Great tool when you have a starting hole

These bits are very aggressive and will still quickly drill any size hole after over a month of use, but the tips wear out very quickly! Makes drilling difficult without a drill pass.

Pros
  • Kit includes: 3 x 4-12/20/32mm HSS step drill bits. We will resend or refund if customer get any quality problem reply! for your trust.
Cons
  • A questionable purchase for the elderly

Variable size for metalworking and multipurpose drill

has worked very well on my projects in wood, aluminum and some sheet metal no problems with bits they seem to edge drill the hole just fine, used ones are available more of these than originally planned, and some of the more expensive brand tiers I've worn in the past have endured.

Pros
  • Material: HSS 4241 (high speed steel)
Cons
  • Was damaged

The best and largest solid/spiral nozzle I've ever used

Surprisingly large, fast and clean! I would still recommend a protective mask with steel rivets. Works great with thin and thick rivets, so I'm assuming stainless steel is no different. It also stays centered even though I use a medium torque impact gun.

Pros
  • Suitable for cutting holes in various materials such as iron plate, aluminum plate, insulation board, PVC film, etc.
Cons
  • I will add later
