## Summary description

GRAPHITE 57H905 is a bi-metal hole saw with a 44 mm cutting diameter, supplied as a single piece. Designed for cutting clean circular holes in metal and other materials compatible with bi-metal construction. Suitable for professional and DIY tasks requiring controlled hole cutting using a drill or drill press.

## Long description

GRAPHITE 57H905 is a bi-metal hole saw with a 44 mm cutting diameter supplied as a single piece. It is designed to cut precise circular holes in steel, stainless steel, wood, plastics and composite materials when used with a drill or drill press. The bi-metal construction combines high-speed steel teeth with a flexible body to balance cutting performance and resistance to breakage.
Advantages
The progressive high-speed steel teeth provide efficient cutting and longer life compared with simple carbon-steel saws. A 44 mm diameter gives a defined, repeatable hole size for installation and modification tasks. The bi-metal design improves durability under varying loads and temperatures while remaining compatible with standard electric drills and drill presses.
Suitable for
Cutting holes in mild steel and stainless steel (thin to medium thickness)
Making openings in wood for installations and fittings
Creating holes in plastics and composite panels
Use with handheld drills and drill presses for workshop or on-site work
When it may not be suitable
This hole saw is not intended for cutting very thick structural steel plates or hardened materials that exceed the capabilities of bi-metal blades. For precision millimeter-critical or ultra-smooth edge finishes, additional finishing with a reamer or sanding may be required after cutting.
Key specifications
Cutting diameter: 44 mm
Material of cutting teeth: high-speed steel (progressive teeth)
Body material: flexible alloy (bi-metal construction)
Quantity: 1 piece
How to use
Mount the hole saw on a compatible arbor and secure it in the drill chuck. Mark the centre of the intended hole and start drilling at low speed to create a pilot impression, then increase speed and apply steady pressure. Use cutting lubricant or coolant when working with metals to reduce heat and prolong tool life. After cutting, remove burrs from the hole edges if required.
What to consider before purchase
Ensure a 44 mm hole meets your installation requirements and fits the intended component
Check that your drill or drill press can accept the required arbor and provide appropriate speed and torque
Consider the material thickness and hardness; very thick or hardened steel may need a different blade type
Usage recommendations
Use moderate drilling speed, apply steady pressure, and employ cutting fluid for metal work. Secure the workpiece and remove chips frequently to maintain cutting efficiency and extend tool life.
