With a sturdy toggle clamp to secure your stock to the jig, and a large frontal clamping recess for securing the jig to the bench, you'll get perfect alignment every time. Thanks to the removable drill guide and portable base, you have the option of taking the jig to large work pieces and awkward locations or slipping it in your pocket for work on the job site. The material support stop guarantees perfect repeatability time after time, and the dust collection shroud aids in chip expulsion for faster, cleaner drilling. Adjustable for 1/2" to 1-1/2" thick stock in 1/8" incremental settings.

Features:

  • 3 tools in 1 - benchtop jig, portable contractor jig, repair jig with addition of spacer blocks to the bottom of drill guide
  • 3-hole drill guide w/hardened steel core-adjustable for 1/2" to 1-1/2" stock thicknesses in 1/8" increments
  • Material support stop swings out of the way for multiple holes
  • Glass reinforced nylon body
  • Wood chip relief-one relief hole for each drill guide hole keeps chips clear for faster drilling and less burning
  • Large clamping recess
  • Sturdy toggle clamp - easily adjusted

KREG K4MS
I'm new to woodworking and my daughter wants a bookcase made. I bought this hoping it does what it's hyped to do. My first project was a charging station for my drills and batteries. It worked as advertised. I recommend purchasing a least one right angle clamp to keep the wood from "walking" as you drive in the screws.

This rocks
This jig is easy to use and set up even with zero experience. The joints it creates are "Rock" solid. If you have never thought you needed this Think Again. No more dowels and messy glue or biscuits.

Kreg Jig K4MS Master System
Ingenious system. It works, it helps speed up the process of creating squared, stable cabinets. Saw my son, who's a finished carpenter, use it to make our floating stairs and was convinced of its many uses. Valuable tool.

Janice W on Dec 13, 2015
BEST ANSWER: I believe mine came with a dvd but I watch different videos on you tube and this thing is worth its weight in gold
I am going to build a kitchen table using 4x4 for legs and 2x4,6 for top What is the difference in the 4 and 5 jigs. Which should I buy?
Melvin V on Nov 13, 2015
BEST ANSWER: Both would work. The 4 has the clamp in the back and the 5 is in the front. So, it is really a preference/convenience thing. When you buy the kits, they do come with different accessories.
Can you add dust collection port to one without it included?
Melissa W on Dec 22, 2015
BEST ANSWER: This is a small, but very useful "hand tool," and the only "dust" generated is the thin spiral that follows the drill bit twist. One might get a small pile of shavings after a while, but barely enough to brush away once or twice.
I am going to build a kitchen table using 2x4 . Which jig do I need 4 or 5 for holes ?
Melvin V on Jul 8, 2015
BEST ANSWER: Tough to answer not knowing your table design. If you are referring to the number of screws per joint, I would think 4 should be sufficient.. Again, all depends on your design.
