Kmils Multipurpose Hole Core Cutter Saw Drill bit for Ply wood work , Plastic and PVC sheets | 16 Pieces

Got it today and I used to make 2inch holes on pvc pipe for aquaponics. Well I drilled 2 holes and 2 of them arent smooth and I struggled to expell the plastic piece stuck inside the drill bit.Then I realized the rotation should be anticlock wise. Fortunately my drill machine has a switch to change the direction. After that making hole was so easy and every hole came perfect. The chunk piece didnt stuck inside the drill bit.However, take care performing the drilling. At first make small holes using the drill screw provided in clock wise direction then drill the actual hole in anticlock wise direction.I dont know if it is the right method or the design is faulty. In anticlock direction (screw mode) making the small central hole was difficult but the sawing was quite easy...If you find difficulty in drilling big holes, try to reverse the drill machines rotation.Made in china and there is no instruction provided in the box.The seller took one week to pack it 😆🤣😂 I thoght he is actually making the tools as fresh, but the made in China text spoiled everything.. So -1*

It's suitable for occasional light diy jobs only. You need a high capacity drill for the job done which most of us don't have

Could be cheaper in price

the cutters are good. The only hitch is it will not be useful to cut thick sheets i.e more than 20-25 mm

I have installed cylindrical door lock with this kit with ease in 30mm ply door.

Quality of case is very poor

Not great product. Saw wheels seems to be good, i used to cut the hole in 10mm acrylic sheet. It cuts, problem with the bit/saw holder, it is very cheap quality. Difficult to hold the drilling bit, comes out easily while cutting.
