Hole saw c.k tools 424001 16 mm — bi-metal cutting cup for metal and wood

Hole saw c.k tools 424001 16 mm is a bi-metal cutting cup designed for creating precise small-diameter holes in thin metal, wood and selected plastics. The 16 mm diameter and bi-metal construction provide a balance between cutting performance and edge life, making this cutting cup suitable for repetitive drilling tasks. The tool fits standard drill chucks and arbors used in installation, electrical work, plumbing and general maintenance where controlled circular holes are required.

Advantages

The bi-metal cutting edge combines flexibility and hardness to resist wear while maintaining cutting sharpness for multiple cuts. Its 16 mm size enables accurate small holes with minimal material removal and clean edges. Compatibility with standard drill chucks and arbors allows fast mounting and secure operation on common cordless and corded drills. The design reduces wobble and improves cut concentricity when used with a proper arbor and pilot bit, contributing to consistent hole quality across repeated operations.

Suitable for

• Drilling small holes in thin sheet metal for cable entries and fittings
• Creating precise holes in wood for dowels, bushes and small fittings
• Cutting openings in plastics for conduit or fasteners
• Maintenance and repair tasks that require repeatable 16 mm holes

Key specifications

• Cutting diameter: 16 mm
• Material: bi-metal construction for the cutting edge
• Intended materials: thin metal, wood, selected plastics
• Compatibility: standard drill chucks and arbors
• Typical uses: installation, electrical work, plumbing, general maintenance

How to use

Secure the cutting cup onto a compatible arbor or into the drill chuck, ensuring the pilot bit (if fitted) is centered. Clamp the workpiece or ensure it is stably supported to prevent movement. Use an appropriate drill speed for the material: lower speeds for metal, higher speeds for wood and plastics, applying steady pressure without forcing the tool. Withdraw periodically to clear chips and reduce heat build-up. After cutting, deburr the edge of the hole if required.

Usage recommendations

For best results when cutting metal, use cutting lubricant and low-to-moderate drill speed. For wood and plastics, use higher speeds with consistent feed. Always wear appropriate eye and hand protection and secure small workpieces to prevent spinning. Inspect the cutting edge before use and replace the cup if teeth are damaged or excessively worn.
