  • HF Air impact screwdriver Central Pneumatic #90059

    On a lark I bought this from HF for $14.39 (17.99 less a 20% off coupon), it's currently still $17.99.

    I have a couple of cordless impact drivers, one 12V from B&D and the other a 19.2V Craftsman C3; keeping batteries is an expensive proposition. The advantages of an impact driver have been discussed before, notably driving high torque screws by impact rotation which is different than constant torque drill drivers for driving screws and fasteners which require you to provide reaction torque holding the tool. The impact tools use a large number of small impacts balanced by the mass of the tool, it drives much more efficiently and comfortably and avoides breaking the fastener.

    Anyway, the air impact driver has a 1/4" hex drive like my cordless impact drivers, and runs off my air compressor so is available for those driveway construction projects without worrying about battery life or even if the batteries are any good. For a whole lot less dinero (That's Texican for money) than the cost of a battery pack and or a cordless driver.

    Comes with a male QD air connector and a double-ended slot/phillips bit. I ran mine on a 6 gallon pancake air compressor and a 50-foot 1/4" PU hose.

    Seems to work quite well as my cordless impact drivers but I only drove a few screws this past weekend. A bit noisy you have the cool-sounding air tool motor sound as well as the impact sound. Probably in net a bit louder than cordless. Finish is as good as or better than average for HF tools which is say its OK.

    Specs say 15 ft-lbs, 8000 RPM (probably impacts per min) and 6CFM. My compressor is less than 6 CFM, but I think it'll be OK since you don't generally use a driver 100% of the time so the tank can store some air.
    It has a knob to select direction (L&R, R being CW and L being CCW) and another knob for setting torque which is something even my cordless drivers don't have.

    I guess in further testing the torque of this is limited. Spec'ed as 15 ft-lbs which is 180 inch-pounds. MY C3 driver is rated 1500 in-pounds.

    The air driver won't put a 2" screw but halfway into an not-pilot-drilled piece of wood. I think my C3 will when working, but right now I have three dead batteries that won't hold a charge long enough for me to test... My B&D impact driver has two battery packs died of old age. Which sort of makes the air tool a winner by default.

      fixed the link now. Seems if you search for it the search results links are temporary. If you navigate to it by following the product categories then the links are OK.

      Thanks for the write-up. Price is cheap...maybe that says something.

      ultimately, not enough power compared to the battery-electric ones.

  • Review of VIX-type Self Centering drill bits
    by LCHIEN
    I have always had trouble mounting small hardware on small wood boxes, with the hasps and hinges always looking slightly off perfectly square - particularly a problem with flat head screws and countersunk hardware which aligns the hardware to the hole location and centers on the hole.

    I'm talking small wood screws. I place and mark the hardware carefully and mark the center of the hole with a sharp awl.
    The problem comes about with small bits like 1/16 and 5/64 and 3/32"...

  • Grizzly Overarm Blade Guard review.
    by twistsol
    Since my new shop is in the basement, dust collection is a bit more important than when I had my own building and could do as I pleased in the shop. With that in mind, I upgraded the dust collection on my table saw. I purchased the Grizzly Overarm Blade Guard to use with the saw.

    First impressions were that this is an extremely solid and well built unit. It's made mostly of steel and connects to a 4" DC hose. There were a number of issues getting it set up and installed, and a...

  • Kreg KMA 3220 5mm Shelf Pin Jig
    by twistsol



    I decided to look for the rock bottom cheapest 32mm drilling system available that would let let me create real 5mm holes spaced 32mm apart, that was easy to use, and didn’t require a bunch of setup time. I’m really surprised at how much I like this little Keg jig especially when you consider the price of $34.99, and it has everything included. There were a couple of jigs cheaper but you needed to buy a self-centering 5mm bit to go along with them so they would...

  • Knife marking pencil Accutrax
    by LCHIEN
    Here's a tool I found useful for marking. Accutrax pencil blade marking knife.



    I have one I've been using on and off for a while. Its a fine pencil lead in the shape of a utility blade that can be installed in any utility knife handle and used with a straight edge, combination square, saddle square etc. to mark easily seen, fine lines on wood..

    Here's mine. I have not broken it, it seems to be quite sturdy. The sharp edge lasts a long time. I'm still on the...

  • Saddle squares
    by LCHIEN
    Hey, I'm sharing one of my favorite tools. A Veritas Saddle Square. Actually I have two in different sizes. This is the large size for marking 2x4 and 4x4 (shown on 4x4 here). One of those tools that makes woodworking a pleasure.



    They're great for continuing lines from side to side. And even side to opposite side.
    Works really well when the board has a rounded edge or some wane where the edge is not really sharp and square but the two adjacent faces are square to...

  • A Review of the Sommerfeld Router Table and Fence
    by twistsol
    Over the years, Iíve had multiple router tables. Everything from a small aluminum Craftsman benchtop model, to the router mount on my BT3000, to a custom built version in my old ultimate tool stand and another custom built one in the wide table of my saw. In every case there was something missing or just not quite up to par. The Sommerfeld table and fence change all that and meet nearly all my criteria....
