I'm not really looking to buy either. My mora hand auger works just fine. My brother on the other hand has been looking for a way to attach his drill to his hand auger for a couple of years. I've been telling him that the other conversion kits were drill killers and not to waist his money. From the demo videos, it sounded like maybe clam figured out how to not kill your drill.
They didn't solve any problem really the 18 volt drills still don't have a clutch and gear box strong enough to last more then a season or two. Basically when guys come into the shop looking to do this , this is the rule of thumb I give them.
4inch to 5 inch Lazer 18 to 24 Volt
6 Inch Lazer 24 Volt
7 inch and 8 inch Lazer auger 36 Volt
On Mora or other straight blade augers
4 inch 18 Volt
5 inch to 6 inch 24 volt
7 thur 8 36 Volt
I am getting a Lazer™ Synthetic this year in 6 inch to run on my 24 volt Cordless. The reason I like the Lazer™ Synthetic for a cordless is the reduced weight saves the clutch.It also cuts faster due to the small difference in the cutting head compared to the regular Lazer. It is pretty close to a Nils in how it cuts.
The one nice thing the Clam kit does is give you nice hand holds like you would have with a power auger which will make it easier to drill holes straight. Some guys have trouble doing that when they are just using the cordless.
