We've created the smallest guide bearings in the industry!
If you've often wanted to trim and shape small details in tight corners, but were disappointed by the scoring and burning left behind by solid pilot bits, we've got what you've been looking for: eight of the most commonly used profiles in miniature sizes – complete with tiny miniature ball bearing guides. These bits are perfect for small fine work such as signs, lettering, small boxes, guitarmaking/luthier and toymaking; essentially any project that requires tiny flush trimming or shaping. Don't let the small size fool you; these bits are precisely machined and carbide-tipped.

  • 3/16" Bearings stays cool unlike brass pilots
  • Rout the most intricate contours for delicate projects
  • Perfect for crafters & hobbyists
  • Lettering/Signmaking
  • Fine musical instruments

Recommendation: The miniature router bits with 3/16” and 1/4” diameter ball bearing guides were designed for use in intricate and delicate projects with or without tight spaces. Do not cut material more than half the diameter of the bearing and slow down feed to reduce load. Not guaranteed due to their extremely small size.

Faulty bit and awful customer service from KJP

Had an issue with one of the two I purchased. Contacted Amana who told me to get a RMA from KJP. My initial contact was ignored (no response then a confirmation I was being ignored when someone accidentally replied all instead of sending a bcc) Then I was offered the opportunity to return the bit via post at my expense (don't live in Ottawa no mo') provided it had not been used. In my original email I said I got home and used it. The issue was it marred the work and the only way one could see that is if ya used the bit.

Turns out there was a problem the bit was defective and Amana took care of me without any assistance from KJP.

Was a gross interaction and I don't know why Andrew was such a meanie Richard head from the jump.

Really good bit. The pilot drill broke pretty early on. Seems to be a somewhat common issue. So I happened to be back in Ottawa and decided to pop in to KJP. Ran in to Andrew, who had no idea who I was, and asked about buying a replacement pilot drill. He was rude af and told me they don't stock the drill but I could go online and order it tho...

That was very helpful because I wasn't aware you can buy stuff on the internet.
