One of the most popular uses for jig devices is spacing and locating drill holes, that’s because it provides you with an accurate measurement device by which you can gauge if whether or not your current materials will be compatible with the design you’re aiming for.

The primary purpose of a jig is to allow woodworkers and other material fabricators the ability to repeat precise action, cuts, and other modifications in addition to allowing them to interchange the format and positioning of their work without compromising quality during the manufacturing phase.

Jigs can also be used to guide or hold tools such as drills and saws during the material fabrication stage to ensure that precise adjustments are made.

History Behind The Company: Kreg

Kreg History

Kreg has a very rich history in the tool industry particularly when it comes to their jigs and other sorts of tool and work accessory options that they provide. Because of their incredible track record over the years, Kreg has become one of the largest and most trusted tool accessory manufacturers in the world.

Kreg was started in 1986 by Craig Sommerfield who at the time of inventing the company was in the process of building a home for himself, during the building process Craig encountered a few issues.

One of the main problems he faced when building his home is that he didn’t have access to a device which would allow him to properly connect his dowelled face frame to the kitchen cabinet carcass he was installing.

Since he didn’t want to nail the face frame to the kitchen cabinets and fill in the loose holes with caulking, he designed the first-ever “Craig’s Jig” which had a single-hole pocket-hole jig that was made out of a combination of aluminum and steel.

This unique invention allowed Craig to install his face frames to the interior of his kitchen cabinets while hiding the joints which connected the two pieces from within the view.

After seeing the genius ingenuity and engineering on display by Craig, many of his close coworkers and friends motivated him to build more of the jigs which he eventually did. He would go on to produce multiple replicas of his unique and newly invented jig tool to people at local woodworking shows in his area.

He would continue this same pattern for several years until he finally founded the Kreg Tool Company that woodworkers and other material fabrication specialists love and know today.

Kreg tool products are available in many different countries and regions across the world including the UK, Canada, the United States, and Australia.

Now that we’ve gone over all of the most important historical facts about Kreg, it’s time to take a look at the main differences between the K4 and K5 jig so that you can make sure you’re choosing the correct model for your specific needs.
