Kreg KMA4700-E Straight Edge Guide XL - 8 Ft - For Circular Saw - For Cross Cut & Rip Cut - Aluminum Guide Rails - Carpentry Tools & Accessories

I bought the XL version of the Kreg straight edge so I can make cuts up to a full sheet of plywood length. Like all of my Kreg tools, this works really well. Accurate cuts become very easy using a hand held circular saw when a table or other saw is less practical. With 4 straight edge pieces that can be used in shorter form, or all 4 quickly and securely joined for long cuts, a handle and spring managed, marking, attaching/clamping and cutting becomes very easy. Finding a long enough straight edge used to be painful. Now I can quickly connect as many of the 4 pieces as needed, mark each end of the material to cut, put the guide in place and cut. One thing to consider - the straight edge saw guide includes two adjustable guides to allow marking where the cut will be, line the straight edge up then push guides out the way and cut. Easy enough, but for storing as compact as possible, I need to remove the guides and set up each time. I choose not to use the two additional plastic guides. Instead I carefully measured my held held saw - exactly 4 inches from the edge to the blade where I want to cut. Now all I do is measure 4 inches from where I actually want to cut, one mark each end of the material, clamp and cut.

Great quality and solid material. Definitely buy again.

This cutting guide can do plywood up to 8 feet long. The guide stays put if you pull hard against the spring to set it. It comes in 4 pieces, and it's easy to assemble with a straight-edge. I was very disappointed to find that when set up as a 4-foot guide it only opens to 47 inches! Cannot cross-cut a 48" plywood without adding another segment.

It makes your cuts straight and true. Takes a few minutes to put it together as it comes in 4 sections. The set screws and the provided Allen wrench are a bit of a miss mach so be careful not to strip them out. It is super light but kind of a pain to disassemble to make smaller so I would recommend just storing it as the full set. The saw blade markers are awesome make it fast to set the correct line, but you have to set them left handed or right handed. They could have made it ambidextrous which would have made this thing basically flawless. It's a fraction of the cost of their tracksaw kit and if you're somewhat handy this will get you 90% there.

I purchased this straight edge guide to replace my normal method of clamping a straight edge to plywood sheets as a saw guide. I am ripping 100+ sheets of MDF and wanted to speed up the process. Background: Hobby builder and home renovator for 12+ years. Medium sized shop space. Pros: Once you learn the clamping mechanism, it is a quick and simple process. Easy assembly (be sure to grab an aluminum level or a square to verify joints are straight. Cons: Flex in the aluminum can cause your straight edge to "bend" and your cut unsquared. Comes in 2' segments to be joined together. Saves spaces in shipping but causes a weaker bond. Bottom Line: This product is probably great in the 4' version, but the XL leaves something to be desired. If it was slightly thicker/more beefy, it would likely hold up better against the slight pressure of the saw ripping down the line. I had high hopes this would speed up my process. KREG takes feedback seriously and will improve the product, but I'll be stuck holding this segmented 8' piece of aluminum until I'm tired of looking at it.

I set up the bars that if I placed the part before or after the line (see pictures) would determine which way i'm cutting. In that, which way I measured. Facing it, if i measure from the left I wanted to have them on the left side of the line so it would be accurate, and if I measured from right, right side of line. This was due to depending on the cuts I had to make, sometimes the greatest amount of plywood left would be on 1 side or the other, but my saw always runs from the handle. It's how I set it up. The thickness of the pointer on the plastic arms is right around the thickness of my blade. It might be off 1/16 from the exact size of the blade, but not enough to make a difference when cutting plywood for cabinets IMO. I am finishing my basement that includes cabinets for a kitchenette. See picture of installed bases pre doors/countertop. These were all cut with this tool on 3/4 plywood. I used an online website to get cuts so i could purchase the least amount of plywood. Used this tool to make all the cuts. The reason for the lines is to double check my measurments. I have a tendacy to measure 3.5" at the 2.5 (opposite side of the 3) without realizing. So I'll use my T square 48" long and make the cut line and just verify that i'm not F'ing up. I also wanted to make sure the cuts were right on the line. Besides some wobble here or there when I wasn't holding it steady against the track, you could just see a sliver of line left. Perfect for how I measure/mark. I think the cabinets look good and this tool was perfect for me and not too expensive.

Works great

I was going to return it, but I was in the middle of a project’, making cabinets for my garage workshop’, so I kept it. Adding or removing sections involves removing 4 very small alllen screws, which hold 4 sliding extension bars for each section. It’s a little time consuming. In full 100 inch cuts, I found it necessary to back up the middle with support blocks screwed or clamped to the woodwork. In order to lock the clamp’, you have to pull the spring loaded handle back’, while sliding the stopper the opposite direction; forward’, to tighten the tool, which is very awkward, often causing the guide to move off your bench marks! After discovering these drawbacks’, I made the necessary adaptations to correct them. I’ve gotten used to it, and I am still using it.

梱包に使われている段ボールと付いてくる物は全てとっておく事をお勧めします。4分割されていて組み上げて使う形です。組み上げに使うのは2.5mmの六角レンチでTハンドルみたいなのがあれば楽に組み立てられます。組み上げは5分もかからないです。使う際にブレが気になる方はクイッククランプ等で締め付ければブレたり動く事はありません。大きな板を切断する方にはおススメです。

Excelente herramienta

Great straight edge, I needed the extra long edge for my project. Important to clamp down with additional clamps.

The clamping system is brilliant, well thought out,should have brought sooner

Excelente herramienta para cortar de manera derecha y sin falla
