## Long description

Proline Hole Saw 105 mm bimetal (model 28105) is a circular cutting tool designed for creating large-diameter openings in metal, wood and selected plastics. The 105 mm diameter provides an effective solution for through-holes needed in plumbing, HVAC, electrical installations and carpentry. Bimetal construction combines a hardened cutting edge with a flexible body to reduce breakage while maintaining cutting performance when used with handheld drills and drill presses.
Advantages
The bimetal blade offers a balance of wear resistance and toughness, enabling longer service life compared with high-speed steel alone. A 4/6 TPI tooth pitch is optimized for cutting both thin and thicker materials, reducing burr formation and improving chip evacuation. The saw is compatible with common arbors and pilot drills used on portable drills and drill presses, allowing precise, repeatable holes. The 105 mm diameter covers a wide range of large-opening requirements without the need for multiple smaller saws.
Suitable for
 Cutting circular openings in metal sheets and conduit for plumbing and HVAC installations
 Creating cable and pipe access holes in wooden panels and studwork for electrical work
 Making service access or ventilation openings in thin plastic panels and enclosures
 Workshop and on-site drilling with handheld drills or drill presses
Key specifications
 Cutting diameter: 105 mm
 Tooth pitch: 4/6 TPI (teeth per inch)
 Material: bimetal construction for the cutting edge and body
 Intended materials: ferrous and non-ferrous metals, wood, selected plastics
 Compatible with standard drill arbors and pilot bits for stability during cutting
How to use
Secure an appropriate arbor and pilot drill in the hole saw and mount the assembly into a drill or drill press. Mark the center of the intended hole and clamp the workpiece to prevent movement. Start drilling at low speed to establish the pilot hole and maintain steady pressure; increase speed as the saw bites into the material while avoiding excessive force that can overheat the blade. Periodically withdraw the saw to clear chips and allow cooling. After cutting, deburr the hole edges as needed.
Usage recommendations
Use cutting oil or lubricant when drilling metals to extend blade life and improve cut quality. For thicker materials, apply moderate feed rate and consider stepping cuts or backing support to reduce chatter. Match the arbor and pilot bit diameter to the hole saw and verify compatibility with your drill chuck or press arbor before operation.
