I bought the Clam Drill Plate when it first came out and used it an entire season. My review… The trigger assembly is just tricky to get set right since it has to depress the drill trigger. I could never get it set quite right…up/down and every other way to make it flawless. It would never keep the drill constantly running when drilling holes. The drill would always stop, giggle the assembly for the drill to begin running again. I ran both the DeWalt 700 and 900 series drill with this assembly. Great idea but lacks a good trigger assembly.
I bought the plate primarily over concerns with binding in the ice. I’ve heard many stories about guys with just electric drills getting bound and the drill twisting your wrist… Ouch! Since I could never get the Clam Drill Plate trigger assembly to work perfectly, I gave up and went directly to the drill. I’m running a 20v Dewalt DCD985 Brushless Hammerdrill with a 6″ Laser Auger. Once you add the side handle, you end up holding it more like a gas auger. I’ve never had it bind to the point where it’ll twist my wrist.
I keep several 3.0Ah and 1.5Ah batteries on hand. I can drill around 40 holes in 12″ of ice on nice days. The only issue with the lithium batteries is that severe cold affects them. If they get to cold, they don’t last as long and I get reduced down to 20-25 holes. To combat that in really cold weather, I take a hand warmer or two and rubber band them to the side/bottom of the battery. It’s easy to pop the battery off and throw it in your parka pockets.
I would not spend the money on the Clam Drill plate. Put the extra money towards a good Milwaukee or DeWalt drill. You will not go wrong with either brand. But definitely consider a Brushless Hammerdrill with the Side Handle and stay away from the compact (700) series.
As a side note… I had concerns with using the Strikemaster Electric Ice Drill Adapter for fear that if the chuck opens slightly while drilling… down the hole goes the auger. By calling the Clam parts department, you can buy just the “Motor Shaft Adapter” for $5. Pop the chuck off, thread on the adapter, and you than just attach the auger like you do on any gas auger. A threaded design like this is something that Strikemaster should consider for their adapter.
Now if only the water would turn hard soon!
