C.K Tools T3202A 020 sierra de corona HSS bimetal 20 mm

Cutting clean 20 mm holes through steel, stainless steel, aluminium, copper, brass, wood or plastic can quickly dull ordinary saws and leave rough edges. The C.K Tools T3202A 020 hole saw solves this with an HSS bi-metal construction and variable pitch teeth that stay sharp longer and cut faster, while the 38 mm cutting depth handles most common sheet and pipe work.

Who is it for

Electricians, plumbers, HVAC technicians and metalworkers who need a reliable, general-purpose hole saw for repeated use across mixed materials. It fits any standard 1/2" UNF arbor, including C.K T3200 and T3201 models.

Main features

• 20 mm diameter hole saw with HSS bi-metal teeth for durability and high precision.
• Variable pitch tooth design reduces vibration and clogging when cutting steel, stainless steel, aluminium, copper, brass, wood and plastic.
• Welded construction for strength and long service life.
• 38 mm maximum cutting depth for sheet metal, pipe and timber.
• 1/2" UNF thread fits common arbors; use with C.K T3200 or T3201 for a secure hold.

Tips

Use a slow speed and cutting fluid when drilling stainless steel to extend tooth life. For wood and plastic, a faster speed gives a cleaner cut. Always secure the workpiece and use a pilot drill if your arbor includes one.
