Hole saw GRAPHITE 57H911 — pack 1 pc, weight 200 g

GRAPHITE 57H911 hole saw is a single-piece cutting tool supplied as 1 pc with a package weight of 200 g. It is a bimetal hole cutter with progressive teeth made of high-speed steel, designed to cut precise circular openings in a range of materials including steel, stainless steel, wood, plastics and composite materials. The tool is suitable for installation tasks such as making holes for pipes, cables and fittings in construction, renovation and maintenance work.

Advantages

The bimetal construction combines a flexible body and a hardened cutting edge to resist wear and bending during demanding cuts. Progressive tooth geometry improves chip evacuation and reduces cutting load, which results in smoother cutting action and longer service life. High-speed steel teeth maintain sharpness when working with metal and provide reliable performance on wood and plastics. Supplied as a single unit, the hole saw is compact and easy to store or transport.

Suitable for

• Cutting round openings in thin to medium-thickness metal sheets and stainless steel
• Creating holes in wooden panels and timber for installations
• Cutting openings in plastic and composite panels for cables and fixtures
• Installation and renovation tasks requiring accurate circular holes for pipes, conduits and fittings

How to use

Attach the hole saw to a compatible mandrel or arbor and secure it firmly before starting work. Mark the center point of the intended opening, position the pilot drill or centering bit, and start drilling at low speed to establish the cut. Increase speed moderately while maintaining steady pressure; avoid excessive force that could overload the tool or arbor. For metal cutting, use cutting fluid or coolant to reduce heat and extend tooth life. Clear chips periodically to prevent clogging and ensure a consistent cut. After completing the hole, remove the slug carefully and inspect the cut edge for burrs, deburring if necessary.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Select the correct mandrel size and drill speed for the material being cut. For prolonged metal cutting, apply cutting lubricant and allow intermittent cooling breaks to preserve cutting edge life.
