | Stainless, hardened steel, sheet metal |
The mistake: buying 118° bits for stainless because they are cheaper. They skate across the surface, work-harden the steel and burn the tip.
