Hole saw (cup saw) c.k tools 424005 — 22 mm diameter

Cup saw c.k tools 424005 — 22 mm diameter is a compact hole saw designed to cut precise circular openings with a 22 mm finished diameter. It is intended for use with a compatible arbor and standard power drills to produce clean holes in materials suitable for its blade type. The tool is commonly used where small round openings are needed for pipe entries, cable glands, fittings or conduit penetrations and is sized for repeatable 22 mm holes.

Advantages

The hole saw provides consistent 22 mm cuts with minimal burring when used at the correct speed and feed. Its compact form factor makes it simple to attach to common drill arbors and does not interfere with access in confined spaces. The cutting edge geometry is optimized for efficient material removal in compatible substrates, reducing the risk of wandering and improving hole roundness. Lightweight construction aids in drill handling and control during repetitive tasks.

Suitable for

• Creating 22 mm openings for cable glands and conduit entries
• Drilling holes for small-diameter pipe or tubing penetrations
• Installing fittings and connectors in electrical and plumbing work
• General trade tasks requiring repeatable small round holes

Key specifications

• Nominal hole diameter: 22 mm
• Tool type: cup / hole saw for use with drill arbor
• Compatibility: fits standard power drills with appropriate arbor
• Application: cutting circular holes in compatible substrates (e.g., soft metals, plastics, wood — dependent on blade material and tooth form)
• Form factor: compact cup design for confined-access drilling

How to use

Fit the cup saw to a compatible arbor according to the arbor manufacturer’s instructions, ensuring the pilot bit (if fitted) and retaining screw are secure. Select an appropriate drill with sufficient torque and set a suitable speed for the work material. Mark the hole centre, position the pilot, and start drilling with steady pressure to allow the saw teeth to cut without excessive binding. Withdraw periodically to remove swarf when cutting deeper material. After cutting, remove the cup saw and deburr the hole edges if necessary.

Usage recommendations

Use cutting speeds and feed rates matched to the work material to extend tool life and improve finish. Wear appropriate personal protective equipment such as eye protection and gloves. For harder materials, confirm the cup saw blade material and tooth form are suitable, and use cutting lubricant where recommended. Inspect the cup saw for damage before use and replace if teeth are worn or chipped.
