Hole saw GRAPHITE 57H936, single piece, 428 g weight

GRAPHITE 57H936 is a single-piece hole saw supplied for cutting round openings in a range of work materials. The tool features a bimetal construction and progressive HSS teeth designed to deliver efficient cutting action when used with a compatible drill or drill driver. The package contains one unit with a weight of 428 g and is intended for users who require a dedicated accessory for producing precise circular holes in metal, wood, plastic and composite surfaces.

Advantages

The bimetal design combines toughness and wear resistance, while progressive high-speed steel teeth provide a balance of fast material removal and edge life. This hole saw is suitable for repeated use on steel and stainless steel as well as softer materials such as wood and plastics, reducing the need to change tools between different tasks. Supplied as a single piece, it is straightforward to mount and use with standard arbors and drill drives.

Suitable for

• Cutting round holes in steel and stainless steel sheets
• Drilling openings in wood for pipe, cable and fixture installation
• Creating holes in plastics and composite panels
• General workshop and maintenance hole-cutting applications

Key specifications

• Construction: bimetal blade with progressive teeth
• Tooth material: high speed steel (HSS)
• Weight: 428 g (single unit)
• Compatibility: designed for use with standard drill/drill-driver and suitable arbor
• Suitable materials: steel, stainless steel, wood, plastics, composite materials

How to use

Fit the hole saw to a compatible arbor and secure it in the chuck of a drill or drill driver. Mark the center of the hole on the workpiece and start drilling at low speed to establish the pilot position. Increase speed as appropriate for the material being cut while applying even forward pressure. Withdraw the saw periodically to clear chips and prevent overheating, especially when cutting metal. After cutting, remove the workpiece and inspect the hole for burrs, deburring if necessary.

Usage recommendations

Use cutting fluid or coolant when drilling metals to extend tool life and improve cutting performance. Select the correct drill speed and apply steady pressure; excessive force or too high speed may reduce tooth life. For plastics and wood, moderate speed and controlled feed produce cleaner holes. Ensure the arbor and drill are correctly rated for the saw size and material.
