C.K Tools T3219 bi-metaal gatenzagen-set 20/25/32 mm met zeskantopname

Electricians, plumbers and maintenance technicians often need clean, accurate holes in panels, plasterboard and thin metal. The C.K Tools T3219 hole saw set bundles three common sizes—20 mm, 25 mm and 32 mm—with a hex-shank arbor, so you can switch between diameters quickly on a corded or cordless drill.

Key specifications

• Product type: hole saw set
• Saw type: bi-metal (HSS teeth on alloy steel body)
• Included hole saw diameters: 20 mm, 25 mm, 32 mm
• Number of hole saws: 3
• Arbor included: yes, hex shank

• Tooth pitch: variable (4/6 TPI)
• Packaging: blister pack

Why choose it

Bi-metal construction combines a hardened HSS cutting edge with a flexible alloy steel body, giving you durability and resistance to breakage. The hex shank prevents slipping in the chuck, and the set covers the most requested sizes for cable entry holes, downlight cutouts and pipe penetrations.

Ideal use cases

• Installing downlights in plasterboard ceilings
• Drilling holes for cables or conduits in electrical panels
• Cutting clean openings in wooden enclosures or plastic housings
• Making holes in non-ferrous metals such as aluminium or copper sheet

Good to know

The set is supplied in a blister pack for storage and protection. Always use the correct speed and light feed pressure for the material; for metal, a cutting fluid is recommended. The variable tooth pitch reduces vibration and improves chip clearance.
