Question about Craftsman 3/8 in. Drill Press Bit, Mortising Chisel

Need the best bit for drilling through books without tearing internal pages

We are marking all of the books that are being moved into our honor system library by drilling a 3/8" hole in the upper left corner on a drill press. What is the best bit to use?

    Here's the solution I found, and it's working well.

    I used a DeWalt 5/16" "Brad Point" Drill bit (DW1708).

    The sharp point starts the hole without twisting paper and the steep groove pulls paper out rapidly.

    I periodically lubricate the bit with beeswax, wiping it clean before drilling again. Beeswax does not foul the pages like an oil might.

If you use a brad point bit or forstner bit or any bit that cuts around the circumference of the hole, you will create a disc of paper (several pages thick) that will spin at the bottom of the hole and impede your drilling, so those are out. If you use a standard twist drill you get a very rough hole and the pages tend to lift up. The simplest and cheapest is a standard twist drill but with scraps wood above and below the book, clamping the book tight. You might try a plug cutter that has an exit hole for the little discs of paper. Or, use a paper drill bit, these are about $40 and I have never tried one.

    This is an excellent answer. BTW a paper drill bit requires a special drill press that allows the scrap to come up through the center of the chuck.

If this is a new tool I would take it back and get it replaced. The only other way to eliminate this problem is to determine if it is the spindle or the chuck and replace the defective unit. Warranty works better.

Yes it does have a Morse taper and you can remove it by gently hitting it with a rubber or nylon mallet.

SOURCE: Craftsman Drill Press chuck problem

It is unless there is a tang on the end. What you need to do is thoroughly clean the parts with something like brake clean to remove all the oil and then wipe with a clean paper towel. What I do it put the arbor into the drill press or the chuck onto the arbor and then put a 2x4 on the table and press the parts together or if you have enough room fully retract the jaws and use the block of wood to "tap" the parts to seat them. Let me know if you need more assistance

First you have to determine if it is the spindle or the chuck assembly. I would go to ereplacementparts.com and look at a breakdown for this tool so you know what the parts look like and then go from there. I couldn't find the schematic on the Ryobi site.

I have tried to turn the camshaft on a 2004 Suzuki Forenza to the timing mark but it would not line up it would not turn anymore what should I do


Not knowing how far your cam timing is off, your valves may be hitting the top one of a pistons. That may be why cam wont turn anymore.
May be best to back up the cam a bit, remove the spark plugs & with screw driver or wooden dowel probe the cylinders to see which piston is near the top.
Then rotate crank a bit to lower piston down the cylinders DO NOT USE STARTER to rotate engine while timing belt is off or valve damage may occur.

I am trying to drill through old encyclopedias, but the drill bits keep snapping in the pages. What type of drill bit can I put on an hand-held drill that will get through the books without breaking?


rx-dk-diy054036_wood-drill-bits_s4x3_lg.jpgI've used 'regular' high speed drill bits for paper, and wood boring bits. I think the wood bits work better, but whatever bit is used the drill flutes have to be cleared out of material. This is done by drilling a little bit at a time and then lifting the drill out of the hole to clear the hole and the drill of shavings. This is essential to do to minimize heat buildup and binding of the drill bit. The drill bit should not break if you take it nice and easy, and drill in small increments .

How do i use a spade bit?


I'm assuming you mean a spade drill bit?

For best results, try clamping a block of hardwood to the back side of the stock before drilling. When the bit approaches the end of the cut, it will be far less likely to blow through with another piece of wood to drill. However, if the stock placed on the back side is softer than the workpiece, or if it is not securely clamped to the workpiece, tear out can still occur.

To use a spade drill bit, mark the center point of the hole to be drilled on the wood, and install the shank of the bit into the drill. Align the point of the pilot tip of the spade drill bit with the mark on the wood, and adjust the angle of the handheld drill so that the shank of the bit is square to the surface of the wood. (Of course, if you're using a drill press, the bit's angle should already be square to the surface of the wood, unless your drill table is not square to the motor).

Depress the trigger of your drill slightly to engage the motor and turn the bit slowly. Hold the drill as still as possible so that the pilot point stays aligned with the mark on the wood. Because pilot tips can often "walk" away from the intended center point of the hole, some woodworkers will pre-drill the pilot hole using a small-diameter twist drill bit that is less likely to walk, and then proceed with the spade drill bit's pilot tip into the pre-drilled pilot hole.

Once the pilot tip is in place and engaged with the wood, increase the speed and proceed to drill the large diameter hole with the spade drill bit. Continue drilling until you reach the opposite side of the wood and the bit pokes out through the completed hole. Slow the speed of the motor, and pull the drill bit out of the completed hole.

We are concernened about screwing the tub into the floor for stability. We have to go through tile and into wood. There are no instructions included for this. Included were 5/16 lag bolt and feet but we do...


The main reason to screw the feet to the floor is to keep the tub from moving which could cause the pipes to leak (either the supply or the drain) Authentic old clawfoot cast iron tubs were usually bolted to the floor because they were so heavy that it took a significant effort to move them, especially on a wood floor. If your tub is light enough that you could move it without a pretty significant push, then you had best bolt it to the floor in at least two places. Drilling holes through tile can be intimidating, but it's not as hard as you might think using an inexpensive masonry drill bit and a carbide tipped scratch awl. I will leave it to you to figure out how to assemble the claw feet to the tub, but here are a couple of important tips for drilling the holes through tile: Mark the hole locations with a felt-tip marker. Then use the carbide tipped scratch awl to gouge a starter divot in the tile. This divot can be pretty small, but it's essential for being able to drill a hole in tile in the right place. Use a variable-speed drill at fairly low speed to drill the hole - don't use a hammer-drill. Also keep a puddle of water where you are drilling to prevent the tile from heating up in one spot and causing the tile to crack. Once you get the hole through to the wood below, switch to a regular drill bit of a smaller size. Good luck, Al K

start with the smallest drill bit possible . it is best to use three sizes in drill bits to get to the final size you need. drill slowly with less pressure than you would normally use.
