MALAYAS3Pcs HSS Step Cone Drill Titanium Coated Hole Cutter Bit Set 4-12 20 32mm Tools Accessories

I wanted it for drilling drainage holes in plastic plant pots, and the drill bit did the job well, even with my not very high-powered old cordless drill. Very happy with it for this purpose, couldn't say if it could handle harder materials - you'd probably need to drill a pilot hole first to get it started.

Good value and reasonable quality for the price, numbers were a bit faded though

Very good tool it works really well, great value for money.

I purchased cone drill set to drill a 20mm hole to match an arbour. Unfortunately the 32mm diameter core drill stamped at 20 mm was measured 19.6mm diameter. Luckily having reset the drill 20mm hole was able to be achieved using the 20mm cone drill.

Good quality and worked well on a drum machine I was modding

Good bit of kit cheap for what they are don't expect them to last for ever i use them on plastic trucking and are perfect for that job not great through metal but would buy again

Tha item is very good. Solid and works great

Cheap, did the job I need to do, but haven’t lasted the time
