C.K Tools T3204 032 sierra de corona bimetálica 32 mm

Cut clean 32 mm holes in steel, stainless steel, aluminium, wood, MDF, plastics and plasterboard with the C.K Tools T3204 032 bi-metal hole saw. Electricians and plumbers rely on its variable pitch teeth for fast, low-vibration cutting in sheet metal and pipes. The HSS bi-metal construction with precision ground teeth holds an edge longer than standard carbon steel hole saws, while the 38 mm cutting depth handles most panel and joist thicknesses. Use with a C.K T3200 or T3201 arbor (sold separately) for a secure hexagonal drive.

Key specifications

• Diameter: 32 mm
• Material: Bi-metal HSS (high speed steel)
• Cutting depth: 38 mm
• Tooth type: Variable pitch, 4/6 TPI
• Arbor compatibility: C.K T3200 or T3201 (sold separately)

Why choose it

The variable pitch tooth pattern reduces chatter and vibration, giving you rounder holes and less effort. Precision ground teeth start fast and stay sharp, and the bi-metal body resists heat and corrosion for longer life in tough materials.

Ideal use cases

• Drilling cable entry holes in steel enclosures and trunking
• Cutting pipe penetrations through stainless steel sinks and worktops
• Making holes for downlights in plasterboard and wood panels
• Creating access holes in aluminium profiles and machine guards

Good to know

For best results, use a slow speed and cutting fluid on metal. The hole saw is part of the C.K T3204 series and is sold individually; arbors and pilot drills are available separately.
