Pocket Hole Tear Out

I've always struggled with tear out when doing pocket hole screws in plywood in cross grain. I usually just take a knife and score the veneer off so I don't catch myself on them. My pocket holes are typically not visible in my projects. If I put the holes with the grain in the veneer, the results are pretty good. If I put them in solid wood, the holes look good. Anyone have any tricks to eliminate this? For reference, I'm using the Harbor Freight pocket hole jig. I like the all metal construction compared to the Kreg jig.

What brand of bit are you using? Is it sharp? Are the flutes razor sharp? Does it fit the jig tight so it shears off the fibers? Does the face of the jig fit tight and flat against the face of the wood? For comparison I use a Kreg jig and a Kreg bit and I have never experienced what you show in the photo. The sleeves in the Kreg are steel. The reviews for the HF jig talk about how bad the bit is and how bad the tearout is with the jig.

Tip: Tape it before you drill.

Other Possibilities:

  1. Your clamping force isn't tight enough and the bit is chattering.
  2. The fit of the bit in the guide may be sloppy. HF is not known for holding tight (or any) tolerances. Is part of what separates HF/Central Machinery from "real" tools.
  3. Your bit is dull. The adhesives in plywood are tough on bits, esp drilling at an angle.
  4. Some combination of all of the above

... don't … shop … at … harbor … freight …

When I buy a type of tool I've never had before (not a known one-shot) I usually buy a basic, cheap (NOT the cheapest) tool. If it lasts, it's all I needed, no $$$ wasted. If it breaks or doesn't last, I replace with the next tier up. Sooner or later they stop breaking or I learn how to use it properly.

+1 Madmark2 and the others. I have the Kreg K4 system. It may be made of plastic, but all the drilling hole guides are metal. The Kreg k4 system also has dust collection ports and an adapter to attach a shop-vac. Allows the drill bit to clean out instead of the drill bit packing up saw dust..

I don't use pocket holes very much. When I do, the Kreg K4 has always given me a clean drill hole, with minimal sanding to clean any possible tear-out. The speed of how fast you feed your drill bit, does make a difference. I've also found the some of the pocket hole systems require to you use their brand of drill bit. Not all pocket hole jigs use the same diameter drill bits. Because with their brand, may have a different size diameter head on their screws.

The K4 and K5 are discontinued. The new models are the 520 and 720. Don't let the numbers fool you. The 720 is not necessarily superior to the 520-it's just different.

The 720 is bench top-based and features their AutoMaXX clamping techhology. It allows you to dial in the pressure and that grip will be constant regardless of the thickness of the board.

The 520 uses a pistol-grip clamping design, and can be used on a board without clamping it to a base. Adding the Pro package, you'll get wings for storage and support plus a clamp for the times you want a bench top solution.
