What to know before buying
Listing details to confirm
Listing details are inconsistent or incomplete: the size is given as approx. 18*8cm/7.09*3.07 with no unit after the second imperial figure, the drill requirement is described as 8mm without clarifying what that measurement refers to, and the instruction text is incomplete. Confirm these details and compatibility with your drill before buying. Keep the cut oiled, particularly when cutting aluminum, and keep the cutting rod vertical to the sheet as directed.
Who is it for?
A good fit for
- Car repair and maintenance involving sheet materials within the listed thickness limits.
- Users who already have a compatible 8mm electric or pneumatic drill operating at 1500~3000 RPM.
- Metal-sheet work requiring straight or shaped cuts, subject to the listing's stated capacity.
Less suited to
- Buyers who need a standalone powered cutter rather than a drill attachment.
- Jobs requiring material thickness above the listed limits or a cutting radius below 12 mm.
