Abracs Holesaw - 44mm

M42 HSS bi-metal is a type of high-speed steel known for its hardness and heat resistance. The addition of 8% cobalt further enhances these properties, making the holesaw extremely durable and capable of cutting tougher materials.

You can use most standard electric drills (corded or cordless) with a suitable chuck. A variable speed drill is recommended for optimal control, especially when cutting different materials.

For metal cutting, a dedicated cutting fluid or oil is recommended. For wood or plastics, lubrication is less critical but can help reduce friction and heat. Water can be used as a coolant for some plastics.

Use the correct drill speed for the material, apply steady pressure, and ensure the holesaw is sharp and clear of debris. Using a pilot bit for starting can also improve accuracy.

This holesaw is designed for cutting steel, stainless steel, wood, and plastics. Always ensure you are using appropriate speeds and lubrication for the specific material.

The lifespan depends heavily on the frequency and type of use, as well as proper maintenance and operating technique. The M42 HSS bi-metal construction with cobalt offers extended durability compared to standard holesaws.

Typically, the arbour (the shaft that holds the holesaw and fits into the drill) is sold separately. Please check the product listing to confirm if an arbour is included.

Ensure correct drill speed and adequate lubrication. Check if the teeth are dull or damaged. Verify the workpiece material is within the recommended range.

Reduce drilling pressure and ensure the gullets are clear of debris. Try backing the saw out periodically to clear chips. Check for warpage in the workpiece.

Reduce drill speed and increase the amount of cutting fluid or lubricant. Allow the holesaw to cool down between cuts.

Use a pilot drill bit to guide the holesaw. Score the surface lightly with a scribe before drilling. Ensure the workpiece is stable.
