As stated by others the springs are too stiff, especially for a large number of holes (80) which will wear your arms out. I bought this to drill multiple shallow holes in the vertical sides of an entertainment center to use shelf pins for maximum shelf adjustability. For drilling the same holes repeatedly and wanting them the same this is just not the best tool. The instability of the base combined with the lean "flex" of the guide rods caused as you apply the extra pressure you have to because of the springs make the difference between drilling by hand and using this device basically undetectable. I would have to say, if you're not that concerned, just drill by hand and if you want anywhere near precise, get a drill press of a better intermediate attachment.
I recently purchased the Wolfcraft 4525 Drill Guide for a woodworking project. I think using brad point bits would make centering much more accurate. 2)The blue knobs on top that hold the desired angle seem to come loose often3)Setting the right depth can be tricky because of the pressure of the springs. So here is the good, bad, and ugly.The Good:1) It is a relatively well made tool. It is a cheap, simple, and effective replacement for a drill press. I have dropped it several times while it was still attached to my old B & D 1/2" drill with no damage. I do not have room for a drill press and needed to make some holes for some bookcase shelves. I also think a few modifications to the design could fix the problem.
The spring action and adjustable angle are relatively smooth.2) It helps make repetitive drilling much faster. It is much better than taping the drill bit to mark a desired depth3) It makes pretty good 90 degree holes4) There is nothing else quite like it on the market.5)Stores easilyThe Bad: 1)The play in the slide and bit attachment keeps the bit from always landing in the same spot. But once it is set it does not become unadjusted easily.The ugly:I think Wolfcraft should spend a little more time developing this tool. I would be willing to pay more money for a more well designed unit.
Haven't used it yet, but Sears sells this under the Craftsman brand with the only difference being all plastic bits are black.Would also like to see if I can replace the chuck with a keyless 1/2" one.
I am pleased with the product and the fast and courteous service afforded me by Amazon. I have tried another drill guide, and it is not made as sturdy and strong as the wolfcraft. This guide holds drill very well and enables better accuarcy. thank you very much. cfk
Angle guide is good for drilling wood, but the unstable base is a problem drilling angles in metal and plastic.There needs to be some clamp spots added to the base for drilling into harder surfaces to prevent the bit from 'walking'. Or a better method for starting holes on angles.It is portable, where a drill press is not.Still, the best solution to the problem, so far.
