frayed holes

[barry harper]

ii have been using my jig for a while but lately I have noticed that the right side of my pocket holes are not cutting clean , but seemed to be frayed. dull bit ? , any sugestions ?

[David Dean]

Ya get ready to get a new one but you my what to check your locking collar and see hal warn out it is you my beable to trun it over and use the other side becouse Kreg dosent sale drill bit and collar to gather. But if you need everything go out and get a Kreg-mimi it has the bit and collar and you can use all the exta mimi's for panls. It take's a good year to ware them out. Hope this help's

Probably a dull bit but I have noticed some fraying in pine and other soft woods. Kreg does offer a resharp service

[barry harper]

thanks it was in pine and poplar and less noticable in oak but still there . odd it is only on one side of pocket hole.

[John Schaben]

I have to think about that some. I would expect it to be on your left as you are drilling the hole... I supposte the right side as you would look at it.

Even with a new drill bit, cheap birch plywood frays badly, because the top veneer is only a few mils thick.  Usually some fine sand paper cleans it up easily.  It is only on one side of the hole -- the side with the drill exiting the wood.

Wow, mine did this right out of the box.

It's been recommended to drill the holes at 2000rpm (min), for smooth boring operations---

(as recommended in the owners manual/instructions).

I bore my pocket holes at 2000 - 2500rpm, and have no problems.

I'LL check my speed but dont see that as a problem as the last time i tried varying speeds to see if that was the issue, Thanks

[Ken Darga]

''Speed and feed'' is of utmost importance, in any machining operations, for satisfactory results, in all materials.

I dont no but I wonder if you put painters tape on and then drill through and see  if the splinting is resolved.Just a suggestion but I have really never had it happen to my pocket holes

[Rick]

Jens, have you ever put pocket holes in birch ply?  Last night I prolly drilled over a hundred pocket holes and they all frayed on the right side where the drill exits the hole.

I'm going to try painters tape on a few scraps, and see how that works.
