Long-lasting performance – thanks to cast iron construction

Cast iron is a hard, wear-resistant material that tolerates repeated loading and abrasive contact. The material's rigidity helps maintain cutting geometry under frequent use.

Durable construction reduces the frequency of replacements, making the bit reliable for regular landscaping and fencing tasks.

Consistent hole size – with a 150 mm diameter

A fixed 150 mm cutting diameter produces a predictable bore that matches common planting and post requirements. Consistent diameter reduces the need for re-drilling or widening holes.

Achieves the correct hole width for many outdoor jobs quickly, helping to speed up planting and post installation.

Works across different ground types – with broad soil compatibility

Compatibility with a variety of soils is supported by the combination of robust material and substantial cutting width, which together manage both loose and firmer soils.

Suitable for mixed garden grounds and general-purpose drilling where soil conditions vary from loam to compacted earth.
