Great product and fit for all tasks that I needed it for
I use this every day and never misses a beat. One of my teams most used pieces of equipment.
Would buy again
Good quality for the price. Starts and works well. The only negative is it requires 1:40 fuel mix, while the rest of my equipment is 1:50. I can live with that however, a lesser inconvenience that having to dig the holes by hand..
Outstanding
Our ground has very little topsoil and a mix of different types of clay, and this Hyundai Post Hole Borer 51cc has been fantastic. We have used it for several hours (so far) and have no issues.
Hyundai 51cc
Ive been using the Hyundai 51cc Post Hole Borer regularly for both fence lines and large hedge installations, and its been a reliable machine across a variety of jobs. For fencing work, its got more than enough power to punch clean, consistent holes for standard posts. Whether Im running a straight fence line or doing multiple posts in a day, it keeps up without struggling. It saves a massive amount of time compared to manual digging, especially when youve got a full run to get through. Where its actually impressed me is on big hedge installs. When youre planting multiple shrubs or doing long hedge rows, consistency in hole size and depth mattersand this unit makes that easy. It cuts through normal soil well and keeps the workflow efficient, which is key when youre trying to stay productive on larger jobs. The 51cc engine delivers solid torque, and once its warmed up, it runs smoothly. Starting is straightforward once youve got the routine down. Fuel use is pretty standard for a 2-stroke nothing excessive. Handling-wise, its manageable solo, but on tougher ground (clay, roots, or stones), it can grab and kick, so youve got to stay sharp. For long runs or heavier conditions, having a second person on it definitely helps with control and reduces fatigue. Build quality is good for the price point. Its not a top-end commercial auger, but for regular contracting work like fencing and hedge planting, it holds up well if you maintain it properly keep the air filter clean, check bolts, and dont run blunt augers. Overall: A solid, hardworking machine that suits fencing and large-scale hedge installs really well. If you're running regular outdoor jobs and need something efficient without spending top dollar, its a good investment.
Reliable, light and powerful
This is a great product. I have 2x Hyundai petrol machines (auger and chipper) - the motors are highly efficient and reliable. Maybe 3-4 pulls to start cold, then (warmed up) for each hole its a 1 pull start. I find it works better than the heavier hire models. I rip through holes in a few seconds. Little assembly - great for the farm - should have got one ages ago instead of hiring.
Great little tool.
Easy to start. I'm only 60kg and 61 years old, but I've found it easy to drill 200mm diameter holes up to 500mm deep for posts. I'm very happy with this post hole borer.
Post hole borer
It is excellent I am just using it around a lifestyle block Works perfectly
Great Buy
Very happy with my purchase. Great build quality
I wouldn't buy again.
Overall, this post hole borer appears well made, starts easy and has plenty of torque. HOWEVER, it was quite shocking to me there was no reverse gear, and the centrifugal clutch DOES NOT act as a safe guard against kick backs. I've now drilled a hand full of holes. If you're only drilling in clean topsoil or clay, this unit may be all you need, but if you're concerned about hitting a rock, or tree root, as I do regularly, the unit fails hard. I've had it spinning out of control, ripped out of my hands and have been frustrated on several occasions at having to separate the unit from the drill bit, so I can attach a handle to 'unscrew' the bit after getting caught in hard clay, or against a rock - situations you might normally use a reverse gear to unwind the bit from the hole. As a result, I can't recommend this unit, and would suggest looking else where. Note, perhaps I'm missing something and a reverse does exist, but the manual doesn't mention it, and no amount of frustrated searching has allowed me to find a solution.
Post Hole Borer
Goes Well - No problems at all - have already put through paces by drilling circa 100 holes in first week. Good value for the price point.
Post Hole Borer
Easy to start, powerful one man unit, easy to use
Goes well
Started easly after a few pulls. Ran in motor with 2 tanks of petrol. Nice and light unit and not scary to use. I originally thought it needs an emergency stop, not needed, drop to an idle and the auger stops. Could not be easier. My mum used it, shes 85 years old. Mint. Happyness.
Hyundai post hole borer. Good value.
Very pleased with overall quality of this product and attachments. Works well so far, once you get your technique down. Starts efficiently once warm. One pull. Clear instructions. Enough power.
Hyundai post hole borer
Awesome powerful little machine. I'm in the trade so really impressed. Heaps of power and starts almost first pull each time.
Perfect one person post hole borer
I'm a landscaper, so far been using this for planting mostly. it's solid but not heavy. starts well, has some grunt. haven't had it kick back. spits small - to fist sized rocks pretty easily. I'll admit I haven't had a chance to try a heavy clay soil and haven't come across a root yet, so I can't give a full review. I havent dug more than maybe 300mm yet either and haven't used this for a post hole yet. that being said, it's super comfortable to use, there's not heaps of vibration to the wrists and if you forget your muffs it's not crazy loud. overall, I'm glad I purchased this. makes planting a dream.
Hyundai post hole boarer
Easy to start each time. 2 pulls and it's running. Enough power to get the holes dug and not overly heavy.
Hyundai Post Hole Borer
Easy Start, digs well, a lot easier than the old Tas.
Useful tool for lifestyle block owners.
Just an all round easy piece of equipment to use. Starts first pop, light to handle, worth the $$.
Very Satisfied
So far proving to be really great. Starts easily and plenty of power.

Worked perfectly through clay, dirt tree roots and the odd rock
