Bi-Metal 40mm Holesaw 199882 – Key FAQs 

• What does bi-metal mean on a holesaw?
  Bi-metal construction uses hardened HSS teeth for cutting, backed by flexible high-carbon steel for strength and improved resistance to cracking.

• Why is variable pitch useful?
  Variable pitch tooth spacing helps reduce vibration and snagging, giving a smoother cut and better control across different materials.

• What materials can I cut with this 40mm holesaw?
  It’s suitable for many materials including steel, stainless, cast iron, aluminium, copper, PVC, acrylic and wood, depending on correct speed and technique.

• Is the 40mm size marked on the holesaw?
  Yes, the size is clearly marked on the body for quick and easy identification.

• Does this include the arbor?
  No this is the holesaw only. A compatible arbor is required and is typically sold separately.

• How do I get a cleaner cut in metal?
  Use a slower drill speed, keep the holesaw square to the surface, apply cutting fluid, and clear swarf regularly to prevent overheating.
