HF Silver & Demming Drill Bits


  • HF Silver & Deming Drill Bits

    In a recent shop project to make a lathe chuck / center organizer, I needed to drill some holes to accommodate the MT2 shanks of my live centers and drill chucks. For my purposes (a nice snug fit at a certain height), I needed 11/16 holes. None of my forstner bits (also HF) were this size. For some threaded spur center inserts, I needed 9/16 holes. No love there among the forstners either.

    So I found this set of the Silver and Deming bits at HF: http://www.harborfreight.com/silver-...-pc-61802.html

    I bought this with a 20% coupon, which with tax ended up ~$25. The set is nicely packaged in a wooden storage box, and came individually wrapped in plastic and coated in some cosmoline-like protectant. I've only used the 9/16 and 11/16 bits, but they both ran true when chucked up in my DP, and were sharp enough to cut nice, clean holes in my project. I can't attest to longevity, but for the price, it beat having to buy individual bits at the BORG. If this set isn't on our HF gems list yet, I nominate it for consideration.

      Probably too late for you but I recently bought the MLCS forstner set with 6 values - all the odd 1/16ths from 5/16 to 15/16" e.g. 5 7 9 11 13 and 15.

      $18.95 with free USPS shipping and the usual good www.MLCSwoodworking.com service and a nice wood box.

      I bought this filler set from Grizzly a few years back. It's been very handy to have those odd sizes. Funny thing is the quality of the bits are nicer than my 'standard' sized set

      I notice the HF link is no longer a good part number. Silver and Deming generically describes reduced shank bits, originally a product of a firm called Silver and Deming after two machinists who ran it. But now the term pretty much belongs to any reduced shank set of twist drills. You can easily find them at Amazon or eBay by searching for Silver and Deming or just reduced shank bit set

  • A review of the Kreg Precision Trak & Stop Kit
    by twistsol

    I built my miter station last summer and used the Kreg Precision Trak & Stop Kit. The kit was just the starting point. 8 feet of track and a single flip stop didn’t meet my needs since I was building a miter station the width of my shop, nearly 24 feet. I added four 48” pieces of top track and three additional swing stops so I could have two left and two right. Finally, I added metric rules to the top. Total cost breakdown is as follows

  • 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...
