Hole saw GRAPHITE 57H917 bi-metal 114 mm

GRAPHITE bi-metal hole cutter 114 mm is designed for cutting precise circular openings in a range of materials including steel, stainless steel, wood, plastics and composite materials. The tool is supplied as a single piece and is intended for use in plumbing, electrical and HVAC installations as well as general metalworking and construction tasks.

Advantages

The bi-metal construction combines high-speed steel cutting edges with a flexible alloy body, offering improved wear resistance and longer life compared with simple carbon-steel cutters. Progressive teeth geometry helps produce cleaner cuts and reduces vibration during cutting, while the 114 mm diameter provides a sizeable aperture for pipe, conduit and ductwork penetrations.

Suitable for

• Cutting holes in mild steel and stainless steel
• Creating openings in wood and wooden panels
• Working with plastics and composite panels
• Plumbing, electrical and HVAC installation work

When it may not be suitable

This hole cutter is not intended for continuous heavy-duty production cutting on very large industrial presses; in such cases, purpose-built industrial tooling may be preferable. It is also not designed for cutting very hard exotic alloys or reinforced concrete.

Key specifications

• Diameter: 114 mm
• Material: bi-metal with high-speed steel cutting edge
• Teeth: progressive tooth geometry for cleaner cuts
• Supply: single piece (1 pc)

How to use

Mount the hole cutter on a compatible arbor or drill with appropriate support and secure the workpiece. Start at low speed to position the cutter, then apply steady pressure and increase speed as needed according to the material. Use cutting lubricant when working with metal to extend tool life and reduce heat. After cutting, clear swarf and inspect the edge before further use.

What to consider before purchase

• Ensure 114 mm diameter matches the required opening size
• Verify compatibility with your drill or arbor and the required shank type
• Consider material thickness and hardness of the workpiece
• Plan for appropriate cutting lubricant and safety equipment

Usage recommendations

For best results when cutting metal, use low to medium drill speeds, steady feed pressure and cutting lubricant; for wood and plastics, higher speeds may be used but avoid excessive heat build-up.
