About this item
- ★ Hole Saw Size --- Hole saw diameter: 140mm/5-1/2 inch; center drill bit diameter: 6mm/0.24 inch; shank diameter: 7.5mm/0.3 inch; cutting depth: 30mm/1.18 inch; overall length: 100mm/3.94 inch
- ★ Wide Applications --- Suitable for thick metal material, such as stainless steel, high carbon steel, cast Iron, copper, and aluminum, for automotive and boat repair and modification enthusiasts to use as professional tools. It is not recommended for use with softer materials such as plastics and woods
- ★ Special Coating --- Processed by CVD (chemical vapor deposition), with high hardness, high elastic modulus, high thermal conductivity, good self-lubrication and chemical stability
- ★ Good Feature --- M42 delivers with exceptional thermal integrity and heat resistance due to its high cobalt content (8%). This enables superior cutting performance and wear resistance at high temperatures,offering outstanding edge retention, abrasion resistance, and longer tool life when machining tough, abrasive, or hard materials like stainless steels
- ★ Useful Tips --- Do not touch the hole saw immediately after drilling because the temperature is too high. Add coolant or water when drilling metal. If Wear gloves and masks as needed and keep drilling slowly as the center drill passes through the material. If the hole saw encounters unusual resistance or vibration during operation, stop drilling immediately

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
