Pros and cons
Pros
- The 4 cm bore and 42 cm length are a focused size for smaller planting jobs rather than wide holes.
- Customer feedback describes ease of use and time saved when planting bulbs and plug plants.
Cons
- The 4 cm diameter limits hole width compared with larger augers, so it is less suited to jobs requiring a wider bore.

What to know before buying
Listing details to confirm
Listing details are inconsistent about the selected product: the title and product details specify a 40 mm by 420 mm bit, while other page content describes 8 cm-wide and longer augers. The supplied information does not confirm that those alternative sizes are included. Check the selected size and drill connection before buying. The hard-soil performance and resistance to rust, bending or breakage are manufacturer claims, not established guarantees.
