300 mm Mini Excavator Auger Bit

The 300 mm diameter of this auger bit targets drilling jobs where the volume of extracted soil must be removed without clogging. The helix is sized for this caliber, and the attachment must be checked directly against the machine interface: KX36-3, KX41-2, and JCB 801 are cited as compatibility references, but this does not replace a check of the axle spacing and drive.

Checkpoints before mounting

• Diameter: 300 mm – suitable for planting holes, post setting, piles, or drainage.
• Helical geometry – designed to bring debris up and out of the hole.
• Interface to verify – compatibility depends on the adapter and the carrier machine's drive.
• Cutting tip – included to start the hole in the first few centimeters.

Before ordering, measure the bolt spacing and attachment type on your mini excavator. A 300 mm bit demands more torque than a smaller diameter; matching the auxiliary hydraulic flow to the drive system remains the primary factor for proper operation.

Calibrated holes and spoil removal

The spiral helix lifts soil in successive passes. In compact ground, the 300 mm diameter requires a steady penetration rate to avoid overloading the spiral. The replaceable tip can be swapped out when worn, saving you from replacing the entire bit.

For smaller diameters, the 200 mm auger bit or the 150 mm version offer an alternative for fence posts or smaller planting jobs. If your site also involves vegetation cutting, a hydraulic hedge trimmer can complement your machine's setup.
