Usage tips
When you start the cut place the hole saw against the surface and begin at a slow speed to avoid grabbing, then ease into the material as the teeth engage. In softer materials aim for a steady, even feed and avoid forcing the blade. If you are drilling through stainless or mild steel, keep the drill steady and apply light pressure, allowing the 30% extra gullet volume to maintain a clear path for chips. Remember to lubricate appropriately for metals to extend blade life and reduce heat buildup. For wood and plastics, ensure the surface is flat and stable and maintain a consistent cutting pace to achieve a clean edge. The six piece pack provides a ready-to-use option for multiple sizes and tasks, helping you avoid repeated tool changes during a project. The blades are engineered for practical performance, so you can rely on steady cuts across a variety of materials. © Starrett quality is built into a toolset that prioritises durability and value for money, making these blades a sensible option for professional trades and DIY enthusiasts alike. ✨
